Most companies in the manufacturing sector and other industries rely on lifting magnets for the smooth running of their daily operations. This industrial lifting technology allows workers in manufacturing plants to easily lift and move heavy objects. For some, this might sound like an unnecessary expense, but as you will soon find out, it is a smart investment.
A Brief Overview
Lifting magnets are precisely what the name implies. It’s a high-powered magnetic device used to lift objects in factories. It’s also referred to as a portative electromagnetic lift and comes in handy when industrial workers need to move heavy objects. To lift the object, the worker moved the industrial lifting magnet over it and activates the magnet. When activated, the magnet attracts the magnetic metallic object, and the worker can then move it to any location he desires.
There are obviously other ways to lift objects in industries, such as using clampers. The disadvantage with clamping devices is that the object to be lifted must feature some connection point. With industrial lifting magnets, any object, regardless of the shape and whether it has a connection point or not, can be lifted and moved with ease. The only requirement is that the object must either be or contained in a magnetic metallic material.
How Industrial Lifting Magnets Work
Each lifting magnet equipment is designed for use in a specific industrial setting. These electrically activated magnetic devices are extremely powerful and capable of lifting multiple tons at a go with ease. Each lift comprises a metal core enfolded in an electric coil. When activated, the coil is charged with heavy bursts of electricity, which then generates a magnetic field. The coil is often made of copper, but any highly conductive metal could work as effectively. The electrical resistance generated in the coil during operation results in overheating, and insulation is therefore necessary.
The attractive field created around the coil causes the atoms in the metal core to realign themselves. Before activation, these atoms are randomly aligned in what is called the random domains. The electrical current unifies the alignment within the domains in the metal core, amplifying the strength of the attractive field even further.
The device’s working power is attributed to the tightness of the electric coil and the material of the metal core. Scaling these two characteristics is what gives the lifting magnets their remarkable grabbing ability.
When the electrical power is multiplied, the equipment’s attractive force multiplies as well. However, once all the atoms within the core are uniformly aligned, further increase of the electrical power will not increase the strength of the magnet. Most of these industrial lifting magnets are designed in such a manner that it’s impossible to power them beyond saturation.
The major advantage of this technology is that you can turn the magnet on and off as you please. There are also minimum chances of accidents happening because the power can be controlled. The technician can easily decrease or increase the electrical power input with button controls making separation and transport easier and safer. This is particularly helpful in iron recycling plants where pulling and separating iron and steel is necessary.
Most industrial lifting magnets have backup systems for safety precautions. The only disadvantage is that these devices rely on electricity to function. When electricity is suddenly cut, it could cause major safety hazards. This is what makes the permanent magnet backup system an important part of industrial lifting magnets.
A permanent magnet will not require electricity to maintain the grip. These backup systems are made of metal alloys that have been magnetized with strong electrical fields. When the electricity supply is suddenly cut off, the metal alloy will maintain its magnetism and hence no safety hazards. With an industrial lifting magnet, you have all the lifting power needed to move literally any metallic object in your factory.
Benefits of Using Lifting Magnets
There are numerous benefits associated with using lifting magnets in industrial settings (also see: https://magnetized.com/), among them being lower cases of musculoskeletal disorders (MSDs). Millions of industrial workers report MSDs such as pulled muscles and back pains caused by improperly lifting heavy objects. When a worker is forced to lift awkwardly shaped objects or heavy objects, he/she may end up suffering an MSD injury.
According to OSHA, about 33 percent of all workplace-related injuries are MDS related. Industrial workers can avoid MSDs by using industrial lifting magnets as opposed to lifting heavy objects manually. The magnets will perform the work for you, eliminating the need to lift the objects physically.
These devices also enhance productivity in the industrial process. Besides being laborious for industrial workers to manually lift heavy objects, it is also very time-consuming. A slow-moving manufacturing process will hurt a company’s profits. Automating the lifting and moving of heavy objects with a lifting magnet increases productivity. Industrial lifting magnets make it possible for factory workers to move heavy objects with ease. They will also increase productivity and reduce the risks of injuries among workers.
