marineusedgood offer various electric winches, pneumatic winches, hydraulic winches, manual winches.
A winch, also known as a hoist, is a light and small lifting device that uses a drum to wind a steel rope or chain to lift or tow heavy objects. The winch can be used alone or as a component in machinery such as lifting, road building, and mine hoisting. It is widely used due to its simple operation, large amount of rope, and easy displacement. Mainly used for material lifting or leveling of construction, water conservancy projects, forestry, mines, docks, etc.
The winches can be divided into four types: manual winches, electric winches, pneumatic winches, and hydraulic winches according to their different methods of use. At present, the ship's hydraulic winch is 350T, and the weight of the equipment reaches 150T.
According to the reel form, it is divided into single reel and double reel.
According to the roll distribution form, it is divided into parallel double rolls and front and rear double rolls. The main technical indicators of hydraulic winches are rated load, support load, rope speed, rope capacity, etc.
The winch is divided into three categories according to power: manual, electric and hydraulic.
A stopper (ratchet and pawl) is installed on the turning mechanism of the handle of the manual winch to keep the weight in the required position. Manual winches for assembling or lifting heavy objects shall also be provided with safety handles and brakes. Manual winches are generally used in places with small lifting capacity, poor installation conditions or no power supply.
Electric winches are widely used in places with heavy work and large traction. The electric motor of the single drum electric winch (pictured) drives the drum through the reducer, and a brake is installed between the motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and turning operations, there are also winches with double and multiple reel devices. Generally, winches with a rated load below 10T can be designed as electric winches.
Hydraulic winches are mainly winches with large rated load. Generally, winches above 10T to 5000T are designed as hydraulic winches.
It can be customized as request with certification.
