Where did winch? Who invented it? In our time, resurrect the series of facts and find answers to these questions are really hard. Since ancient times, winch used to lift various loads. The basis of the winch is rotating block. One of the first winches were only a mechanism similar to the pulley. Burton – this is the relationship of mobile and fixed units are bent by a plastic element (rope, chain or rope).

None less modern winch is a relatively tricky mechanism. The device uses a special winch parts warn spontaneous lowering of loads. It is used for vertical uplift on yachts, as well as by She lowered elevator car in a high-rise building. Applies as well for towing of non-motorized boats and fishing boats on the winches out nets with fish. The winch is a device that pull force is given by rope, chains from the drive drum. In addition to lifting heavy loads every winch is widely used, and when you move a large object, based on automotive winches is the principle, and rightly appear automobile hoists a wonderful tool to rescue bogged down in mud car. There are lots of kinds of winches, each for a special occasion, in an environment where we can restrict their own physical force is used manually, and if his forces could not handle the rescue comes an electric or hydraulic winch. Constituting part of an ordinary electric winch with a motor, drum, frame and braking system.

The mechanism of automotive winch is mounted on the car, he intended to move it by twisting the cable, while the free end of which is attached to the immovable object – firmly established and far greater weight. The hydraulic winch is powered by hydraulic motor, usually actuated steering pumps. Hydraulic car hoist has a lot of fundamental advantages such as resistance to overload (overload motor is not broken, but simply stops working), the reliability of the hydraulic motor, and also can not exclude the possibility of working under water, as the motor is hermetically sealed. When choosing winches to take into account such factors as load index winches, the heavier the car, the higher should be indexed. Load index indicates the limit pressure, which can produce a winch when thrust load horizontally (to pull the vehicle over the asphalt enough effort at 100 pounds). Winch, having a high index of carrying capacity, are expensive, but they are reliable, wear under different conditions operation.
