Classification of hoists based on their types

Classification of hoists based on their types

Depending on the load that is going to be lifted, unloaded, or moved, hoists can be divided by two main characteristics, to understand it more easily:

1. The source of energy used to perform the loading and unloading, be it manual, electrical, pneumatic, or hydraulic.

2. Lifting means used to support the load, cable, or chain.

In the market, there are multiple configurations for hoists depending on the lifting means used, the assembly of the system, energy sources, and load capacity. It may seem challenging to understand and take into account all these variables, but to help you know which would be the most recommended for your need according to the following parameters:

The first thing, do you know what a hoist is?It is a machine composed of a combined pulley system where fixed pulleys and mobile pulleys pass on the same rope. These systems allow lifting large loads since, with each pulley that is coupled, there is a decrease in the force needed to lift the load. Bear in mind that the greater the number of pulleys, the lower the power or strength applied to move loads with large weights and volumes.

What is its primary function?Day by day, it is more common in vertical work to move loads whose masses are too heavy to move by applying the force of one or more people. To solve this need, hoists are usually used. Having said this, we conclude that the primary function of a hoist is lifting and moving objects that are too heavy, where it is not possible to use the force of a person. They can be differentiated according to their size or lifting powers. The small ones are manipulated manually, like the chain ones, and the larger ones work with electric motors to make them work.

What is its usefulness?These machines are beneficial in sectors of industry, construction, workshops, among other sectors where it is required to lift and place cumbersome elements and materials in different places. Thanks to their pulley systems and the lifting system used, whether manual or electric, they are frequently used for their simple functionality, safety, speed, and efficiency.

Do you know the difference between chain hoists and wire rope hoists?As we have been mentioning, hoists are the most widely used lifting machines in different economic sectors and with many applications. Below we describe the differences between the types of hoists and the aspects that you must consider when making your choice:

Chain HoistsThey use a steel chain linked together, with a similar function to ropes, and it has a hook where the load is hooked. They can withstand types of cargo up to 5 tons. They can withstand more aggressive work environments such as corrosion, gases, or dust. In need of an Electric hoist supplier? There are many in the UK that can deliver your needs.Cable HoistsWire rope hoists are typically galvanized steel or stainless steel strands interwoven for greater strength. They can withstand types of cargo up to 30 tons. They support milder environments.
