Reeving and Anchorage

6.6.1

Reeving the bottom block

Use a pliers to hold the rope securely.

1. The hoist must be energized in order to complete the reeving of the rope. Take extreme caution

while performing this operation.

2. Lay out the end of the rope that is not wound on the drum. Let this end hang freely.

3. Make certain that the wire rope lies snuggly on the rope drum. Avoid wire rope slack at all times.

Slack will cause premature rope guide wear as well wire rope wear.

4. Make paint mark on side of the wire rope. This mark will assist in detecting the presence of rope

twist.

5. Reeve the end of the rope into the rope sheaves of the bottom block and return pulleys. (

Figure 6-16

and

6-17

)

Do not allow rope to twist.

7. Place rope around rope wedge (2) and pull it into the tapered rope recess (1) until the loose end of the rope

projects approx. 100mm.

8. Secure loose end of rope with rope clamp (3) approx. 50mm from the end of the rope. See Table 6-2 for

torque specification.

9. Verify the maximum projection of the rope wedge “x” dimension. (See

Figure 6-17

and

Table 6-1

).

10. Reinstall rope recess assembly according to the anchorage configuration determined by the hoist model.
