5. Before closing the switch or starting the engine, the operator shall see that all controls are in the "OFF" or neutral
position and all personnel are in the clear.
6. If power fails during operation, the operator shall:
A. Move power controls to the "OFF" or neutral position.
B. Land the suspended load and boom, if practical.
7. The operator shall be familiar with the equipment and its proper care. If adjustments or repairs are necessary, the
operator shall report the same promptly to the appointed per-son, and shall also notify the next operator.

4.5 OPERATING PRACTICES/HANDLING THE
Never use two cranes to support a load too large for either crane.
1. Size of load.
A. No crane shall be loaded beyond the rated load except for test purposes
B. The load to be lifted is to be within the rated load of the crane and its existing configuration.
C. Know the weight of the rigging and deduct from the load rating to prevent overloading the crane.
D. When loads that are not accurately known are to be lifted, the person responsible for the job shall
determine the weight of the load does not exceed the crane rated load at the radius at which the load is to
be lifted.
2. Attaching the load.
A. Ensure the load is properly attached to the hook by means of slings or other devices of sufficient capacity.
B. Ensure the vehicle is in a level position when loading or unloading.
C. Hoist rope shall not be wrapped around the load.
3. The operator shall determine that:
A. The crane is level and, where necessary, the vehicle/carrier is blocked properly.
B. The load is well secured and balanced in the sling or lifting device before it is lifted more than a few
inches.
C. Means are provided to hold the vehicle stationary while operating the crane.
D. Before starting to lift, the hook shall be positioned over the load in such a manner as to minimize
swinging.
4. During lifting care shall be taken that:
A.
There is no sudden acceleration or deceleration of the moving load.
B. When rotating the crane, sudden starts and stops shall be avoided. Rotational speed shall be such that
the load does not swing out beyond the radius at which it can be controlled.
C. Load, boom or other parts of the crane do not contact any obstruction.
D. Cranes shall not be used for dragging loads sideways.
E. This standard recognizes that telescopic boom cranes are designed and intended for handling materials.
They do not meet personnel lift or elevator requirements. Therefore, no lifting, lowering, swinging or
traveling shall be done while a person is on the hook or load. Hook attached suspended work platforms
(baskets) shall not be used with cranes covered by this standard.
F. The operator should avoid carrying loads over people.
5. When the crane is so equipped, the stabilizers shall be fully extended and set. Blocking under stabilizers shall
meet the requirements as follows:
A. Strong enough to prevent crushing.
B. Of such thickness, width and length as to completely support the stabilizer pad.
C. Firm footing under all tires, or individual stabilizer pads should be level. Where such a footing is not
otherwise supplied, timbers, cribbing, or other structural members to distribute the load so as to not
exceed allowable bearing capacity or the underlying material should provide it.
6. In transit, the boom shall be carried in stowed position.
7. The crane shall not be transported with a load on the hook.
