Advise your supervisor of the incident, who should
consult TACOM for advice and crane inspection
instructions prior to resuming operations.
Do not strike anything with the boom. If the boom should
contacts an object; stop immediately. Inspect the boom.
Do not use the crane if the boom is damaged.
Never push or pull something with the boom.
Do not add weight to counterweight to increase the
Cranes are 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.
Never pull sideways with boom. Booms and swing
systems are not designed to side pull and may be
damaged from side loading. Booms are designed for
lifting only freely suspended loads.
LIFT ONE LOAD AT A TIME. Do not lift two or more
separately rigged loads at one time, even if loads are
within the rated crane capacity.
PLANNING AND SET UP
Review the safety precautions in previous section.
Study the job site and select best location for the
crane, where the:
Surface is solid,
Surface is level as possible,
Crane is as far away from electrical power
sources, overhead power lines, etc., as possible,
Crane is sheltered from wind. (Be cautious if
wind speed approaches 20 mph.)
Know weight of all loads before you attempt a lift.
Ensure load to be lifted is within rated lifting capacity
of the crane.
Remember - all rigging equipment must be
considered as part of load.
Measure load radius before making lifts and stay
within approved lifting areas. Check your load chart.
Permissible working areas are posted in crane cab.
When swinging from one working area to another,
ensure load chart capacities are not exceeded.
Know your crane!
When lifting loads, crane will lean toward boom and
load will swing out, increasing load radius. Ensure
load capacity chart is not exceeded when this
Always keep the load as near to the crane and as
close to the ground as possible.
Position crane and extend outrigger beams.
Place cribbing on ground and position floats under
jack cylinders at four places. Use cribbing under
outrigger floats to distribute weight over a greater
area. Check frequently for settling.
Extend jack cylinders and latch cylinder ends to
