Quick Reeving the Hook Block
To quick reeve the hook block without removing the wedge
socket on end of hoist rope, remove the retaining clips from
the two pins (1, Figure 5-24), then lower the two rope guards
(2) to their lowered positions.
Reeving Hoist Rope Over the Boom
Always reeve main hoist rope through rope guide
(1, Figure 5-25). Always reeve auxiliary hoist rope outside of
the rope guide.
Adjusting the Upper Head Sheave
Use the following procedure to adjust the right head sheave
(1, Figure 5-26) on the boom tip. Adjusting the upper head
sheave aligns the hoist rope with the second inner sheave on
the lower sheave head. The required position of the head
sheave depends on the reeving configuration.
NOTE: The left upper sheave head used for the auxiliary
hoist rope cannot be adjusted.
1. Remove the retaining clip and rod (2).
2. Turn and remove the lever (3) from the cutout (4 or 5).
3. Push the head sheave (1) into the required position.
4. Turn the lever (3) in to the cutout (4 or 5).
5. Insert the rod (2). Secure the rod with the retaining clip.
CAUTION
Reeve only the main hoist rope through the rope guide.
Do not reeve the auxiliary rope through the rope guide.
Never reeve multiple ropes through the rope guide at the
same time. Rope damage can occur.
