Test or Inspection
CRANE DOES NOT OPERATE WITH REMOTE CONTROL UNIT.
Step 1. Ensure that the EMERGENCY STOP switch (1) on the crane remote control unit (2) is in the
ON position. This switch disables all crane functions when in the OFF position.
If the switch is in the OFF position, raise cover and move switch to ON position.
If the switch is in the ON position, go to Step 2.
Step 2. Check electrical connections at the remote control unit (2) and at the crane (3). Inspect
connector (both the crane, remote control unit and harness side) for damage; bent,
corroded, and unseated pins and sockets.
If damaged connections were found, notify Unit Maintenance.
If no damage is found, go to Step 3.
