While hoists are primarily used for lifting and lowering loads in the vertical direction, winches are suitable for vertical movement as well as horizontal and even, to a limited extent, inclined towing. Let's see what you need to know about these machines!
What exactly is a winch?
The winch is one of the simple machines Lifting a mechanical device operating on the principle of a from a cylindrical rope drum mounted on a stand, the reeled up wire rope, or rotating the drum by means of gear ratios consists of folding.
The drive can be solved by human power, it is manually driven winch, as well as by using machines, electric or internal combustion, hydraulic, and even pneumatic motors. Remote control is now a standard solution for the larger winches.
The winches secure operation of, i.e. to prevent the rope and the load hanging at the end from returning mechanical handle or brake.
With the right drive and gear ratios and high tensile strength wire ropes, very heavy-duty winches can be created.
Areas of use of winches
The winches in countless places are used: they are fitted to various industrial machines - cranes of all sizes and capacities, bucket dredgers - but winches can also be used to raise or lower sails on sailing boats and to move the anchors of small and large ships.
Winches can also be found as lowering and raising mechanisms for doors or gates, and in gliding.
The winches are also very useful when lifting loads in places that are not or only very difficult to reach with cranes or other lifting devices.
It should not be neglected!
For winches to work, it is essential that they are in good technical condition, as with all hoists. The wear and tear of winches must be checked regularly, a necessary maintenance, mandatory and ad hoc repairs must be carried out in all cases or should be carried out by a specialist, so that these useful structures can facilitate the safe movement of loads of various sizes for a long time.
