Bridge Pulley Block

In the power transmission system of a cutter suction dredger, the pulley block serves as a key force transmission and direction conversion device. It performs the crucial tasks of guiding the cable and adjusting its tension, providing stable and reliable power transmission for the cutter suction dredger and becoming a critical component for its operational precision and efficiency.

This pulley block utilizes the composite pulley principle to create a multi-stage transmission system, achieving efficient power transmission through an optimized pulley arrangement. Compared to traditional pulley systems, this new generation offers significant advantages: transmission efficiency is increased to 98%, resulting in 15% energy savings compared to conventional pulleys. Its compact design reduces weight by 30%, making it more suitable for the layout of large cutter suction dredgers.

This pulley block has been successfully used in various dredging environments: in deep-sea operations, its corrosion resistance supports operations in water depths of 50 meters; in river regulation projects, its exceptional wear resistance withstands harsh conditions with sand content as high as 35%; and in polar dredging, its low-temperature special steel ensures reliable operation in temperatures as low as -40°C.
