Can be designed to electric or hydraulic winch, single drum or double drum,multiple drum according to customer's needs. Electric mooring winch is widely used in the place with heavy work and big traction.the motor of the single drum winch drive the drum by reducer box,the brake is installed between the motor and input shaft. electric mooring winch could be set up to single drum, double drum and multiple drum for adapting the needs of hoisting, traction and rotary work. Normally,winch with the rated load less than 10ton could be set up to electric mooring winch. Hydraulic mooring winch is the winch with the rated load from 10T~5000T, hydraulic motor have high mechancial efficiency and large torque, can drive different distributor as per different working conditions. this kind of winches have following features:compact structure,small size,light,nice appearance,safty,high efficiency,large torque,good stability,low noise,reliable operation and so on. |
Types of winch
According to the power winch is divided into manual, electric, hydraulic three types.
According to the function of winch can be divided into: Marine winch, engineering winch, mining winch, cable winch and so on.
Marine winch can be divided into: mooring winch, positioning winch, towing cable winch, anchor winch and so on.
According to the drum form is divided into single drum and double drum.
According to the drum distribution form is divided into parallel double drum and double drum before and after.
Manual winch
Stoppers (ratchets and pawl) are mounted on the transmission mechanism with the handle of the manual winch to keep the weight in the desired position. Manual winches for assembling or lifting heavy objects shall also be provided with safety handles and brakes. Manual winch is generally used in small lifting weight, poor facility conditions or no power supply.
Electric winch
Electric winch is widely used in heavy work and large traction required. The motor of the single-drum electric winch drives the drum through the reducer, and a brake is arranged between the motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotary operations, there are double - and multi-reel winches. Generally winches with rated loads below 10T can be designed as electric winches [1].
Hydraulic winch
Hydraulic winch is mainly rated load larger winch, under normal circumstances more than 10T to 5000T winch design hydraulic winch.
Its structure is mainly composed of hydraulic motor (low speed or high speed motor), hydraulic normally closed multi-disc brake, planetary gear box, clutch (optional), drum, supporting shaft, frame, rope press (optional) and so on. Hydraulic motor has high mechanical efficiency, large starting torque, and can request according to the working condition of flow distribution with different, also can design according to customer's need valve group directly integrated in the motor oil distribution, such as belt balance valve, the overload valve, shuttle valve, high pressure control reversing valve or other performance of the valve group, brake, planetary gear box installed directly in the drum, Drum, support shaft, frame design according to mechanical requirements, the overall structure is simple and reasonable and has enough strength and rigidity. Therefore, this series winch has the characteristics of compact structure, small size, light weight and beautiful appearance, and has the characteristics of good safety, high efficiency, large starting torque, good low-speed stability, low noise and reliable operation in performance. It is worth mentioning that the high volume efficiency of the hydraulic motor and the high quality balance valve of SUN Company in the United States solve the second slide and empty hook jitter phenomenon of the general winch, so that the series of hydraulic winch lifting, lowering and braking process is smooth, with the clutch winch can also realize free lowering. The integrated valve assembly mounted on the valve plate simplifies the hydraulic system. Because this series of winches have the advantages mentioned above, so that it is widely used in shipping, railway, construction machinery, petroleum, geological exploration, metallurgy and other industries, its excellent performance has been recognized by users.
