TM 10-3950-672-10
Be sure the hoist line is vertical before starting the lift. Don't subject the crane to side loadings.
Measure the load radius before making lifts and stay within approved lifting areas. Check your load chart!
The importance of properly leveling a crane cannot be overstressed. A crane only slightly out of-level can quickly
encounter a tipping condition.
Barricade the area around which the crane is working.
Don't interfere with the proper functioning of operational aids or warning devices. Monitor them regularly and see they
get the proper care.
Always refer to the capacity on the load chart in the cab BEFORE making any lift. Position the hoist line to the radius
required then lift the load. Stay within the approved work area for the load being lifted.
Remember all rigging equipment must be considered as part of the load. Lifting capacities vary with working area.
Permissible working areas are posted in the crane cab. When swinging from one working area to another, ensure load
chart capacities are not exceeded. Know your crane!
Operate the engine at or near governed RPM during performance of all crane operations.
Do not exceed crane rating. Do not rely on the crane tipping stability to determine the maximum lifting capacity. Do not
exceed the capacities shown on the load chart in the cab. REMEMBER: ALL LIFTING DEVICES (HEADACHE BALL,
BLOCK, JIB, ETC.) ARE PART OF THE LOAD.
Always check the capacity of the crane as shown on the load chart before making any lifts.
Know the weight of all loads before you attempt a lift. Ensure the load to be lifted is within the rated lifting capacity of the
crane.
Always keep the load as near to the crane and as close to the ground as possible.
NEVER exceed the rated lift capacity shown on the load chart. Always check the load chart to ensure the load to be
lifted at the desired radius is within the rated capacity of the crane.
NEVER use the crane stability to determine capacity. It may be too late when you find out.
Multiple crane lifts are not recommended. The use of more than one crane to make a lift requires the ultimate in
equipment, engineering, operating skill, and lift coordination.
BUT, if it is necessary to perform a multi-crane lift, the operator shall be responsible for assuring that the following
minimum safety precautions are taken.
1. Secure the services of a qualified engineer to direct operation.
2. Use one signal person and be sure he is qualified.
