Industrial hoists are perfect for providing vertical lift and they are very simple and easy to operate. But, as with buying any new equipment for your workplace, it’s important to consider the purchase carefully.
In this article, we will identify some important factors that you should take into consideration before investing in industrial hoists for your business.
What are hoists and how do they work?
Hoists are used in a wide variety of workplaces including factories, workshops, garages and warehouses to aid with the lifting and handling of very large and heavy objects.
Mechanical hoist equipment works by distributing weight using pulleys or gears to transfer low force over long distances into larger forces applied over shorter distances. They can be used in both fixed and mobile applications for general purpose lifting or for specialised purposes, such as removing a part from a car.
What factors do I need to consider before purchasing an industrial hoist?
The weight of the load
This is one of the most important factors to consider when purchasing a hoist. As a general rule of thumb, for less than ten tonnes of lifting capacity, a chain hoist is preferable. However, for lifting greater weights, an electrical wire hoist is most suitable.
The lifting speed
Hoist lifting speeds vary widely and need to be considered carefully before making a selection. Generally speaking, faster lifting speeds are preferred for long lifts or for shorter lift applications where a lot of lifting needs to be completed in a short period of time.
The height of the lift
This is also an important factor. Usually, chain hoists have a container in which the excess chain is stored. Naturally, the greater the height, the longer the chain, and this means a larger chain container. You will need to consider how big the chain container will be and whether or not you have space on your premises for it.
The power source
For low duty use, a single-phase hoist is enough. If, however, you need extremely high duty cycles, then it’s best to go for a three-phase hoist. This way you can ensure that you have enough power for the machine’s operation.
Safety features
As with any new purchase for your industrial environment, safety is a really important factor. The safety and wellbeing of your workers needs to be your number one priority and so look for a hoist that has all the essential safety features such as load limiters, self-adjusting brakes and thermal overload protection.
What are the different types of hoists?
Manual hoists
For when a power source is not nearby or the hoist only needs to be used on an occasional basis, then a manual one is the best choice. They are compact, lightweight and generally have a lifting capacity of around 6 tonnes as well as a lifting height of a maximum of 6 metres.
Manual hoists can also be equipped with ropes instead of chains, depending on the load that needs to be carried.
Electric hoists
An electric hoist is an obvious choice when this piece of equipment needs to be used regularly and also requires precision. Many models are fitted with a lifting speed adjustment system that features at least two operating speeds, as well as an emergency brake.
Pneumatic hoists
These hoists are quiet, sturdy and precise, making them an ideal choice for many industrial applications. They require a constant supply of compressed air to work but have a much faster lifting speed than other types.
Pneumatic hoists are dust- and moisture-resistant, but require regular cleaning of the air filters to keep them working well.
