About Us

Our company is a specialized manufacturer for crane spare parts and accessories, such as pulleys and pulley blocks of various types as well as spare parts for cantilevered maintenance cranes. At present, we produce hot-pressing pulleys (from dia. 280 mm up to dia.1800 mm).Our pulley products are widely used in various applications, such as crane loading and floating gantry, as well as various sectors such as metallurgical and chemical industries, mining machineries and construction installation engineering, etc.

Our products, characterized by reasonable structure, high strength, light weight, high precision and high anti-wear performance because of heat treatment process for the surface of rope race, are expanding its application scope and are gradually replacing cast iron pulleys whose quality is not stable with high pollution and energy consumption.
