Product description

Type ZHC marine pulley is a lifting product designed and developed for offshore operation. The reinforced guard plate and special sealing device greatly improve the impact resistance and corrosion resistance of the pulley. It is much better than ordinary lifting pulley, suitable for lifting operation in port and ocean conditions.
In view of the characteristics of corrosion resistance and impact resistance required by the ship wharf industry, two technologies, namely reinforced guard plate and special sealing device, are adopted to enhance the impact resistance ability of the pulley itself and greatly improve the safety of hoisting and towing.
