Platform Or Boom Caught Overhead Or Boom Movement Prevented By Boom Control System; Emergency Towing Procedures - JLG 1250AJP Operation And Safety Manual

SECTION 5 - EMERGENCY PROCEDURES
Platform or Boom Caught Overhead or Boom Movement
Prevented by Boom Control System
Lowering the boom onto an object or structure may cause the
boom control system to prevent movement of the machine. This
can include movement necessary to lift the boom off the object.
Additionally, if the platform or boom becomes jammed or
snagged in overhead structures, movement of the boom can be
regained by doing the following:
1. Shut off the machine.
2. Rescue all people in the platform before freeing the
machine. Personnel must be out of the platform before
operating any controls on the machine.
3. Use cranes, forklifts, or other equipment to stabilize motion
of the machine to prevent a tip over as required.
4. From the ground controls, use the Auxiliary Power System to
carefully free the platform or boom from the object.
5. Once clear, restart the machine and return the platform to a
safe position.
6. Inspect the machine for damage. If the machine is damaged
or does not operate properly, turn off the machine immedi-
ately. Report the problem to the proper maintenance per-
sonnel. Do not operate the machine until it is declared safe
for operation.
