Magnetic lifting equipment consists of permanent and electrically-activated devices that are mounted to a transport machine. These devices can achieve impressive load forces while maintaining excellent safety and efficiency. They offer many advantages over traditional hydraulics and are cost effective. Most combine the power of an electromagnet and a permanent device into a single system known as a permanent-electro lifter. This ensures the machine is operated safely at all times while also providing excellent load forces. These devices are used in several industries where transporting or separating ferrous materials is needed. The metalworking, recycling and construction industries, in particular, make frequent use of these machines.
The main drawback to permanent magnetic lifting equipment is that, on its own, it can only pick up about 5,000 pounds (2,300 kilograms) of material at one time. This is enough in many situations, but facilities that require more power will need to turn to electromagnets to get the job done. Electrically activated devices are powered by a resistance coil made of conductive materials. As electricity is charged through the coil, it creates an attractive force that can capture large pieces of iron or steel. The tighter the coil is wound, the more power there will be. The strength of the electrical current will also increase the amount of loading power. The metals the device is built out of will also have an impact on the strength of the attractive field. Finally, to achieve maximum power, there should be no gaps of air between the device and the loaded material. Because these factors can all be controlled, magnetic lifting equipment can be easily controlled as well.
However, the problem with electrically-activated devices is that they require a constant electrical current to function. Once the power is cut, the machine loses its ability to hold a load. To overcome this safety risk, most manufacturers combine these devices with permanent magnets, which don’t require power to function.
Traditional loading machines use hydraulics to maneuver materials around. Over time, these machines are worn down by friction and heat. As the machine ages, it will decline in performance until it becomes a major safety hazard. Hydraulic loaders are more expensive to maintain because of this natural wear and tear. Magnetic lifting equipment, in contrast, is very inexpensive to maintain because the loading device contains no moving parts. It maintains performance for much longer and is less likely to become a safety hazard as it ages. These devices are easy to handle and load with greater speed than other machines. They can also be designed to fit into compact spaces, so they offer a compact profile where space is a premium.
Magnetic lifting equipment is extremely useful in any industry that needs to move large loads of steel or iron around. In the recycling industry, powerful permanent-electro loaders are primarily used to separate iron and steel scrap from other materials. Because iron and steel must be processed separately from other material, this is an important step for maintaining product quality.
With the power of permanent-electro loaders, processing plants can operate with greater efficiency and safety.
