Function: Designed for hanging weight things to lighten load.
Applications: Widely used in tractive effort of steel wire rope or other rope tools. A rope, cable, belt, or chain usually runs over the wheel and inside the groove, if present.
Specification: Size: M20; Runner Diameter: 20mm; Wheel Width: 8mm; Rotating Ring Width: 13mm; Total Length: 74mm; Max Load: 75kg
Note: The max load weight is a Theoretical value, we cannot guarantee the pulley can achieved the max load,but these pulleys were standard made. Manual measurement, please allow 1-2mm error.
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.
