Product Summary

3-wheel pulley block is a pulley block which has 3 wheels. A pulley block has a body that rotatably supports a sheave, the block having a mounting pin which extends through a bore in the block.

A pulley block is a main component of a pulley mechanism. It functions as the weight-bearing point in the system, which makes the work to be done substantially easier. Pulley blocks, though the name evokes an image of a square, are actually the grooved circles in pulley systems that are used to guide the rope or cable through the pulley. A pulley block is, in fact, the essential component of the pulley system.
