STABILITY

Know the crane components and their capabilities and limitations. Overloading the crane may result in serious injury to self and others, and damage to the equipment and immediate surroundings.

Never exceed manufacturer’s load ratings. These ratings are based on the machine’s hydraulic, mechanical, and structural design rather than stability.

The supporting surface under the service truck must be able to support the weight of the machine and its load. Use outrigger pads if necessary.

Park the vehicle on level ground and extend the outriggers fully out and then down.

Keep feet and legs clear when lowering outrigger jacks.

Never operate the crane without making sure the outriggers ar ground.

Set the parking brake and disengage the drive axle before attempting a lift.

LOAD SAFETY

Operate the crane in compliance with the load capacity chart at all times. Know the weight of the load being lifted. Do not r the overload device to determine maximum rated loads. If the crane is picking more than the maximum rated load, the overlor protection device may be malfunctioning. Discontinue use immediately and contact Stellar Customer Service for support.

Never use a sling bar or anything larger than the hook throat that could prevent the hook latch fr safety feature.

Chapter 2 - Operation

Operation 5

This chapter contains information regarding the operation of Stellar manufactured telescopic cranes. Please study the following pages to ensure your familiarity with the operation process. This understanding is vital to the safe and efficient operation of the crane.

Job-Site Set-Up

Thoroughly plan the lift before positioning the vehicle. Consider the following:

1. The vehicle should be positioned in an area free from overhead obstructions to eliminate the need for repositioning.

2. Position the vehicle so that it is impossible for any portion of the equipment to come within the minimum required safe distance of any power line. Maintain a clearance of at least 10 feet between any part of the crane, load line, or load, and any electrical line or apparatus carrying up to 50,000 volts. One foot additional clearance is required for every additional 30,000 volts or less. Remember to allow for winds that cause power lines to sway. It is recommended that a signal person be used when the vehicle is set-up near power lines.

3. The vehicle should also be positioned on a firm and level surface that will provide adequate support for the outrigger loading. Use extreme caution when setting up near over excavations.

4. The parking brake must be set on the vehicle and the drive axle disengaged before performing a crane operation.

5. The outriggers must be extended to stabilize the truck before beginning operation.

Inspection Checklist

For a more detailed outline of scheduled inspection points, refer to the Stellar Inspection Checklist at the end of this chapter. This list is an excellent guide for the inspection tasks that will help maintain the quality of your Stellar product. Feel free to photocopy the checklist as needed.

ATTENTION

Every six (6) months,

Stellar Industries recommends the first

filter change to occur after the first 250

hours of service.* The second, and

every subsequent change, should

occur after every 1,000 hours of

service. By following these guidelines,

the hydraulic oil should last up to

6,500 hours.

*Note: These recommendations are based on normal

working parameters. If operating in less than favorable

conditions (excessive dust, moisture, etc.), be sure to check

the filter gauge often for filter change notice.

remove the hydraulic

pump from the PTO and

lubricate the splines using Chelsea Lubricant #379831 or Stellar PN 20885. Failure

to lubricate shaft splines will

cause damage to the PTO

and Hydraulic pump.

Wire Rope Maintenance

Wire Rope Inspection Points

While inspection of the entire rope is required, attention should be directed to these critical points:

1. Pick-up Points for signs of wear due to stress from repeated lifts.

2. End Attachments for corrosion and broken wires at both ends of the rope.

Drums for signs of corrugation and wear that may lead to wire damage. Sheaves to ensure that each sheave has

4. the proper groove size and contour.

5. Abuse Points for heavy amounts of scuffing and scraping.

It is important to perform detailed inspections of all ropes associated with the crane. These inspections can be divided into two types:

1. Frequent Inspection

A. All running ropes should be inspected

once each working day. These visual observations will be concerned with discovering damage that may be an immediate hazard. The following concerns should be addressed:

1. Distortion of the rope.

2. General corrosion.

3. Broken or cut strands.

B. Use caution while inspecting sections of

rapid deterioration.

C. Use caution while inspecting boom

hoist ropes. Proper inspection is critical but difficult.

Periodic Inspection

A. Inspection frequency will be

determined by a qualified person and will be based on such factors as expected rope life, environment conditions, capacity of typical lifts, rates of usage, and exposure to shock loads. Periodic inspection needs to be performed at least annually.

B. Periodic inspections will be performed

by a qualified individual and will cover the entire length of the rope. Only the

surface wires of the rope need to be inspected. This inspection will be concerned with discovering damage that may be an immediate hazard. The following concerns should be addressed:

1. Distortion of the rope.

2. General corrosion.

3. Broken or cut strands.

4. Reduction of rope diameter.

5. Corroded or broken wires at end connections.

6. Corroded, cracked, bent, worn, or improperly applied end connections.

C. Use caution when inspecting the

following:

1. Sections in contact with saddles, equalizer sheaves, or other sheaves where rope travel is limited.

2. Sections of the rope at or near ends with corroded or broken wires.

Wire Rope Replacement

Rope replacement guidelines are as follows:

1. Broken wires, including standing ropes with more than two broken wires in one lay or more than one broken wire at an end connection.

2. Wear of one-third the original diameter of the outside wires.

3. Distortion of the rope structure.

4. Evidence of heat damage.

5. Reductions from nominal diameters of more than 1/64 in. (0.4 mm) for diameters from 5/16 in.(19.0 mm) and 1/32 in. (0.8 mm) for diameters from 3/8 in. (9.5 mm) to and including 1/2 in. (13.0 mm).

Wire Rope Maintenance

Proper maintenance is key in ensuring a long lasting rope. These three tips will help:

1. Store the rope to prevent damage.

2. Avoid objects that may scrape, bend, or crush the wires of the rope.

3. Always keep the rope well-lubricated.

Holding Valve Inspection Procedure

The cylinders are equipped with holding valves that prevent sudden movement of the cylinder rods in the event of a hydraulic hose or hydraulic component failure. The valve is checked in the following manner:

1. Identify the cylinder in question.

2. Identify the holding valves and the cylinder direction in question.

a. Cylinder Extend. b. Cylinder Retract.

3. Place the machine so that the cylinder will be located in the appropriate testing

position.

4. Pick the load (Do not exceed capacity, rated or stability).

5. Disengage hydraulics.

6. Operate crane functions.

A. If the cylinder creeps (lowering the

load), replace the holding valve.

B. If the cylinder does not creep (load

stays suspended), the valve is operational.

Gear-Bearing Bolt Maintenance

Anytime a gear-bearing bolt is removed, it must be replaced with a new bolt of the identical grade and size. Once a bolt has been torqued to 75% of its proof load and then removed, the torque coefficient may no longer be the same as when the bolt was new thus giving indeterminate damp loads after torquing.

Warning!

Failure to replace gear-bearing bolts may result in bolt failure due to metal fatigue causing serious injury or even death.

1. Bolt manufacturer’s particular specifications should be consulted when provided.

2. Flat washers of equal strength must be used.

3. All torque measurements are given in foot-pounds. To convert to inch-pounds, multiply by 12.

4. Torque values specified are for bolts with residual oils or no special lubricants applied. If special lubricants of high stress ability, such as Never-Seez compound graphite and oil, molybdenum disulphite, colloidal copper or white lead are applied, multiply the tor

que values in the charts by the factor .90. The use of Loctite does not affect the tor

que values listed

above.

5. Torque values for socket-head capscrews are the same as for Grade 8 capscrews.
