Product Specification

Non - Standard Aolly Steel lebus grooved Drums Hydraulic pulling winch

LBSW Hydraulic winch primarily consists of four parts, including oil distributor, hydraulic motor,brake,drum and stand. The oil distributor inciuled one-way balance valve, brake and high pressure shuttle valve.

Use of winch

The main uses of the winch are as follows: first, as lifting equipment, it is used for mine lifting, sinking lifting and suspension (lifting) sinking equipment and facilities, that is, along the shaft lifting ore, waste (gangue) stone, lifting personnel, lowering materials, tools and equipment; Second, it is used as transportation equipment for underground scheduling and transportation of ore (harvester), stope rake ore (slag) or filling, removing columns, etc.

Characteristics of 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, still can design according to need directly integrated in the motor oil distribution valve group, 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.

Adjustment of winch 

After the winch is installed, it must be inspected and adjusted.

1, open gear transmission, tooth side clearance is 0.42mm, the contact area along the tooth height is not less than 40%, extension tooth length is not less than 50%.

2. Check whether the driving system of the working brake is flexible and reliable, and adjust the gap between brake shoe and brake wheel not more than 0.7-0.8mm when releasing the brake.

3. Check whether the transmission system of the safety brake is flexible and reliable, and adjust the gap between brake shoe and brake wheel is not more than 1.5mm when the brake is released.

4. Check whether the control appliances of the working brake and safety brake are interlocked with the main motor, that is, start the working brake of the main motor and stop the main motor, the working brake will brake, and only the safety brake can start the main motor.

Product Outline Drawing:

​

Our company early introduction of advanced technology at home and abroad, after years of research and development and improvement, in the hoisting machinery multi-layer wire rope row rope field has made a major breakthrough,

In 2010, the company obtained the production patent of double folding rope groove drum, and founded its own brand - LBS. At present, the company has formed a mature and stable, serializedproduct production mode.

When the split type drum fence skin is installed, the split fence skin sleeve is wrapped on the smooth slotless drum, and is closely connected with the drum through bolts or welding, so that the original smooth surface of the drum outside the surface becomes the form of lebus double folding rope groove, which is convenient for the application of winch modification or replacement of the drum.

Our factory has more than 2000 sets of advanced equipment such as casting, forging, gear processing, sheet metal stamping, riveting, heat treatment and mechanical processing. In recent years, the

Germany CW1000 machining center, CNC four axis, five axis linkage machining center, CNC punch, large CNC hobbing gear grinding machine, large CNC floor boring and milling machine,

Vacuum electron beam welding, CNC welding robot and 80 roll machine and other advanced processing equipment.
