Friction Winch

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.

Applications of AQ-JMM Series Electric Friction Winch

Electrically driven friction winch provides constant line speed and stable operation. It is commonly used in road and bridge construction projects, large factories to lift and pull heavy load efficiently and safely. The line speed ranges from 5m/min to 20m/min.

Another common application is to pull large ships ashore or for ship breaking.

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.

Advantages of Using Friction Winches

The electric friction winch has a large pulling force, from 10 tons to more than 80 tons. It has two major advantages:

  • The rope outlet position of the winch remains unchanged, so there will be no deflection angle of the wire rope, which reduces the wear of the wire rope and increases its service life.
  • The pulling force and speed of the rope are constant, so the whole winch machine runs stably and the impact force is small.

The Main Structure of The Friction Winch

The friction winch uses the friction between the wire rope and the drum to generate tension. The main structure includes two friction drums, a rope storage drum and a rope pressing device.

Friction Drum

The friction drum set is equipped equipped with rope grooves to increase the friction between the steel wire rope and the drum. The number of rope grooves is generally 6-10. In addition, it is equipped with a power mechanism.

Rope Storage Drum

The rope storage drum is only used to store steel wire ropes and does not provide pulling force. It is controlled by the drive torque of the frequency conversion motor, which can better maintain synchronization with the friction drum.

Since the rope storage drum is not too far away from the friction drum, a rope spooling device is generally provided.

Rope Pressing Device

The function of the rope pressing device is to prevent the wire rope from falling out of the groove after being loosened in a non-working state. The rope pressing wheel is generally synchronized with the drum set through the sprocket chain drive, and the rope pressing device is a mechanical type.

Factors to Consider When Choosing A Friction Winch

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.

Power source

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 drum 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.

FAQs

How Does A Friction Brake Winch Work?

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.

What Are the Control Modes of Winches?

We provide local control by default, and the control button is outside the electrical box. According to different customer needs, we can also provide remote control, console operation, etc.

How Do You Provide After-sales Service?

We provide 7*24 online services, and our engineers remotely guide customers to solve problems. But if the problem cannot be solved, we can send an engineer to the site.

Can You Provide Free Installation Services?

We can send 1 or 2 engineers to the site to guide the installation, but you need to pay salary, round-trip air tickets, visas and accommodation.

Is The Winch Easy To Install?

All of our winches have been well assembled and finished commissioning before shipment. Customers only need to make the foundation according to the drawings we provide. And after the equipment arrives on site, simply connect the winch to the local power supply.
