MULTI-PART LINE REEVING
For loads above 9000 pounds (4080kg) the sheave block must be used. The four-part-line
sheave block can be used for loads up to 36,000 pounds (16330kg). The optional two-part-
line sheave block can be used for loads up to 18,000 pounds (8160kg). The wedge socket
should be pinned to the wedge socket anchor, 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. The sheave
block
should hang straight, and the top of the block should meet the boom sheave plates
squarely when pulled up snugly.
