CONTROLS AND OPERATION
REEVING
Reeving diagrams for the main hoist line are shown in
Figure 2-14. The number of parts of line (from one to
seven) used in reeving the main hoist line will depend on
the load to be lifted. Refer to the rating chart in the upper
cab to determine reeving requirements for various loads.
Hoisting and lowering speeds decrease as the number of
parts of line increases.
When practical, use the
minimum number of parts required for the loads to be
lifted.
