一、Introduction
The YJ1.5, YJ3, and YJ5 series hydraulic winches produced by our company are driven by low-speed high torque hydraulic motors to rotate the drum, and use steel wire ropes wrapped around the drum to lift and lower heavy objects. This series of hydraulic winches only requires users to equip a pump station and a directional valve to use. Due to its built-in valve group, it not only simplifies the hydraulic system but also improves the reliability of the transmission device. It successfully solved the technical problems of empty hook shaking and secondary sliding during lifting in general hydraulic winches. At the same time, it also has the characteristics of high start-up and working efficiency, low energy, low noise, compact size, beautiful appearance, and easy installation. It can be widely used in various lifting equipment such as oilfield drilling and production, ships, truck cranes, coal mines, ports, etc.
二、Product Description
ST series hydraulic winch is composed of cycloid motor, planetary gear reducer, brake and so on. Which can be widely used in all kinds of lifting equipment, such as railway locomotive and truck crane, ship, oil field drilling, coal mine, port, small engineering machinery and so on. This hydraulic winch is a lifting equipment driven and braked by hydraulic. It has the advantages of compact structure, light weight, convenient operation and stable lifting. It is used to lift heavy objects in drilling, mines, ports and building engineering.
Model YJ1.5, YJ3, YJ5 hydraulic winches are drove by low speed and big toque hydraulic motor and can be stopped hydraulic control brake.Main components are assembled with originally imported equipments. The surface of winch is treated with special technical process, good-outlook,compact structure and convenient installation. Model YJ5 is the patent of Litian Transmission Co. Ltd. It is used widely when dragging heavy goods and lifting work in petroleum, coal mine, railway, mining engineering, shipment, harbor and architecture engineering and so on.
