A Crane Pulley Block is a kind of hoisting tool, also called a sheave, is a mechanism composed of a wheel on an axle or shaft that may have a groove between two flanges around its circumference.
A rope, cable, belt, or chain usually runs over the wheel and inside the groove, if present.
Pulleys are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion.

Function: Designed for hanging weight things to lighten load.
Advantage: Durable, strong, reliable, waterproof, anti-rust, anti-high temperature, corrosion resistance.
Applications: Widely used in tractive effort of steel wire rope or other rope tools.
