MULTI-PART LINE REEVING
For loads above 7500 pounds (3400 kg) the sheave block must be used. The 4-part-line
sheave block can be used for loads up to 30,000 pounds. The optional 2-part-line sheave
block can be used for loads up to 15,000 pounds. 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 figures.
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.
