01 - 4 RT55 Rough Terrain Crane
1.7 SET-UP
1.7.1. Crane load ratings are based on the crane being leveled and standing on a firm
and uniform supporting surface.
1.7.2. Crane load ratings 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 ratings 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 appropriate section of the Operator’s Manual for more exact description 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 MUST NOT BE EXCEEDED. DO NOT ATTEMPT TO TIP
THE CRANE TO DETERMINE ALLOWABLE LOADS.
1.8.2. When either radius or boom length, or both, are between listed values, the smaller
of the two listed load ratings shall be used.
1.8.3. Do not operate at longer radii than those listed on the applicable Lift Chart (cross
hatched areas shown on range diagrams) as tipping can occur without
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
