Lifting magnets use electromagnetic power to hold heavy materials firmly without requiring the need of other holding equipment. They are extremely useful in situations where another method of lifting material would not be possible.
Magnetic lifters are used for wide range of applications. They are efficient, lightweight and cost-effective way of transporting heavy materials in particular situations where it would be difficult or expensive for other method of material handling.
Lifting magnets use electromagnetic power to hold heavy materials firmly without requiring the need of other holding equipment. They are extremely useful in situations where another method of lifting material would not be possible.
The magnets vary in size. Usually, magnets that come in larger size are allowed to hang from a chain on a crane that can easily move it into the direction on which the material has to be retrieved. This most efficient lifter can be used for multiple purposes, including construction, automobile junking, cleanup and many more.
How it Works
Lifting magnets can be of two types- permanent magnets and electromagnets. Permanent magnet utilizes specialized material or permanently magnetized material to create the power. They can efficiently lift load up to 2,200 pounds. Also, they can be moved easily from one location to another without any hitch. However, one major drawback of this type is that they have limited lifting capacity. If a heavier capacity lifting machine is required, the best choice is the electromagnetic lifter.
The latter utilizes a powerful electrical coil wound around steel core to adjust magnetic forces within ferrous materials in a similar direction, thus creating an efficient magnetic field. It also requires a constant DC power source for operation. Therefore, an emergency power supply is integrated for this type of lifting solution.
Permanent magnets are useful-
On the other hand, electromagnets are suitable in situations where varying strength or remote magnet control is required.
Common Applications
Permanent lifting magnets are manually operated material lifting solution. They are strong but create a very low magnetic field. Therefore, they are susceptible to the air gaps between the load and the magnet. When the gap increases, the force cerate by the magnet will be reduced. They work best on smooth and flat surfaces rather than rough ones.
The thickness of material to be lifted also considered while selecting a lifting magnet. Thick materials are the best and those thinner materials than the actual specification the lifting magnets will have lower holding force.
Advantages of using Lifting Magnets
The use of this powerful material lifting solution can save time by reducing or eliminating blocking. They are also efficient as they eliminate or reduce waste. They reduce the chances of product damage that are commonly caused by chains, hooks, and other mechanical grabs. But the most important or significant advantages of lifting magnets are its user-friendly nature, ease of operation and cost-effectiveness.
