HCSD-160-19.7-300-250-36-650-Z-HA50 Cutter Suction Dredger Hydraulic Ladder Winch With a high output torque cam-ring piston motor(84010452.0:30T)

Cutter suction dredgers (CSDs) rely on a complete hydraulic winch system to perform precision excavation, position keeping and on-board maintenance. Among them, the hydraulic ladder winch and hydraulic hoisting winch are two core functional units: the ladder winch acts as the executive mechanism for dredging depth control, while the hoisting winch supports auxiliary lifting and maintenance operations. Both are engineered for heavy-duty, long-cycle operation in abrasive, high-humidity and salt-spray dredging environments, and directly determine the operational efficiency, construction accuracy and site safety of CSD projects.
