TWO-PART LINE REEVING
For loads above 2500 pounds (1135 kg) the sheave block must be used. The wedge
socket should be pinned to the 2-part line lug, as shown in the figure. The dead end of
the rope in the wedge socket should be clamped, as shown in the figure. The clamp
must not be used on the live part of the rope. This will seriously weaken the rope by
metal fatigue over a number of cycles. The sheave block should hang straight, and the
top of the block should meet the boom sheave plates squarely when pulled up snugly.
