PRE-OPERATION INSPECTION AND CALIBRATION VERIFICATION
Prior to operating the crane, the following electrical connections must be checked to ensure that the
system is properly connected for the crane configuration.
Machines with only a Main Hoist
If the crane works only with the boom and without boom extension or jib, no additional connections
are necessary. However, be sure the weight of the anti-two-block switch is properly installed on the
main hoist load line. With even parts of hoisting line, the weight shall be attached to the dead-end
line. With odd parts of hoisting line, the weight shall be attached to the line of lowest speed.
If the crane works with boom extension or jib, the connecting cable shall be installed between the
junction box on the boom extension or jib and the boom junction box. The weight attached to the
main hoist anti-two-block switch shall be removed. Then the weight shall be reattached to the boom
extension or jib anti-two-block switch.
WARNING
Failure to re-position the anti-two-block switch weight will prevent the overhoist system from func-
tioning properly. No weight shall be on the main hoist anti-two-block switch when the boom exten-
sion or jib is being used.
Machines with Main and Auxiliary Hoists
If the boom extension or jib is not in the operating position, the by-pass plug shall be installed in the
main boom junction box. The weight of the main hoist anti-two-block switch shall be installed.
If the boom extension or jib is in the operating position, the connecting cable shall be installed be-
tween the junction boxes on the boom extension or jib and the main boom. Weights shall also be
attached to the anti-two-block switches on both the main boom and boom extension or jib.
If the boom extension or jib is in the operating position and no load line is being used on main boom,
to prevent injury or damage to equipment, the weight shall be removed from main boom switch.
