A Spur Gear Chain Pulley Block is basically designed to lift different kinds of heavy loads and bulk materials at the installed runways. Spur gears are a cylindrical shaped toothed component used in industrial equipment to transfer mechanical motion as well as control speed, power, and torque. The chain pulley block contains two wheels that have chains wound around them, and it is a mechanism used to lift and lower heavy loads. When the chains are pulled, they wind around the wheel and pull the object attached to the rope via hook. Spur Gear Chain Pulley Block is very effective.
