1.5 GENERAL

1.5.1 Rated loads as shown on Lifting Charts pertain to this machine as originally manufactured and equipped. Modifications to the machine or use of optional equipment other than that specified can resul t in a reduction of capacity.

1.5.2 Construction equipment can be hazardous if improperly opera ted or maintained. Operation and maintenance of this machine shall be in compliance with the information in the Operator’s Manual supplied with this machine. If thes e manuals are missing, order replacements from the manufacturer through your distributor.

1.5.3 These warnings do not constitute all of the operating conditions for the crane. The operator and job site supervision must read the Operator’s Manual.

1.5.4 This crane and its load ratings are in accordance with ASME/ANSI B30.5.

1.6 DEFINITIONS

1.6.1. LOAD RADIUS – The horizontal distance from the axis of rotation before loading to the center of the vertical hoist line or tackle with a load applied.

1.6.2. LOAD BOOM A NGLE – It is the angle between the boom base sec tion and the horizontal, after lifting the rated load at the rated radius. The boom angle before loading should be greater to account for deflections. The loaded boom angle combined with the boom length give only an approximation of the operating radius .

1.6.3. WORKING AREA – Areas measured in a circular arc about the centerline of rotation as shown in the diagram.

1.6.4. FREELY SUSPENDED LOAD – Load hanging free with no direct external force applied except by the hoist rope.

1.6.5. Side load – Horizontal force applied to the lifted load either on t he ground or in t he air.

1.6.6. EXTRA-CAUTION ZONE – Tipping can occur with some boom/ jib combi nati ons at radii within this area without any load on the hook.

1.6.7. BOOM SIDE OF CRANE – The side of the crane over which the boom is positioned when in an OVER SIDE working posit i on.

1.7 SET-UP

1.7.1. Crane load r atings are based on the crane being leveled and standing on a firm and uniform supporting surface.

1.7.2. Crane load r atings on outriggers are based on all outrigger beams being fully extended / retracted, or in the case of partial extension ratings mechanically pinned in the appropriate position, and the tires raised free of the supporting surface.

1.7.3. Crane load r atings on tires depend on appropriate inflation pressure and the tire conditions. Caution must be exercised when increasing air pressures in tires. Consult Operator’s Manual for precautions.

1.7.4. Consult appr opriat e sec t ion of the Operator’s Manual for more exact desc ripti on of hoist line reeving.

1.7.5. The use of more parts of line than required by the load may result in having insufficient rope to allow the hook block to reach the ground.

1.7.6. Properly maintained wire rope is essential for safe crane operation. Consult Operator’s Manual for proper maintenance and inspection requirements.

1.7.7. When spin-resistant wire rope is used, the allowable rope loading shall be the breaking strength divided by five (5), unless otherwise specified by the wire rope manufacturer.

1.8 OPERATION

1.8.1. CRANE LOAD RATINGS MU ST N OT BE EX CEEDED. DO NOT ATTEMPT TO TIP THE CRANE TO DETERMINE ALLOWABLE LOADS .

1.8.2. When either radius or boom length, or both, are between lis ted values , the smalle r of the two listed load ratings shall be used.

1.8.3. Do not operat e at longer radii than those list ed on the applicable Lift Chart (cross hatched areas shown on range diagrams) as tipping c an occur wit hout a load on the hook.

1.8.4. The boom angles shown on the Lift Charts give an approximation of the operating radius for a specified boom length. The boom angle, before loading, should be

01 - 4 RT55 Rough Terrain Crane

greater to account for boom deflection. It may be necessary to ret ract the boom if maximum boom angle is insufficient to maintain rated radius.

1.8.5. All telescopic sections must be extended synchronically.

1.8.6. Rated loads include the weight of hook block, slings, and auxiliary lifting devices. Their weights shall be subtracted from the listed rated load to obtain the net load that can be lifted.

1.8.7. When lifting over the jib, the weight of any hood block, slings, and auxiliary lifting devices at the boom head must be added to the load.

1.8.8. Rated lifting capacities are based on correct reeving. Deductions must be made for excessive reeving. Any reeving over the minimum required, (see Hoist Tackle Chart), is considered excessive and mus t be accounted for. Deduct for each meter of excessive wire rope before attempting to l ift a load.

1.8.9. When jibs are erec ted but unused, add three (3) times the weight of jib, any hook block, slings, and auxiliary lifting devices at the jib head to the load (jib weight: 952 kg (2099 lbs)).

1.8.10. Rated loads do not excee d 85% on outriggers or 75% on tires, of the tipping load as determined by ASME/ANSI B30.5.

1.8.11. Rated loads are based o n freely suspended loads. No attempt shall be made to drag a load horizontally on the ground in any direction.

1.8.12. The user shall oper ate at reduced rat ings to al low for adv erse j ob conditi ons, such as: soft or uneven ground, out of level conditions, high winds, side loads, pendulum action, jerking or sudden stopping off loads, hazardous conditions, experience of personnel, two-machine lifts, traveling with loads , electric wires, etc, (side pull on boom or jib is hazardous). If wind speed is higher than t he maximum permissible value (45 ft/s (13.8 m/s), grade 6) or it is fulminous during crane operation, stop working and completely retract the boom and place it on the boom support for traveling.

1.8.13. Load ratings are dependent upon the crane being maintained according to manufacturer’s specif ic ations.

1.8.14. It is recommende d that load handling devices, including hooks , and hook blocks, be kept away from boom head at all times.
