The dictionary of the Royal Spanish Academy (RAE) indicates that the etymology of the term winch is uncertain. The publication suggests that the concept is possibly linked to the Occitan word they restrain.
A winch is a turnstile: a simple machine equipped with a cylinder what, thanks to wheels, storks or levers, revolves around your axis and it can act on the resistance by means of a rope that is wound around the cylinder itself. There are different types of winches, intended for various uses.
Usually a winch -also called winch– is used to achieve the heavy weight displacement. You can have a motor that allows the lathe to be operated or driven manually or by a animal.
This means that a motor (hydraulic, electric, or otherwise), a person or a draft beast can provide the energy needed to make the winch cylinder turn. Said cylinder is attached to a rope, a string or a cable, which can be tied to a load so that it can be lifted or moved.
In its operation, the winch helps to move a bundle without having to do much force. It is important that the cable or the element used to tie the load is resistantas otherwise it may break.
Winches have multiple uses. In many industries, for example, they are used to drive belts and production lines.
These machines also serve to deposit materials in hoppers. On the other hand, there are off-road cars and trucks that feature a winch on the bumper or bumper, being useful if the vehicle gets stuck in the ground or cannot avoid an obstacle: in these cases, the winch cable can be hooked to another car or to a tree.
The mining It is a sector where the winch is very popular. This lathe is usually key to the extraction of cages with operators or of materials from inside the mines.
Cages carrying workers can be lifted vertically with a winch. The device can even be used to pull a train wagons and move the formation along an incline.
It is possible to recognize different artifacts and resources that work in a similar way to the winch. One of them is the winch, which has a drum on the top and levers below.
The cranes have a vertical axis that rotates and with pulleys to lift a load. The pulleys, in turn, are mechanisms consisting of a rotating wheel; This wheel has a knurled edge so that a rope can slide through it and thus move a weight.
The winches also refer to the argans, which are crane-like machines. They even share properties with slings, as the ropes that bring hooks.
As can be seen, the human being He has devised various devices for lifting heavy weights using little physical force.
