Chapter 2 Operation 17
b) Lash or restrain the empty hook so that it cannot swing freely.
c) Do not leave loads suspended from the hook.
8 When rotating the crane, avoid sudden starts and stops. When reversing rotation direction,
pause to allow load swing to subside before rotating in the opposite direction.
9 Do not use this crane for transporting or lifting personnel.
Power Failure
If power fails during operations:
1 Move all controls to the off or neutral position.
2 Land the suspended load, if practical.
Post Operation
Before leaving the crane unattended:
1 Land any load, bucket, lifting magnet or other device.
2 Put controls in the off or neutral position.
3 Disconnect and stow the control pendant.
The operator must be familiar with the equipment and its proper care. If adjustments or repairs
are necessary, the operator shall promptly report this to the appointed person and shall also
notify the next operator.
Overload Protection System
The crane is equipped with a system that, when activated by excess moment load, locks out the
hoist up, boom extend, and boom down functions. An overload condition is sensed as excess
pressure in the boom up hydraulic cylinder.
CAUTION
DO NOT HOIST OR EXTEND A LOAD WITH THE BOOM IN THE FULL DOWN POSITION.
To make sure that the overload protection system works properly, always raise the boom up off
the bottom of the cylinder before hoisting or extending the load. Failure to do this may result in a
crane overload condition with serious consequences. When the crane goes into overload mode,
the operator should relieve the overload by lowering the hoist or retracting the boom. The best
system for preventing overload is a well-trained, cautious crane operator. The overload
protection system should not be viewed as a substitute for sensible safety precautions, but
rather a backup system in case of operator error. Remember, when the overload system is
triggered, the crane is OVERLOADED. The pressure setting of the overload protection system
is factory set and should not be tampered with. If the operator is in doubt as to whether the
overload protection system is working properly, he should contact his supervisor immediately.
