According to different methods of use, winches can be divided into four types: manual winches, electric winches, pneumatic winches, and hydraulic winches. At present, the largest marine hydraulic winch is 350T, and the weight of the equipment reaches 150T.

In the international market, the London Metal Exchange (LME) nickel rose 0.54% on Monday.
At the end of last year, Chinese nickel consumers hoarded a large amount of raw material stocks, which could support six months of production activities, in response to the Indonesian ban on unprocessed laterite nickel ore.
But as time went by, these inventories were gradually consumed, and some Chinese producers began to cut production to counter the supply of raw materials.
Analysts from industry-leading research firm Antaike and my steel network said that the current situation indicates that the supply of nickel ore in the domestic market is tight.
In the spot market, spot sellers are reluctant to sell, and traders profit from speculation. As a result, nickel prices continue to rise.
China's nickel ore imports totaled 2.29 million tons in March, down 35.9% from the previous month, of which 900,000 tons came from Indonesia and 1.31 million tons came from the Philippines.
China's nickel-iron imports in March fell 33.6% from the previous month to 17,800 tons.
Analysts at Morgan Stanley said recently that they are optimistic about the mid- and long-term performance of nickel prices. However, it is worried about the recent surge in nickel prices.
According to the reel form, it is divided into single reel and double reel.
According to the reel distribution, there are parallel double reels and front and rear double reels.
The main technical indicators of hydraulic winches include rated load, supporting load, rope speed, rope capacity, etc.
A winch is a light and small lifting device (see hoisting machinery) that uses a reel to wind a wire rope or chain to lift or tow heavy objects, also known as a hoist. The winch can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding volume and convenient displacement. The winch is also known as the hoist. The product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient transfer. It is widely used in construction, water conservancy projects, forestry, mines, docks, etc. for material lifting or flat towing, and can also be used as modern electronic control Supporting equipment for automatic operation line.
According to the power, the winch is divided into three categories: manual, electric and hydraulic.
The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet wheel and pawl), which can keep the heavy object in the required position. The manual winch used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used in places where the lifting capacity is small, the facilities are poor, or where there is no power supply.
Electric winches are widely used in places with heavy work and large traction requirements. The electric motor of the single-drum electric winch (pictured) drives the drum through the reducer, and a brake is installed between the electric motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotation, there are also double-drum and multi-drum winches. Generally, a winch with a rated load lower than 10T can be designed as an electric winch.
The hydraulic winch is mainly a winch with a larger rated load. Generally, the winch from 10T to 5000T is designed as a hydraulic winch. The winch can be divided into:
Marine winches: Marine winches can be divided into drag winches, mooring winches, anchor winches, traction winches, etc.
Engineering winch: Mainly used in engineering, with functions such as hoisting and hoisting as the main function.
Mine winches: divided into hoisting winches, dispatching winches, shaft sinking winches, column return winches, rake mine winches, column return winches, etc.
Cable winch: mainly used when laying cables.
