Hoists are industrial equipments used for the process of lifting or lowering heavy weight objects with the support of a drum or a wheel around it. These hoists are popularly seen in construction or industrial sites where heavy weight objects need to be lifted and moved from one place to the other. Hoists play a very important role in various heavy weight industries by mostly using an electric chain or a wire rope to lift objects.
Earlier, hoists would be operated by hand with the help of blocks and tackle, or even with the help of pulley systems. These days, electric hoists are very popular. These hoists are generally used to lift and lower objects vertically. However they can also be mounted on a crossbeam that allows them to move in a horizontal direction thereby expanding their merit to a great extent. Electric hoists can also be controlled with the help of a remote switch, thereby improving the safety and capacity of this device.
The development of the engine improved and boosted the power of the hoists manifold. The engine gave a motor to the hoist, thus intensifying the power of the hoist. The harnessing of electricity for domestic and industrial use gave hoists unprecedented power. Currently, hoists are capable of lifting very heavy loads. Smaller hoists are intentionally designed for lifting lighter loads up to a few hundred kilograms, but industrial capacity hoists can lift up loads up to several hundred tons.
There are chiefly two types of electric hoists namely electric chain hoists and wire rope hoists available on the market. The former uses chains to lift up loads whereas the latter utilizes wire ropes to lift up loads. Both types of hoists are preferable for lifting up loads, however in some circumstances the wire rope hoist is preferred.
Choose a hoist that will last long. Also ensure that it will provide reliable and robust service. It’s a good idea to check if the hoist meets the statutory and industrial regulations for lifting heavy loads and meets other necessary safety parameters. If you are finding it difficult to purchase a hoist, then you can look up industrial catalogs and hardware stores. At the same time, a number of reputed manufacturers sell directly over the Internet. With some experience, you will surely be able to pick up the right type of hoist for your requirements.
