Stabilizer Operation
Stabilizers help stabilize the crane and carrier vehicle during a lift, but they can be hazardous
due to their close proximity to the operator and other personnel. They are the only component of
the crane which normally contact the ground.
WARNING
Stabilizers can cause serious injury!
Avoid stabilizer injuries including:
1
Hitting people while moving out.
2
Crushing people or equipment when contacting the ground.
3
Pinching people when being retracted.
There are various stabilizer designs available, but all require extreme caution in their use. See
figures for proper stabilizer operation sequence and warnings.
