JMM Friction Electric Winch is mainly used for long-distance pulling. JMM electric winch characteristic is stable wire rope speed and lifting. Applicable to all kinds of bridges, ports, terminals and another construction projects in large factories, power engineering equipment installation.

Introduction to products:

A friction winch is a mechanical equipment that drives the winch drum to rotate by power and transfers force by steel wire rope to lift objects. The Jmm Friction Type Winch is driven by friction, which will cause wear in the transmission process and needs to be equipped with friction plates or friction sleeves to offset the consumption of friction. JMM friction winch is suitable for lifting, lowering and transportation of items, and the ambient temperature used is generally not more than 40 ° C.

When the friction winch works, the wire rope only passes through and is not wound to the drum, and the working principle is the same as the movement of the belt and pulley, relying on the friction of the drum and the wire rope to pull the object. Such as grinding, elevator traction machines, etc., need to ensure that the wire rope has a certain Angle and pressure on the rope wheel to ensure the necessary friction, if necessary, the pressure wheel can be increased to increase the wire rope on the rope wheel Angle and pressure.

In addition, the machine is also equipped with a ratchet stop device, which can make the drum stay in any required position. The advantage of friction winch is that the motor starts in a no-load state and the starting torque is small. At the same time, the motor does not need to reverse frequently, so that the power grid load can be uniform. In addition, due to the use of a friction clutch, can prevent transmission damage during overload.

1. The working temperature of the friction winch is affected by the heat caused by the friction of the brake and the friction sheet, which will have a certain loss, and there is a problem that the decline speed is difficult to control.

2. Friction winch shall not be used on the construction site.

Application of Friction Electric Winch:

JMM electric rope winch is mainly used for a variety of large, extra-large concrete, special grade concrete, steel structure And steel cable, steel cable long distance traction machine large stroke lifting. It is characterized by the constant speed of wire rope and smooth lifting. Suitable for all kinds of Bridges, ports, mines, wharves, and other road and bridge engineering construction and large factories and mines, power engineering equipment installation.

For example, in some occasions requiring a high-speed operation, friction rope winch can play its high-efficiency characteristics to improve the working efficiency and production efficiency of the equipment; In some cases with large vertical heights, the volume problem of the equipment can be solved by increasing the number of pulley sets and increasing the number of ropes or chains, so as to make it more flexible and convenient; In some cases where the nature of the material is more strict, the transmission efficiency of the equipment and the safety of the material can be improved by controlling the friction coefficient.

Product component:

A friction electric rope winch is mainly composed of a motor, gearbox, brake, friction plate, and rotating shaft. It drives the rotation of the gearbox through the rotation of the motor, and then controls the contact area of the friction plate through the brake, so as to achieve the lifting and tensioning function of the rope.

1. Lightweight aluminum alloy shell; Aluminum profiles produced by extrusion, metal stamping, and surface treatment. It has the characteristics of high flexibility, its practicality is not compared with other types of shells, and it also has the characteristics of waterproof and corrosion resistance, which is very suitable for use in outdoor and larger environments.

2. Electromagnetic brake; It can be freely combined, cut off, or brake according to the need, easy to achieve remote control, and other advantages.

3. Electromagnetic contactor; It can not only switch on and off the circuit but also has low voltage release protection.

4. A 24V/36V transformer device can be customized to adjust the voltage according to customer requirements.

Friction Winch Maintenance:

The appropriate location is selected to make the machine stable and fixed to ensure that it does not swing back and forth when in use.

Before lifting, the first line empty, listen to the machine's internal noise, after everything is normal, then start to work.

If emergency braking is required during the work period, just press the brake handle to prevent damage to the machine parts caused by the double-handle brake, and the flow of mechanical lubricating oil into the brake is strictly prohibited, resulting in brake failure.

Long-term use should pay attention to the brake belt, cannot brake.

Common Failure And Solutions Of Friction Winches

● The drum gear sleeve is overheated.

The main reason for this failure may be the unqualified lubricant quality.

Solution: clean the drum gear sleeve, and then replace it with a new qualified lubricant.

● The big gear bearing of the drum is seized.

The main cause of this failure may be excessive bushing wear.

Solution: replace the bushing.

● The spindle is bent or cracked.

The main reason for the failure may be the overloaded use of the winch.

Solution: repair or replace with a new spindle; strictly control the load of the winch at the rated load and below during the operation.

● Gears are running noisy

The main reason for this failure may have the following two aspects: Incorrect gear installation or Different degrees of bearing wear

Solution: reinstall the gear correctly; replace it with new bearings.

● The gear tooth surface is cracked.

The main reason for this failure may be gear damage caused by long-term overload use of the winch or impact load.

Solution: replace with the new gear and ensure that the winch is used strictly according to the specified load.

● The brake can't be braked or can't be disengaged

The main cause of this failure may be a slack or too-tight brake band.

Solution: adjust the gap of the brake belt and repair the asbestos belt.

● The triangle belt is cracked or twisted.

The main reason for this failure may be the long-term wear of the V-belt, or pulley displacement.

Solution: replace with new belt; adjust and tighten the pulley.


1. The driver of the electric rope winch should be trained and certified to work, concentrate on the work, find obstacles in the line of sight, remove in time, and do not operate when the signal is unclear.

2. Idling should be performed before operation, and the electrical, braking and environmental conditions should be confirmed before operation. The operator should understand the main content and workload of the work on duty in detail.

3. The driver shall not leave the post when the suspended object is not completely on the ground. When resting or suspending work, the object or cage must be lowered to the floor. After work, the power supply should be cut off and the switch box should be closed.

4. The driver should always pay attention to the operating conditions and the wear of the wire rope. When the load changes for the first time, it should first stop 0.5m from the ground and then continue to rise when there is no problem.

5. Using a single barrel winch, you must use the brake to control the falling speed, not too fast and suddenly braking, to slowly fall.

6. Do not use the lever switch to prevent collision and misoperation.

7. The wire rope should be regularly buttered and placed in a special trough to prevent rolling and damaging the strength of the wire rope.

8. When the rated tension of the winch is greater than 125KN, the rope should be set up, the wire rope on the drum should retain at least 3 to 5 rings, and the end of the wire rope should be fixed and reliable.

9. The distance from the outside of the drum to the outermost wire rope should not be less than 1.5 times the diameter of the wire rope.

10. During the operation, no one shall cross the winding wire rope that is being operated.
