Why everyone is choosing magnetic lifters

For a long time, industries where things had to be lifted and hoisted were accustomed to chains and slings and that is about everything they depended on: enter magnetic technologies and people are now shifting their options to this new form of technology. Unlike the chains and clings, magnetic lifters are seriously versatile in their capacity to handle any metals as long as they are ferrous, whether they come in small bundles of scrap or rods or the heaviest weights you can ever imagine. In places where they have been used as a replacement of chains and slings, magnetic lifters have greatly improved the overall performance and productivity such that you only need a single person to lift any weight that may have required more people using the older ways.

There are a number of advantages that magnetic lifting equipment has whether you are looking at labor or quality, the entrance of magnetic equipment has eliminated the need for tapping and drilling of holes in different parts so that they eye bolts could be attached for them to get moved. You will remember that in many cases, those holes had to be filled and some surface refinishing done and this would add to the cost of the product eventually. Magnetic equipment has also eliminated the need for slinging and blocking. Magnets also reduce wastage because they will not mar any metals they are handling; they have greatly reduced the potential of any product damage such as normally happens when you are using hooks, chain and other mechanical grabs.

There are basically two types of lifting magnets available in the market: permanent and electromagnets. Permanent magnets are just what the name says; they are permanent, they have been magnetized permanently so as to create a permanent magnetic field. When permanent magnets are used at a work site, they are normally switched on and off using a lever. In most cases they are used for the handling of flat materials or round parts that generally weigh up to 5,000 pounds. These types of magnetic lifters are self-contained and they can be transferred to different work sites within the machine shop; their only downside is that they have a restricted lifting ability.

Electromagnets on the other hand use electric power to charge the magnets so the material can be held on the magnet’s face. Electromagnets utilize a coil that is energized and wrapped around a steel core so it can orient any ferrous materials to a common direction, thereby creating a magnetic field.

Electromagnets are basically built so they can run on DC current thus creating a need for a rectifier. Unlike their permanent counterparts, electromagnets require a constant source of power but they are the most cost effective magnets per pound lifted with capacities going up to 10,500 pounds.
