SET-UP
1. Crane load ratings are based on the crane being leveled and standing on a firm and
uniform supporting surface.
2. Crane load ratings on outriggers are based on all outriggers 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.
OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. NO 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. EXTRA-CAUTION ZONE – Tipping can occur with some boom/jib combinations at radii
within this area without any load on the hook.
4. The boom angles shown on the Lift Chart give an approximation of the operation 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. 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. Rated lift ratings are based on correct reeving. Deductions must be made for
excessive reeving. Any reeving over the minimum is considered excessive. Deduct for
each foot of excessive wire rope before attempting to lift a load. See HOIST TACKLE
CHART for rope information.
6. When lifting over the jib, the weight of any hook block, slings, and any auxiliary lifting
devices at the boom head must be added to the load.
7. For all boom lengths less than the maximum with the jib erected, the rated loads are
determined by boom angle only in the appropriate column.
8. For all boom lengths less than the listed boom length, the rated load is to be determined by
boom angle.
