Hydraulic winch middling coal hydraulic winch manufacturer Shandong hydraulic winch with large quantity is preferred

Description :

　　A winch is a light and small lifting equipment (see lifting machinery) that uses a drum to wrap steel wire rope or chain to lift or pull heavy objects, also known as a hoist. Hydraulic winches are mainly winches with high rated loads. Generally, winches ranging from 10T to 5000T are designed as hydraulic winches. Our company mainly produces and sells hydraulic winches for ships.

　　Marine winches: Marine winches can be divided into towing winches, mooring winches, anchor winches, traction winches, etc.

　　Widely used for material lifting or flat towing in marine engineering, construction, water conservancy engineering, forestry, mining, docks, etc.

　　Hydraulic winches are mainly winches with high rated loads. Generally, winches ranging from 10T to 5000T are designed as hydraulic winches.

　　Hydraulic winch structure

　　Mainly composed of hydraulic motor (low-speed or high-speed motor), hydraulic normally closed multi disc brake, planetary gearbox, clutch (optional), drum, support shaft, frame, rope press (optional), etc. Hydraulic motors have high mechanical efficiency, large starting torque, and can be equipped with different distributors according to working conditions. They can also be designed with valve groups directly integrated into the motor oil distributor as needed, such as balance valves, overload valves, high-pressure shuttle valves, speed control directional valves, or other performance valve groups. Brakes, planetary gearboxes, etc. are directly installed in the drum. The drum, support shaft, and frame are designed according to mechanical requirements, and the overall structure is simple and reasonable with sufficient strength and rigidity. Therefore, this series of winches has the characteristics of compact structure, small volume, light weight, and beautiful appearance. In terms of performance, it has the characteristics of high starting torque, high efficiency, good low-speed stability, low noise, and reliable operation.

　　Working principle of hydraulic transmission

　　Using oil as the working medium, motion is transmitted through changes in sealing volume, and power is transmitted through the pressure inside the oil.

　　1. Power section - converts the mechanical energy of the prime mover into hydraulic pressure energy, such as hydraulic pumps.

　　2. Execution section - Convert the hydraulic pressure input from the hydraulic pump into mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor.

　　3. Control section - used to control and regulate the pressure, flow rate, and flow direction of oil, such as pressure control valves, flow control valves, and directional control valves.

　　4. Auxiliary part - Connect the first three parts together to form a system that serves functions such as oil storage, filtration, measurement, and sealing. For example, pipelines and fittings, fuel tanks, filters, accumulators, seals, and control instruments.
