Industrial pulleys are used as integral part of heavy duty machines, ships and marine equipments for controlling pulling or lifting force of different machines. This array of pulleys has been designed to handle various types of load. Lifting or pulling speed of these pulleys varies as per their design. Axial grooves of these pulleys play significant role in minimizing friction during their movement. Industrial pulleys with high torque transmission based design are suitable for power transmission job. High wedge contact of this array of pulleys minimizes their possibility of slippage.
