TM 5-3810-302-10
When lifting loads, lift slowly and proceed with caution.
Maintaining a steady tension may free the load without shock loading the
crane.
Cranes are designed and rated to handle freely suspended loads. Do not pull
post, piling, or submerged articles that may have a heavy accumulation of
mud, silt, or sand.
When lifting loads, the crane will lean toward the boom and the load will
swing out, increasing load radius. Ensure the load capacity chart is not exceeded
when this happens.
Check the swing brake. Make certain the swing brake operates correctly.
Unexpected free swinging of a boom can be dangerous.
Wind and other factors such as boom length, boom angle, size and weight of
load being lifted, etc. can affect crane stability and crane structures. Practical
working loads for each particular job and lift shall be established by the user
depending upon conditions that exist at the time a lift is being made. Appro-
priate capacity reductions shall be made whenever conditions indicate the
possibility that a loss of crane stability or structural damage could occur. Be
extremely cautious if wind velocity approaches 20 miles per hour.
