In many underwater dredging and construction process in order to ensure the patency of the river and security, will be on underwater debris salvage work, clean up the whole river. Underwater salvage process, the winch is one of the commonly used equipment, it can play a level of debris dragged underwater salvage role. Here's an overview of the structural characteristics of the underwater salvage winch.
The structure consists of a hydraulic motor (low or high speed motor), normally closed hydraulic multi-plate brake, planetary gearbox, clutch (optional), reel support shaft, rack, press rope (optional) and so on. Hydraulic motor with high mechanical efficiency, starting torque, and in accordance with the requirements of different operating conditions with converters, also based on user needs and design valve with integrated directly on the motor oil. The overall structure is simple and reasonable and has sufficient strength and rigidity. Thus the series winch on a compact structure, small size, light weight, appearance and other characteristics, the performance will have good security, high efficiency, starting torque, low-speed stability, low noise, reliable operation.\
