4 Pre-Operational Inspection
Prior to operating the crane, the following electrical connections must be checked to ensure that the
system is properly connected for the crane configuration.
4.1 Anti two-block devices
If the crane works only with the main boom and without boom extension, check the weight to ensure it is
attached to the anti two-block switch on the main hoist load line.
Weight installation - The hoist line runs through the A2B weight. 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 an extension exists, install the connecting cables between the boom extension junction box and the
boom point junction box. Remove the weight from the main boom anti-two block switch and re-attach it to
the boom extension anti-two block switch on the auxiliary hoist line.
Failure to position the anti two-block switch weight will prevent the overhoist system from functioning
properly. No weight shall be on the main hoist anti two-block switch when the boom extension is being
used.
