1.7 OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. DO NOT ATTEMPT TO TIP
THE CRANE TO DETERMINE ALLOWABLE LOADS.
2. When either radius or boom length, or both, are between listed values, the smaller of
the two listed load ratings shall be used.
3. Do not operate at longer radii than those listed on the applicable Lift Chart (cross
hatched areas
load on the hook.
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 greater
to account for boom deflection. It may be necessary to retract the boom if maximum
boom angle is insufficient to maintain rated radius.
5. All telescopic sections must be extended synchronically.
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.
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.
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 must be
accounted for. Deduct for each meter of excessive wire rope before attempting to lift a
load.
When jibs are erected 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)).
7. Rated loads do not exceed 85% on outriggers or 75% on tires, of the tipping load as
determined by ASME/ANSI B30.5.
8. Rated loads are based on freely suspended loads. No attempt shall be made to drag a
load horizontally on the ground in any direction.
