The design of wear plates, made of top-quality copper alloy and composite materials, allows for good wear resistance and greater heat dissipation characteristics. It is designed to accommodate open or closed cooling system. This product is mainly used for auxiliary braking for drawworks of oil drilling rig and workover rig.
