REEVING BLOCKS. To reeve blocks in simple tackle, you must first lay the blocks a few feet apart. The blocks should be placed down with the sheaves at right angles to each other and the becket bends pointing toward each other. To start reeving, lead the standing part of the falls through one sheave of the block that has the greatest number of

To Determine Line Pull: Line Pull = 1,000 lbs. ÷ 2.00 = 500 lbs. The Reeving of Tackle Blocks In reeving of tackle blocks, there are many methods. The

Shorty “J” reeving guides reduce the time and effort required to reeve a block by guiding the line easily around each sheave. The feature is especially valuable in crane rental operations, or conditions in which the line parts of a block must be changed frequently.

A block is a set of pulleys or sheaves mounted on a single frame. An assembly of blocks with a rope threaded through the pulleys is called tackle. The process of threading ropes through blocks is called "reeving", and a threaded block and tackle is said to have been "rove". A block and tackle system amplifies the tension force in the rope to lift heavy loads.

There is more than one method of reeving the blocks, but the “right angle method” is preferred. With the right-angle method, the blocks are laid in such a way that the sheaves are at right angles to each other; this will reduce the chances of chafing of the rope or turning of the blocks. The main procedure for reeving the blocks follows: 1.

A block and tackle is an assembly of pulley blocks and rope or cables that are set up to decrease the effort needed to haul or hoist heavy loads. Each block has one or more pulley. Thread the rope, alternating between the pulley attached to the block on the object you want to move and the pulley attached to a fixed

Block Division has been a family owned and operated business since 1960. We were the first company to specialize in small pulleys, sheaves, and accessories, and for over 5 decades we’ve continued to be a leader in the industry. We manufacture consistently durable, …
