This section provides an overview for winches as well as their applications and principles. Also, please take a look at the list of 6 winch manufacturers and their company rankings.

A winch is a jig, or device used to hoist an object.
The weight of heavy objects that can be transported by human power is defined by standards. Specifically, women over the age of 18, and men between the ages of 16 and 18, are allowed to carry 30 kg intermittently. However, it is not uncommon for industrial equipment to weigh more than 100 kg, and windlasses are used to transport such equipment.
In addition, since a large tensile load is generated during use, there is a risk of personal injury if the hoist is mishandled. The user must be well prepared and have the correct knowledge of the equipment.
Winches are device used to transport heavy loads.
Examples include the transportation of goods at construction and construction sites. Winches are used to unload heavy objects onto a truck or to install them at a construction site.
Since the winch itself only has a hoisting function, it can only transport goods in two directions (up and down), but depending on the usage. Winches may also be used for lateral pulling. A roller is placed under a heavy object, and the winches are pulled laterally to pull the object horizontally. Two winches can also be used for lifting in a narrow space or on a stairway.
There are two main types of winches: electric and manual.
Manual winches perform the hoisting operation mainly by hand. The winch itself consists of a wire, a reduction gear, and a handle. The wire is the part that actually applies the load during hoisting. The wire is wound around the drum to transport the goods. The wire needs to be hard and tough, so steel wire is mainly used. A reduction gear is a complex intermeshing structure of gears. The higher the gear reduction ratio, the heavier the object can be transported. The handle is the part that transmits human power to the reducer. The handle is equipped with a clutch to prevent the wire from moving due to inertia when the hand is released.
An electric winches uses the power of a motor to operate the winches. The motor is installed in the handle section, and the controller enables the winding operation. A separate drive unit is required to transmit the controller's operation commands to the motor. In most cases, electric winches sold as a set with a drive unit.
