Operating Practices/Handling The Load
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.

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. ASME B30.5 recognizes that mobile and locomotive cranes are designed and intended for handling
materials and not generally personnel. However, personnel are permitted to ride in an Auto Crane
authorized, boom-mounted, personnel platform when used in accordance with the requirements of
ASME B30.23 and Auto Crane’s instructions. The crane shall not be used for other purposes while
!
