Introduction:

The winch is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. The winch can lift heavy objects vertically, horizontally, or obliquely. There are three types of winches: manual winches, electric winches, and hydraulic winches, mainly based on electric winches. Usually, it could use alone or as a component in types of machinery such as lifting, road construction, and mine hoisting. It uses widely because of its simple operation, lots of rope winding, and convenient displacement. Usually, it uses mainly for material lifting or flat dragging in construction, water conservancy projects, forestry, mines, docks, etc.

Classification standard of winch:

  • According to the reel form, it is divided into a single reel and a double reel.
  • According to the distribution form of the reels, it divides into parallel double reels and front and rear-double reels.
  • The winch is divided into manual, electric and hydraulic, according to the power.​​

    The transmission mechanism of the handle rotation of the manual winch equips with a stopper (ratchet and pawl), which can keep the weight in the required position. Manual winches for assembling or lifting heavy objects should also equip with safety handles and brakes. Manual winches use in general in places with small lifting capacity, poor facilities, or no power supply.​​

    Electric winches are used widely in places where the work is heavy and requires a large of traction. Due to the need for lifting, pull, and turning operations, electric winches can also be designed to equip with double-drum and multi-drum devices. A winch with a generally rated load below 10T can choose an electric winch.​​

    Hydraulic winches are mainly winches with more large rated load. Generally, winches from 10T to 5000T would design as hydraulic winches.

    • Winches can divide into marine winches, engineering winches, and mining winches, according to the operational environment.

    Which winches are marine? Generally, it includes towing winches, mooring winches, anchor winches, traction winches, etc.

    Engineering winch: mainly used in engineering with functions such as hoisting and lifting.​​

    Mining winches: divided into hoisting winches, dispatching winches, sinking winches, return column winches, mining winches, return-column winches, etc.

    Winch selection method

    Speed selection

    Generally, for the construction and installation projects with the short lifting distance and high accuracy requirements, slow-speed winches should use. For long-distance lifting or traction objects and to improve productivity and reduce power consumption, a fast-speed winch should use.

    Selection of the number of cylinders

    In general, single-cylinder winches use in construction because of their simple structure, easy operation, and movement. If the bucket truck is towed back and forth on double-track tracks, double-cylinder winches should be in use to simplify installation work, reduce operators, and improve productivity.

    Transmission form selection

    Due to the small body, compact structure, lightweight, flexible operation, and easy operation, the winch, driven by the planetary type and planetary pin gear reducer, is very suitable for construction and can be chosen as a priority.

    Power selection

    Due to the safe and reliable operation of electric machinery, low operating cost, and remote control, electric winches should use wherever there is a power supply. If there is no power supply, hand winches or internal combustion winches could be in consideration according to the situation.
