Safety Summary
WARNING
• Do not use this hoist or attached equipment for lifting, supporting, or transporting people or lifting or supporting loads over people.
• Powered hoists are designed to provide a 5 to 1 safety factor. The supporting structures and load-attaching devices used in conjunction with this hoist must provide adequate support to handle all hoist operations plus the weight of the hoist and attached equipment. This is the customer’s responsibility. If in doubt, consult a registered structural engineer.
NOTICE
• Lifting equipment is subject to different regulations in each country. These regulations may not be specified in this manual.
The National Safety Council, Accident Prevention Manual for Industrial Operations, Eighth Edition and other recognized safety sources make a common point: Employees who work near cranes or assist in hooking on or arranging a load should be instructed to keep out from under the load. From a safety standpoint, one factor is paramount: conduct all lifting operations in such a manner that if there were an equipment failure, no personnel would be injured. This means keep out from under a raised load and keep out of the intended path of any load.
Ingersoll-Rand Material Handling hoists are manufactured in accordance with the latest ASME B30.16 standards.
The Occupational Safety and Health Act of 1970 generally places the burden of compliance with the user, not the manufacturer. Many OSHA requirements are not concerned or connected with the manufactured product but are, rather, connected with the final installation. It is the owner’s and user’s responsibility to determine the suitability of a product for any particular use. It is recommended that all applicable industry, trade association, federal, state and local regulations be checked. Read all operating instructions and warnings before operation.
Rigging: It is the responsibility of the operator to exercise caution, use common sense and be familiar with proper rigging techniques. See ASME B30.9 for rigging information, American National Standards Institute, 1430 Broadway, New York, NY 10018.
This manual has been produced by Ingersoll-Rand to provide dealers, mechanics, operators and company personnel with the information required to install, operate, maintain and repair the products described herein. It is extremely important that mechanics and operators be familiar with the servicing procedures of these products, or like or similar products, and are physically capable of conducting the procedures. These personnel shall have a general working knowledge that includes:
1. Proper and safe use and application of mechanic’s common
hand tools as well as special Ingersoll-Rand or recommended tools.
2. Safety procedures, precautions and work habits established by accepted industry standards.
Ingersoll-Rand cannot know of, or provide all the procedures by which product operations or repairs may be conducted and the hazards and/or results of each method. If operation or maintenance procedures not specifically recommended by the manufacturer are conducted, it must be ensured that product safety is not endangered by the actions taken. If unsure of an operation or maintenance procedure or step, personnel should place the product in a safe condition and contact supervisors and/or the factory for technical assistance.
3
SAFE OPERATING PROCEDURES
The following warnings and operating instructions have been adapted in part from American National (Safety) Standard ASME B30.16 and are intended to avoid unsafe operating practices which might lead to injury or property damage.
Ingersoll-Rand recognizes that most companies who use hoists have a safety program in force in their plants. In the event you are aware that some conflict exists between a rule set forth in this publication and a similar rule already set by an individual company, the more stringent of the two should take precedence.
Safe Operating Instructions are provided to make an operator aware of dangerous practices to avoid and are not necessarily limited to the following list. Refer to specific sections in the manual for additional safety information.
1. Only allow personnel instructed in safety and operation on this product to operate and maintain the hoist.
2. Only operate a hoist if you are physically fit to do so.
3. When a “DO NOT OPERATE” sign is placed on the hoist controls, do not operate the hoist until the sign has been removed by designated personnel.
4. Read the manufacturer’s operating instructions before operating the hoist.
5. Never lift a load greater than the rated capacity of the hoist (unless for test purposes).
6. Never use the load chain as a sling.
7. Never operate the hoist with twisted, kinked, "capsized" or damaged chain.
8. Be certain the load is properly seated in the saddle of the hook.
9. Do not use load chain as a ground for welding. Do not attach a welding electrode to a hoist or sling chain.
10. Do not use the up and down stops as a means of stopping a hoist. The up and down stops are emergency devices only.
11. Do not leave a load suspended for extended periods.
12. Always stand clear of the load path.
13. Never use the hoist for lifting or lowering people, and never stand on a suspended load.
14. Never carry loads over people.
15. Before each shift, check the hoist for wear or damage. Check brakes, limit stops, etc.
16. Periodically, inspect the hoist thoroughly and replace worn or damaged parts.
17. Follow the lubrication instructions.
18. Do not attempt to repair load chain or hooks. Replace them when they become worn or damaged.
19. Never operate a hoist when the load chain is not centered under the hook. Do not “side pull” or “yard”.
20. Always rig the hoist properly and carefully.
21. Ease the slack out of the load chain when starting a lift. Do not jerk the hoist load.
22. Keep the load chain clean and well lubricated. Do not drag the load chain or hook on the floor.
23. Be certain there are no objects in the way of a moving load.
24. Be certain the air supply is shut off before performing maintenance on the hoist.
25. Do not swing a suspended load.
26. Keep the load block overhead when not in use.
27. After use, or when in a non-operational mode, the winch should be secured against unauthorized and unwarranted use.
28. Avoid collision or bumping of hoists.
29. Pay attention to the load at all times when operating a hoist.
30. Never splice a hoist chain by inserting a bolt between links or by any other means.
31. Do not force a chain or hook into place by hammering, and never insert the point of the hook into a chain link.

NOTICE
WARNING
INSTALLATION
Prior to installing the hoist, carefully inspect it for possible shipping damage. Hoists are supplied fully lubricated from the factory. Lubrication of the load chain is recommended before initial hoist operation.
CAUTION
• Owners and users are advised to examine specific, local or other regulations, including American National Standards Institute and/or OSHA Regulations which may apply to a particular type of use of this product before installing or putting hoist to use.
WARNING
• A falling load can cause injury or death. Before installing, read “SAFETY INFORMATION”.
• The supporting structures and load-attaching devices used in conjunction with this hoist must provide adequate support to handle all hoist operations plus the weight of the hoist and attached equipment. This is the customer’s responsibility. If in doubt, consult a registered structural engineer.
Hoist Checks
Make certain your hoist is properly installed. A little extra time and effort in so doing can contribute toward preventing accidents and helping you get the best service possible. Always make certain the supporting member from which the hoist is suspended is strong enough to support the weight of the hoist plus the weight of a maximum rated load plus a liberal safety factor.
Trolley Mounted Hoist Installation
Refer to Dwg. MHP0866 When installing a trolley on a beam, measure the beam flange and temporarily install the trolley on the hoist to determine the exact distribution and arrangement of the spacers. The total distance between the wheel flanges should be 3/16 to 1/4 inch (5 to 6 mm) greater than the width of the beam flange. The number of spacers between the trolley side plate and the mounting lug on the hoist must be the same in all four locations in order to keep the hoist centered under the I-beam. The remaining spacers must be equally distributed on the outside of the trolley side plates.
• For specific information relating to trolley installation refer to the manufacturers’ manual supplied with the trolley.
HLK Hoist Plain Rigid Trolley
CAUTION
• Before placing this hoist in service, remove square headed pipe plug from oil fill hole and replace with hex headed breather plug attached to caution tag CA210-121.
1. Remove the solid shipping plug located on top of the hoist and install the attached breather plug prior to using the hoist.
2. With the hoist placed in its normal level position check that the gear case oil level is at the check plug on the side of the gear box.
Hoist Mounting
Hook Mounted Hoist Installation
Place hook over mounting structure. Ensure hook is large enough to properly fit on structure. Make sure hook latch is engaged. Ensure the supporting member rests completely within the saddle of the hook and is centered directly above the hook shank. Hoist must freely hang from hook without restriction.
CAUTION
• The supporting member must position on the saddle of the
hook. Ensure hoist does not tilt to one side or the other.
• A minimum of one adjusting spacer must be placed on the outside of the trolley side plates. Ensure correct installation as described in the parts, operation and maintenance manual provided with the trolley.
Trolley bolt nuts (207) and (220) torque requirements: On HL1000K, HL1500K, HL2000K and HL3000K hoists torque to 150 ft lbs (203 Nm). On HL4500K and HL6000K hoists torque to 250 ft lbs (339 Nm).
7
NOTICE
CAUTION
CAUTION
When installing the hoist and trolley on the beam, make certain the side plates are parallel and vertical. After installation, operate the trolley over the entire length of the beam with rated load suspended 4 to 6 inches (100 to 150 mm) off the floor.
CAUTION
• To avoid an unbalanced load which may damage the trolley, the hoist must be centered under the trolley.
NOTICE
• Trolley wheels ride on the top of the lower flange of the beam.
Ensure beam stops are installed prior to operating hoist and trolley.
Chain Container
Refer to Dwgs. TPC451-3 and MHP1029 and the “MAINTENANCE” section for detailed assembly and disassembly information.
NOTICE
• Make certain to adjust the container support such that the chain container does not contact the load chain or hook.
• Operate the hoist to naturally pile chain into the chain container. Piling the chain carelessly into the container by hand may lead to kinking or twisting that may cause chain to jam the hoist.
1. Check the chain container size to make sure the length of load chain is within the capacity of the chain container. Replace with a larger chain container, if required.
2. Attach the chain container to the hoist.
3. Run bottom block to lowest point and run hoist in up direction to feed the chain back into the container.
WARNING
• Always use an air line filter and lubricator with an HLK hoist.
Air Line Lubricator
Refer to Dwg. MHP0191. Always use an air line lubricator with these hoists. Use a lubricator having an inlet and outlet at least as large as the inlet on the hoist motor. Install the air line lubricator as close to the air inlet on the hoist motor as possible. Refer to “ACCESSORIES” in the parts section for the recommended Filter-Lubricator-Regulator.
• Lubricator must be located no more than 10 ft (3 metres) from the hoist motor.
• Shut off air supply before filling air line lubricator.
The air line lubricator should be replenished daily and set to provide lubrication at a minimum rate of 1 to 3 drops per minute adjusted at maximum hoist speed, of SAE 10W oil or a good grade of hydraulic oil.
• Disconnect the hoist from the air supply before installing a
chain container kit.
Air System
The supply air must be clean, lubricated and free from water or moisture. A minimum air supply of 70 scfm (1.96 cu. m/m) at 90 psig (6.3 bar/630 kPa) at the hoist motor inlet is required, during operation to provide rated hoist performance.
Air Lines
The inside diameter of the hoist air supply lines must not be smaller than 1/2 in (13 mm) for up to 12 ft (4 m) lengths and 3/4 in (19 mm) for up to 50 ft (15 m) lengths between the air supply and the hoist. Contact the factory for recommended air line sizes for distances greater than 50 ft (15 m). Before making final connections, all air supply lines should be purged with clean, moisture free air before connecting to unit inlet. Supply lines should be as short and straight as installation conditions will permit. Long transmission lines and excessive use of fittings, elbows, tees, globe valves, etc. cause a reduction in pressure due to restrictions and surface friction in the lines. Fittings used at the inlet of the hoist must have at least a 3/8 in (10 mm) air passage. Use of smaller fittings will reduce performance.
• Do not use automotive type detergent oil. Detergents will delaminate the motor vanes and cause premature failure.
Air Line Filter
Refer to Dwg. MHP0191 It is recommended that an air line strainer/filter be installed as close as practical to the motor air inlet port to prevent dirt from entering the motor. The strainer/filter should provide 10 micron filtration and include a moisture trap. Clean the strainer/filter monthly to maintain its operating efficiency. Refer to "ACCESSORIES" in the parts section for the recommended Filter-Lubricator-Regulator.
Moisture in Air Lines
Moisture that reaches the air motor through the supply lines is the chief factor in determining the length of time between service overhauls. Moisture traps can help to eliminate moisture. Other methods, such as an air receiver which collects moisture before it reaches the motor or, an aftercooler at the compressor that cools the air prior to distribution through the supply lines, are also helpful.
The swivel inlet assembly (includes items 23 through 24C) must be installed on the hoist. Failure to do so may result in a hoist malfunction.
8
Pendant Control Adjustments
The bleed adjustment screws (19) or (336 [old style]) used on hoists with a pendant control are factory adjusted to provide optimum control at 90 psig (6.3 bar/630 kPa) air pressure. If the hoist is used with other air supply pressures, the bleed adjustment screws may require readjustment.
For maximum performance and control, adjust the bleed screws (19) or (336 [old style]) as follows:
1. Loosen the adjustment screw locknut (21) or (337 [old style]).
2. Turn the adjustment screw (19) or (336 [old style]) counterclockwise approximately one third (1/3) of a turn.
3. Fully depress the pendant throttle lever (165) and hold in depressed position. Turn the adjustment screw clockwise until the piston rod fully retracts. This adjustment will provide a good balance of spotting control and maximum hoist speed. If better spotting control is desired, slowly back out the adjustment screw a little at a time until the spotting control is suitable.
4. When adjustment is complete, hold the adjustment screw in position and tighten the adjustment screw locknut (21) or (337 [old style]).
5. Repeat steps 1 through 4 for opposite pendant throttle lever.
Storing the Hoist
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water.
3. Oil the load chain, hook pins and hook latch.
4. Place in a dry location.
5. Plug hoist air inlet port.
6. Before returning hoist to service follow instructions for ‘Hoists not in Regular Service’ in the “INSPECTION” section.
9
OPERATION
WARNING
The four most important aspects of hoist operation are:
1. Follow all safety instructions when operating hoist.
2. Allow only people instructed in safety and operation on this product to operate hoist.
3. Subject each hoist to a regular inspection and maintenance procedure.
4. Be aware of the hoist capacity and weight of load at all times.
WARNING
• Do not use this hoist for lifting, supporting or transporting
people or lifting or supporting loads over people.
Operators must be physically competent. Operators should have no health condition which might affect their ability to react, and they must have good hearing, vision and depth perception. The hoist operator must be carefully instructed in his duties and must understand the operation of the hoist, including a study of the manufacturer’s literature. The operator must be aware of proper methods of hitching loads and should have a good attitude regarding safety. It is the operator's responsibility to refuse to operate the hoist under unsafe conditions.
Initial Operating Checks
Hoists are tested for proper operation prior to leaving the factory. Before the hoist is placed into service the following initial operating checks should be performed.
1. After installation of trolley mounted hoists, check to ensure the hoist is centered below the trolley.
2. Check for air leaks in the supply hose and fittings to pendant, and from pendant to manifold.
3. When first running the hoist or trolley motors a small amount of light oil should be injected into the inlet connection to allow good lubrication.
4. When first operating the hoist and trolley it is recommended that the motors be driven slowly in both directions for a few minutes.
5. Operate the trolley along the entire length of the beam.
6. Inspect hoist and trolley performance when raising, moving and lowering test load(s). Hoist and trolley must operate smoothly and at rated specifications prior to being placed in service.
7. Check that trolley (if equipped) and hook movement is the same direction as arrows or information on the pendant control.
8. Raise and lower a light load to check operation of the hoist brake.
9. Check hoist operation by raising and lowering a load equal to the rated capacity of the hoist 4 to 6 inches (100 to 150 mm) off the floor.
10. Check operation of limit devices.
11. Check to see that the hoist is directly over the load. Do not lift the load at an angle (side pull or “yard”).
12. Check to see that the hoist is securely connected to the overhead crane, monorail, trolley or supporting member.
13. Check to see that the load is securely inserted in the hook, and that the hook latch is engaged.
• The hook latch is intended to retain loose slings or devices
under slack conditions. Hook latches are not intended to be an antifouling device, so caution must be used to prevent the latch from supporting any of the load.
Hoist Controls
Pendant Controls
The HLK hoist can be supplied with an optional manual pull chain control or a one, two or three function pendant depending on application. For detailed information on these products refer to Ingersoll-Rand Manual Form Number P6778 or contact your nearest distributor or the factory. Operation of the hoist is the same for all pendants listed in this section:
1. To lift a load, depress the hoist pendant raise lever.
2. To lower a load depress the hoist pendant lower lever.
3. To throttle lift or lowering speed, regulate the amount the pendant lever is depressed. Depress lever completely for maximum speed; depress lever partially for slower speeds.
4. To stop lift or lowering function, release the lever. Lever will spring return to off and hoist motor will stop.
Single Function, Two Lever Pendant
Refer to Dwg. MHP0427. The two lever pendant is the standard pendant supplied with the HLK and is designed to provide hoist operation only. Hoist operation must correspond to the directions indicated by the arrows located on the pendant levers.
(Dwg. MHP0427)

INSPECTION
WARNING
• All new, altered or modified equipment should be inspected and tested by personnel instructed in safety, operation and maintenance of this equipment to ensure safe operation at rated specifications before placing equipment in service.
• Never use a hoist that inspection indicates is damaged.
Frequent and periodic inspections should be performed on equipment in regular service. Frequent inspections are visual examinations performed by operators or service personnel and include observations made during routine equipment operation. Periodic inspections are thorough inspections conducted by personnel trained in the safety, operation and maintenance of this equipment. ASME B30.16 states inspection intervals depend upon the nature of the critical components of the equipment and the severity of usage. The inspection intervals recommended in this manual are based on intermittent operation of the hoist eight hours each day, five days per week, in an environment relatively free of dust, moisture and corrosive fumes. If the hoist is operated almost continuously or more than eight hours each day, more frequent inspections will be required. Careful inspection on a regular basis will reveal potentially dangerous conditions while still in the early stages, allowing corrective action to be taken before the condition becomes dangerous. Deficiencies revealed through inspection, or noted during operation, must be reported to designated personnel trained in safety, operation and maintenance of this equipment. A determination as to whether a condition constitutes a safety hazard must be decided, and the correction of noted safety hazards accomplished and documented by written report before placing the equipment in service.
2. HOOKS. Check for wear or damage, increased throat width, bent shank or twisting of hook. Replace hooks which exceed the throat opening and/or saddle dimension discard widths specified in Table 2 (refer to Dwg. MHP0040) or exceed a 10° twist (refer to Dwg. MHP0111). If the hook latch snaps past the tip of the hook, the hook is sprung and must be replaced. Replace Bullard Burnham hooks if the gate no longer contacts the hook tip. Refer to Dwg. MHP0662. Refer to the latest edition of ASME B30.10 “HOOKS” for additional information. Check hook support bearings for lubrication or damage. Ensure they swivel easily and smoothly.
Records and Reports
Inspection records, listing all points requiring periodic inspection should be maintained for all load bearing equipment. Written reports, based on severity of service, should be made on the condition of critical parts as a method of documenting periodic inspections. These reports should be dated, signed by the person who performed the inspection, and kept on file where they are readily available for review.
Load Chain Reports
Records should be maintained documenting the condition of load chain removed from service as part of a long-range load chain inspection program. Accurate records will establish a relationship between visual observations noted during frequent inspections and the actual condition of the load chain as determined by periodic inspection methods.
Frequent Inspection
On hoists in continuous service, frequent inspection should be made by operators at the beginning of each shift. In addition, visual inspections should be conducted during regular operation for any damage or evidence of malfunction (such as abnormal noises).
1. OPERATION. Check for visual signs or abnormal noises (grinding etc.) which could indicate a potential problem. Make sure controls function properly and return to neutral when released. Check load chain feed through the hoist and bottom block. If chain binds, jumps, is excessively noisy or "clicks", clean and lubricate the chain. If problem persists, replace the chain. Do not operate the hoist until all problems have been corrected.
12
3. UPPER AND LOWER LIMIT DEVICE. Test operation
with no load slowly to both extremes of travel. Upward travel must stop when the bottom block or stop ring on chain hits hoist limit arm. Downward travel must stop when the loop at the unloaded end of the chain decreases and activates the limit arm.
4. AIR SYSTEM. Visually inspect all connections, fittings,
hoses and components for indication of air leaks. Repair any leaks found. Check and clean the filter in the inlet stud (24) and the inlet strainer (24C) if equipped.
5. CONTROLS. During operation of hoist, verify response to
pendant, or pull chain, is quick and smooth. Ensure that the controls return to neutral and hoist operation stops when released. If hoist responds slowly or movement is unsatisfactory, do not operate hoist until all problems have been corrected.
6. HOOK LATCH. Make sure the hook latch or gate is
present and operating. Replace if necessary.
CAUTION
• Do not use hoist if hook latch or gate is missing or damaged.
7. LOAD CHAIN. Examine each link for bending, cracks in
weld areas or shoulders, traverse nicks and gouges, weld splatter, corrosion pits, striation (minute parallel lines) and chain wear, including bearing surfaces between chain links (refer to Dwg. MHP0102). Replace a chain that fails any of the inspections. Check chain lubrication and lubricate if necessary. Refer to ‘Load Chain’ in “LUBRICATION” section.
CAUTION
• The full extent of load chain wear cannot be determined by visual inspection. At any indication of load chain wear inspect chain and chain wheel in accordance with instructions in ‘Load Chain’ listed in “Periodic Inspection” section.
8. LOAD CHAIN REEVING. Ensure welds on standing links are away from the powered chain wheel. Reinstall chain if necessary. On hoists with multiple chain falls, make sure load chain is not capsized, twisted or kinked. Adjust as required.
Periodic Inspection
Frequency of periodic inspection depends on the severity of usage:
NORMAL HEAVY SEVERE
yearly semiannually quarterly
Disassembly may be required for HEAVY or SEVERE usage. Keep accumulative written records of periodic inspections to provide a basis for continuing evaluation. Inspect all the items in "Frequent Inspection". Also inspect the following:
1. FASTENERS. Check all rivets, split pins, capscrews and nuts. Replace if missing or tighten if loose.
2. ALL COMPONENTS. Inspect for wear, damage, distortion, deformation and cleanliness. If external evidence indicates the need, disassemble. Check gears, shafts, bearings, sheaves, chain guides, springs and covers. Replace worn or damaged parts. Clean, lubricate and reassemble.

3. HOOKS. Inspect hooks carefully for cracks using magnetic particle or other suitable nondestructive method. Inspect hook retaining parts. Tighten or repair, if necessary.
4. LOAD CHAIN WHEELS. Check for damage or excessive wear. Replace if necessary. Observe the action of the load chain feeding through the hoist. Do not operate a hoist unless the load chain feeds through the hoist and hook block smoothly and without audible clicking or other evidence of binding or malfunctioning.
5. MOTOR. If performance is poor, disassemble the motor and check for wear or damage to bearings and shafts. The parts should be cleaned, lubricated and reassembled. Replace worn or damaged parts.
6. BRAKE. Raise a load equal to the rated capacity of the hoist 4 to 6 inches (100 to 150 mm) off the floor. Verify hoist holds the load without drift. If drift occurs, disassemble. Remove brake discs as described in the “MAINTENANCE” section. Check and clean the brake parts each time the hoist is disassembled. Replace the brake discs if the thickness is less than 0.090 inch (2.29 mm).
7. SUPPORTING STRUCTURE. Check for distortion, wear and continued ability to support load.
8. TROLLEY (if equipped). Check that the trolley wheels track the beam properly and clearance between each wheel flange and beam is correct, 3/32 to 1/8 in. (2 to 3 mm). Check that wheels and beam are not excessively worn. Inspect side plates for spreading due to bending. Do not operate the hoist until any problems have been determined and corrected.
9. LABELS AND TAGS. Check for presence and legibility. Replace if necessary.
10. LOAD CHAIN END ANCHORS. Ensure both ends of load chain are securely attached. Secure if loose, repair if damaged, replace if missing.
11. LOAD CHAIN. Measure the load chain for wear over a five link section as shown in Dwg. MHP1291. Pay particular attention to the most frequently reeved links. When any five links in the working length reaches or exceeds the discard length shown in Table 3, replace the entire chain. Always use a genuine Ingersoll-Rand Material Handling replacement chain.

Zinc plated load chain is standard on HLK hoists built after January 1996. Always use stainless steel load chain on HL1000KR Spark Resistant Hoists.
12. CHAIN CONTAINER. Check for damage or excessive wear and that chain container is securely attached to the hoist. Secure or replace if necessary.
13. LIMIT ASSEMBLY. Check throttle lever moves freely. To limit hook downward travel the loop in the slack chain side must contact the throttle lever. To limit hook upward travel the bottom hook block, or stop ring, must contact the throttle lever. To test “UP” and “DOWN” travel limits first run hoist slowly with no load to verify proper function. Repeat test at full speed with no load to verify proper function. On Hoist Models HL4500K and HL6000K the throttle lever (35) may require minor adjustment to provide adequate clearance with the upper suspension block.

LUBRICATION
WARNING
To ensure continued satisfactory operation of the hoist, all points requiring lubrication must be serviced with the correct lubricant at the proper time interval as indicated for each assembly. Correct lubrication is one of the most important factors in maintaining efficient operation.
The lubrication intervals recommended in this manual are based on intermittent operation of the hoist eight hours each day, five days per week. If the hoist is operated almost continuously, or more than the eight hours each day, more frequent lubrication will be required. The lubricant types and change intervals are based on operation in an environment relatively free of dust, moisture, and corrosive fumes. Use only those lubricants recommended. Other lubricants may affect the performance of the hoist. Approval for the use of other lubricants must be obtained from your Ingersoll-Rand Technical Support Department or distributor. Failure to provide proper lubrication may result in damage to the hoist and/or its associated components.
INTERVAL LUBRICATION CHECKS
Start of each shift (Operator)
Weekly (Maintenance personnel)
Monthly (Maintenance personnel)
Yearly (Maintenance personnel)
Note: Intervals are based on hoist operation in a normal environment as described in the “INSPECTION” section. In HEAVY or SEVERE operating conditions adjust lubrication intervals accordingly.
General Lubrication
Whenever a Series HLK Hoist is disassembled for overhaul or replacement of parts, lubricate as follows:
1. Coat all motor parts with a light film of Ingersoll-Rand
Pneu-Lube® Medium Oil No. 50 or a good quality hydraulic oil before assembling.
Check flow and level of air line lubricator (1 to 3 drops per minute) when operating hoist at maximum motor speed.
Clean and lubricate load chain. Lubricate hook latch and pivot points. Inspect and clean or replace air line filter.
Drain and replace housing oil.
CAUTION
• Do not use automotive type detergent oil. Detergents will delaminate the motor vanes and cause premature failure.
2. Apply a coating of Ingersoll-Rand No. 70 Grease or
multipurpose grease to the throttle shaft bearings (2) before assembly.
3. Fill the gear case to the level plug on the side of the
housing (1) with Ingersoll-Rand No. 62 oil, or Texaco Meropa No. 220. Replace oil level plug and vent plug after filling.
4. The top and bottom hooks are supported by thrust bearings.
These bearings must be packed with Ingersoll-Rand No. 68 grease or a standard No. 2 multipurpose grease at regular intervals. Neglect of proper lubrication will lead to bearing failure.
In Line Lubricator
Lubricate the motor with Ingersoll-Rand Pneu-Lube Oil No. 10 (or SAE 10), or No. 50 (SAE 20 or 20W) non­detergent motor oil from an in-line lubricator. The use of detergent oil may cause premature failure.
Load Chain
• Failure to maintain clean and well lubricated load chain will result in rapid load chain wear that can lead to chain failure which can cause severe injury, death or substantial property damage.
1. Lubricate each link of the load chain weekly. Apply new lubricant over existing layer.
2. In severe applications or corrosive environments, lubricate more frequently than normal.
3. Lubricate hook and hook latch pivot points with same lubricant used on the load chain.
4. If required, clean chain with acid free solvent to remove rust or abrasive dust buildup and lubricate the chain.
5. Use Ingersoll-Rand LUBRI-LINK-GREEN to 90 EP oil.
Hook and Suspension Assemblies
1. Lubricate the hook and hook latch pivot points. Hook and latch should swivel/pivot freely.
2. Use Ingersoll-Rand LUBRI-LINK-GREEN® or a SAE 50 to 90 EP oil.
3. On HL4500K and HL6000K hoists lubricate the idler wheel bearings (107) in the upper suspension housing (101) and lower hook block (123) with Ingersoll-Rand No. 68 Grease or a good quality No. 2 multipurpose grease.
4. On HL4500K and HL6000K hoists after each 300 hours of operation or more frequently if hoist is operating in a contaminated atmosphere, inject 2 or 3 shots of grease from a grease gun into grease fittings (111) in the end of the idler wheel shafts (110).
Housing
Remove the oil level plug from the side of the housing (1). If the oil level is below the tapped hole, remove the vent plug and add a sufficient amount of Ingersoll-Rand No. 62 oil (Texaco Meropa No. 3 or Texaco Meropa No. 220). Reinstall the oil level plug and vent plug.

CAUTION
MAINTENANCE
WARNING
• Never perform maintenance on the hoist while it is supporting a load.
• Before performing maintenance, tag controls:
• Only allow personnel instructed in service and repair of this hoist to perform maintenance.
• After performing any maintenance on the hoist, dynamically test hoist to 100% of its rated capacity, in accordance with ASME B30.16 standards, before returning hoist to service. Testing to more than 100% of rated capacity may be required to comply with standards and regulations set forth in areas outside of the USA.
• Shut off air system and depressurize air lines before performing any maintenance.
Maintenance Intervals
The maintenance interval chart is based on intermittent operation of the hoist eight hours each day, five days per week, in an environment relatively free of dust, moisture and corrosive fumes. If the hoist is operated almost continuously or more than eight hours each day, more frequent maintenance should be performed.
INTERVAL MAINTENANCE CHECK
Start of each shift (Operator or Maintenance Personnel)
Semiannually (Maintenance Personnel)
Yearly (Maintenance Personnel)
DANGER - DO NOT OPERATE -
EQUIPMENT BEING REPAIRED.
Make a thorough visual inspection of the hoist for damage. Do not operate the hoist if damaged.
Operate the hoist in both directions. Hoist must operate smoothly without sticking, binding or abnormal noises. Check the operation of the brake.
Inspect the brake. Clean or replace parts as required. Adjust brake as necessary.
Inspect the hoist gearing, shafts and bearings for wear and damage. Repair or replace as necessary.
Check all the supporting members, including the suspension, fasteners, nuts, sheaves and rigging, etc. for indications of damage or wear. Repair or replace as required.
2. Never disassemble the hoist any further than is necessary to accomplish the needed repair. A good part can be damaged during the course of disassembly.
3. Never use excessive force when removing parts. Tapping gently around the perimeter of a cover or housing with a soft hammer, for example, is sufficient to break the seal.
4. Do not heat a part with a flame to free it for removal, unless the part being heated is already worn or damaged beyond repair and no additional damage will occur to other parts.
In general, the hoist is designed to permit easy disassembly and assembly. The use of heat or excessive force should not be necessary.
5. Keep the work area clean to prevent dirt and other foreign matter from getting into bearings and other moving parts.
6. All seals, gaskets and ‘O’ rings should be discarded once they have been removed. New seals, gaskets and ‘O’ rings should be used when assembling the hoist.
7. When grasping a part in a vise, always use leather or copper covered vise jaws to protect the surface of the part and help prevent distortion. This is particularly true of threaded members, machined surfaces and housings.
8. Do not remove any part which is press fit in or on a subassembly unless the removal of the part is necessary for repairs or replacement.
9. To avoid damaging bearings during hoist assembly or disassembly always tap or press on the bearing inner race for shaft fit bearings or the outer race for bore fit bearings.
10. If repair work can only be conducted above body height, suitable working platforms or ladders should be made available.
Load Chain Care
Keep the chain well lubricated as instructed in the “LUBRICATION” section. Never operate a hoist when the load chain does not flow freely and smoothly into and out of the chain wheel(s), or when it makes noises indicative of binding or other malfunctions. If the chain is visibly damaged replace the chain and examine the chain wheel and chain guard. Install a new chain wheel if the old one is visibly worn. Install a new guard if the old one is broken or distorted. Refer to “INSPECTION” section for information on load chain inspection.
General Maintenance Instructions
All maintenance work performed on the hoist must be recorded with the date in the inspection report.
Proper use, inspections and maintenance increase the life and usefulness of your Ingersoll-Rand equipment. During assembly, lubricate gears, nuts, capscrews and all machined threads with applicable lubricants. Use of antiseize compound and/or thread lubricant on capscrew and nut threaded areas prevents corrosion and allows for ease of disassembly of components.
It is recommended that all maintenance work on the hoist be performed on a bench in a clean, dust free work area. During the process of disassembling the hoist, observe the following:
1. Turn off air system and depressurize air lines before performing any maintenance. Disconnect air line from hoist.
• The full extent of load chain wear cannot be determined by visual inspection. At any indication of load chain wear inspect chain and chain wheel. Refer to “INSPECTION” section.
The standard chain provided with this hoist is case hardened to a depth of 0.010 to 0.012 inch (0.25 to 0.35 mm). When the outer hardened case layer is worn through, additional wear will progress rapidly and the strength of the chain will be considerably reduced. Additionally, the chain will no longer fit the pockets in the hoist chain wheel properly causing the chain wheel to wear rapidly. This will greatly increasing the chance of hoist malfunction and chain breakage. The hoist chain wheel is designed to outlast several chain replacement cycles if the chain is replaced as recommended.
