Compact Double Drum Electric Winch , 50 Ton Winch Grooved Drums For Oil Mining

Double Or Four Lebus Grooved Drums Used In Electric Power Winch

The structure of the winch

The structure of the winch is mainly composed of a drum and a gearbox

Types of winch

The application range of winch is very wide. In order to adapt to different use conditions, the winch can be manufactured into various products of different models. There are many classification methods for models, which are generally classified according to the following methods.

5, According to the transmission form

1) Open gear transmission: the earliest form, currently mainly used for manual winch

2) Closed cylindrical gear drive, mainly for fast single drum winch widely used.

3) taper - cylindrical gear reducer

4) Worm drive reducer

5) Cylindrical gear reducer plus open gear transmission

6) Worm reducer and open gear drive

7) Planetary gear transmission

8) Hydraulic transmission

6, According to the control method

1) hand control hoist, by manual operation of the control hoist hoist or lower heavy objects.

2) Electric hoist, electric control torque control electromagnet brake or make the hoist work.

3) hydraulic control hoist, with pressure oil control hoist drum clutch and braking

4) Air-controlled winch

5) Automatic control winch, with a limit to control the work of the winch.

7, By use.

Due to the different uses of the hoist, the difference in the use conditions, its structural design is also different

1) Lifting heavy objects requires a certain speed and high safety.

2) equipment installation, the quality of general equipment is large, it requires that the hoist has a large lifting capacity, in order to ensure the installation accuracy, the speed can not be too high. In order to prevent falling, its safety requirements are higher.

3) traction items, because this work is generally carried out in the horizontal or inclined direction, in order to make the items can move before and after, the requirements of the winch drum can work.

4) pile driving, requiring the hoist to lift the weight to a certain height, can make the weight into a free fall to achieve pile driving, that is, the hoist with slip performance.

Although hoist can be divided into many types, in fact, due to the application of complex, difficult to definitely distinguish them, and often, a hoist a few work to do, so on the design of the hoist to use a share is not very clear, but high as required to design, so that can make the hoist realize multi-usage, get more extensive application.
