Stay in the crane until the power source has been deenergized.
Only as a Last Resort should an operator attempt to leave the crane upon
contacting a power source.
If it is absolutely necessary to leave the operator station, JUMP COMPLETELY
CLEAR OF THE CRANE - DO NOT STEP OFF. Hop away with both feet
together. DO NOT walk or run.
When operating cranes equipped with electromagnets you must take additional
- Permit no one to touch the magnet or load.
- Alert personnel by sounding a warning signal when moving a load.
- Do not allow the cover of the electromagnet power supply to be open
during operation or at any time the electrical system is activated.
- Shut down the crane completely and open magnet control switch
prior to connecting or disconnecting magnet leads.
- Use only a nonconductive device when positioning a load.
- Lower magnet to stowing area and shut off power BEFORE leaving
the operator's cab.
Following any contact with an energized electrical source, thoroughly inspect
the wire rope and all points of contact with the crane.
Advise your distributor on the incident and consult the factory for advice and
crane inspection instructions prior to resuming operations.
H E A R I N G PROTECTION REQUIRED.
Scamp test results have indicated steady state nose levels of 85dB(A) and
g r e a t e r , at governed engine rpm, during crane swing function. The
maximum level of 87.5dB(A) occurs at the operator's station in the open or
closed cab and decreases to 85dB(A) at the envelope contour shown in
Figure 2-1. Outside this contour the level
is below 85dB(A).
