QUALIFICATIONS FOR AND CONDUCT OF OPERATORS AND OPERATING PRACTICES
or neutral position and all personnel are in the clear.
If power fails during operation, the operator shall:
Move power controls to the "OFF" or neutral position.
Land the suspended load and boom, if practical.
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 person, and shall also notify the next operator.
The operator at the start of each shift shall test all controls. If any controls do not operate properly, they shall be adjusted or repaired before operations are begun.
Stabilizers shall be visible to the operator while extending or setting unless a signal person assists operator.
OPERATING PRACTICES/HANDLING THE LOAD
Size of load.
No crane shall be loaded beyond the rated load except for test purposes.
The load to be lifted is to be within the rated load of the crane and its existing configuration.
When loads that are not accurately known are to be lifted, the person responsible for the job shall ascertain that the weight of the load does not exceed the crane rated load at the radius at which the load is to be lifted.
Attaching the load.
The load shall be attached to the hook by means of slings or other devices of sufficient capacity.
Hoist rope shall not be wrapped around the load.
Moving the load. The operator shall determine that:
The crane is level and, where necessary, the vehicle/carrier is blocked properly.
The load is well secured and balanced in the sling or lifting device before it is lifted more than a few inches.
Means are provided to hold the vehicle stationary while operating the crane.
Before starting to lift, the hook shall be positioned over the load in such a manner as to minimize swinging.
During lifting care shall be taken that:
There is no sudden acceleration or deceleration of the moving load.
Load, boom or other parts of the crane do not contact any obstruction.
Cranes shall not be used for dragging loads sideways.
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. Crane manufacturer must approve work platforms attached to the boom.
The operator should avoid carrying loads over people.
When the crane is so equipped, the stabilizers shall be fully extended and set. Blocking under stabilizers shall meet the requirements as follows:
Strong enough to prevent crushing.
Of such thickness, width and length as to completely support the stabilizer pad.
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.
In transit, the boom shall be carried in stowed position.
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.
The crane shall not be transported with a load on the hook unless recommended by the manufacturer.
