Friction winch is designed with two friction drums along with a wire storage drum behind it. It is ideal for long-distance traction and large-stroke lifting of various large to extra large concrete structures, steel structures and steel cables. The winch has large load capacity, simple operation and reliable performance.
|Load capacity||0.5~100 t|
|Rope capacity||20~5000 m|
|Working speed||5~20 m/min|
|Power supply||220-690V, 50/60HZ, 3Phase|
AQ-JMM Series Electric Friction Winch For Sale
Electrically driven friction winch provides constant line speed and stable operation. It is commonly used in road and bridge construction, large factories to lift and pull a heavy load efficiently and safely. The line speed ranges from 5m/min to 20m/min.
This type of winch is a cost-effective option for your lifting and pulling requirements. It requires lower operational cost as compared to a hydraulic winch. Remote control is available as optional for a much safer winching operation.
According to your work situation, we will help you choose the right equipment.

Friction Type Winch Design
Our winches can be designed for a specific load capacity with various options and additional features to make sure you end up with a perfect winch system.
Tailor-made winch products
Winches are tailor made products that can suit each and every lifting or pulling requirement of the customers. We can help you in the entire selection process of the winch and offer you the most appropriate proposal.
Factors to consider in winch design
- W.L.L (working load limit)
The maximum load capacity or pulling force occurs on the first layer of the rope, and it will decrease for each additional rope layer. It is critical to determine the working length of the rope on the drum. 3 safety windings which always remain on the drum should be added to ensure a safe winching operation.
- Motive power
The winch can be designed to be electrically or hydraulically driven. Each type has its own pros and cons. The selection of motive power depends on the available power supply, user’s preference and financial reasons.
- Winch drum
This type of winch consists of two friction drums and a rope storage drum behind it. The drum size is largely determined by the designed winch capacity.
- Line speed
The speed can vary widely which is determined by the purpose of your winch. The equipment can be designed with single speed or two speed motor. Sometimes it may be more useful to equip it with a variable speed by using an electric frequency inverter (for electric winches) or a proportional control valve (for hydraulic winches).
- Braking system
The winch can be designed with motor brake, transmission brake and band brake for a safe operation. Each lifting winch is configured with a fail-safe braking system. For accurate positioning and safe lifting, a motor brake is advised. Band brake is an extra brake fitted on the drum. It can be operated manually or hydraulically depending on your requirements.
- Winch controls
Local control and remote control are available for you to choose from. For electric winch, a pushbutton control box fixed on or near the winch is used to control the drum rotation. Another popular addition is remote control which can be either a control pendant or wireless remote control to keep the operator safe. For hydraulic winch, hydraulic power units (HPU) is required to operate the winch. It is provided as customized.
- Winch options
There are a range of options and accessories available to make the winching operation efficient and safe, such as pressure roller, spindle limit switch, drum guard, rope guide, band brake, clutch, additional rope anchor and manual emergency crank.
Working of Friction Brake Winch
The winch machine consists of two grooved drums that are arranged in line to run the line using friction and a larger drum that is used to reel in the rope for storage. Unlike conventional winch which deforms wire beneath, this type of winch allows the crushing pressure of the running rope under tension is taken by the grooved drums directly.
