Bridge Pulley Block

커터 흡입 준설선의 동력 전달 시스템에서 풀리 블록은 주요 힘 전달 및 방향 전환 장치 역할을 합니다. 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.
