Working with Electric Chain Hoists

Whenever you face a job that involves heavy lifting, having the right material handling tools on hand can save you time, money and unnecessary stress. In such situations, an electric hoist proves incredibly useful. These machines are capable of easily and quickly lifting heavy items, allowing you to move them from one location to another, comfortably and safely.

There are three different types of electric hoists available on the market, including hydraulic hoists, manual hoists and electric hoists. While each has their pros and cons, the electric variant is designed for industrial and small scale applications.

Electric hoists are normally sold in single, dual and three phase power levels, which should match the power supplied by your plant. Wherever possible you should pick a three phase hoist as there is much less current drawn than single phase, allowing the motor to run cooler and last longer. Single phase is available for electric hoists, but capacity is limited. Constant speed hoists, as well as dual-speed hoists, are also available. Some of the benefits of electrical versus manual hoists are that they offer fingertip control and can lift heavier loads.

An electric chain hoist has a capacity range from 1/8 tonne to 5 tonne. This is the standard weight load, but there are chains out there that can handle more. If you are working with a chain the carries up to 5 tonnes it is great for light and medium lifting (according to the Hoist Manufacturing Institute, these chains are perfect for H4 & H3 services). These machines are compact, light, and require low investments costs. You should be careful. Working with a manual or trolley crane over 15 feet high can cause a slingshot effect when lifting, and this can make working difficult.

Electric type hoists could serve you for many years if well-maintained. A consistent inspection schedule will help to keep your machine in proper shape, particularly when used often. Both hydraulic and manual chain hoists are susceptible to high rates of wear. Manual hoists are hugely mechanised in their functioning and structure. Hydraulic hoists are susceptible air leaks due to broken seals that call for frequent maintenance work. Both hydraulic and manual chain hoists include a higher number of moving parts within their assembly like swivels, pivots and gears. This requires more frequent servicing to keep the whole unit in excellent working condition. Repairs could be very intensive on these hoists which add to overall costs.

Using them is inexpensive as compared to cranes. They also prove to be a cheaper option as compared to hiring workers for this task. Very little labour is required when you are working with electric hoists. This is due to their efficiency and high carrying capacity.

There are some disadvantages of electric chains such as that they can’t be used in high places, but the advantages far outweigh them. People working with them should be very careful and have proper know how about the operation of the hoist otherwise they may hurt the operator. Partial knowledge is dangerous so it is better to be aware of the proper guidelines of their working. Just using Electric Chain Hoists once will let you forget manual hoists for a lifetime!
