A Spreader Beam Electro Permanent Magnetic System is the most efficient and cost- effective way for lifting various sizes of MS sheets, plates etc. A spreader beam EPM system consists of a multiple arrangement of electromagnets placed in a design so as to gain the maximum output of each of the magnets. The design is so good that they in turn form a stable structure that can lift very large dimension sheets with ease. Spreader beam EPM is a very useful resource for industries that have to deal with huge amounts of day to day material handling.
Made completely out of steel. Forged hooks, heavy duty chains, Spreader Beam Electromagnets provide the best sheet lifting solution for lifting and transporting large size sheets from one place to the other within the shop floor. It uses an Electronic Control Board Panel to operate with ease. It can lift, hold and drop sheets with a click of a button!

Important factors for the safe operation of lifting device:
Load characteristics other than just weight must be considered in order to determine the weight that any magnetic lifter can lift. This statement is true for any lifting magnet because they all operate on the same fundamental laws of Physics. Magnetic power is pictured as lines of force flowing from North to South Pole. Anything that limits the flow of these magnetic lines of force obviously reduces the magnet’s lifting ability. There are four important factors which limit the flow of these lines of force.
Load Surface Conditions
Magnetic lines of force do not flow easily through air, they need iron in order to flow freely. Therefore, anything that creates an air gap between a magnet and the load, limits the flow of magnetic force and thus reduces the lifting capacity of a magnet. Paper, dirt, rust, paint and scale act in the same way as air, so also a rough surface finish between the magnet and the load.
Load Length and Width
When the length or width of a load increases, it ceases to lie flat and the load begins to drop at the edges. The drooping/sagging of the load can create an air gap between the load and the magnet. If this occurs then the lifting capacity of the magnet is reduced.
Magnetic lines of force are more effective when they flow through iron instead of air. The thicker the load, the more the lines of magnetic force. After a certain thickness of load, no more lines of force will flow because the magnet has reached its full capacity. Thin material (load) means less iron available and thus fewer lines of magnetic force flow from the magnet into the load. Therefore, the lifting ability of the magnet is reduced. Every magnet is rated for minimum thickness of load to reach full lifting capacity. Below such thickness of load will de rate the lifting capacity of the magnet. In general, it can be said the load must be thicker than the width of one of the magnet poles.
Low carbon steels, such as soft Iron or Mild Steel are nearly as good conductors of magnetic lines of force as pure iron. However, if the alloys contain nonmagnetic materials, they decrease the ability of magnetic lines of force to flow into the load. An alloy such as ANSI304 of Stainless steel is almost as poor conductor of magnetic force as air.
Position of Magnet’s Lifting Surface
As the position of the magnet’s lifting surface changes from horizontal to vertical, the lifting capacity of the magnet decreases. When the magnet’s lifting surfaces are vertical, the lifting capacity of the magnet is minimum and dependent upon the coefficient of friction between the magnets lifting surface and the load.
