Electric Winches

An electric winch is a device for lifting or pulling loads in construction, industry, and vehicle-mounted installations. Thanks to its high power and simple controls, the mechanism is used in industry, warehousing, and other fields.

Design

An electric winch consists of the following components:

1. Electric power unit. Provides torque and drive. It determines the power of the electric winch.
2. Drum. Used for winding the cable. Connected to the reduction drive.
3. Frame. The main structure of the mechanism, which is fixed to a wall, floor, or vehicle.
4. Stopping system. Needed to lock the cable in the required direction.
5. Cable or belt. Differs in strength, diameter, and material, which determines the load-lifting capability. Directly affects safety.
6. Controls. Most winches are equipped with lever or button controls.
7. Reduction gearbox. Needed to reduce the rotation speed of the electric motor relative to the drum.

Classification

Electric winches are classified according to the following criteria:

1. Fixation method. Divided into stationary and portable models. Operation requires connection to an alternating current source of 220 V or 380 V. Mobile models are used for lifting loads of up to 300 kg. Stationary models can move loads over 5 tonnes.
2. Area of use. Both automotive and standard units are manufactured. In the first case, the drive runs on a battery. The device is additionally connected to the vehicle’s electrical system.

Scope of application

A construction electric winch is a versatile device used in the following areas:

1. Lifting goods or materials to the required height. For this, JM electric winches are used, which feature increased load capacity and cable length, allowing loads to be lifted above the 10th floor.
2. Performing various operations during installation work.
3. Freeing a vehicle from locations where transportation is particularly difficult.

A pull-type electric winch with a remote control can be used to equip mast devices, cranes, and a range of other machinery.

How to choose

Manufacturers state maximum load capacity under ideal conditions, without accounting for friction or lifting factors. Therefore, it is necessary to consider the safety margin, the ability to replace the cable, ease of repair, and the reliability of the electric motor. The strength of the frame metal, weight, and warranty are also important.
