·Convenient to use.

·Test certificate for safety factor from third party.

·The Magnetic Lifters are ruggedly built.

·No Maintenance and Operating cost.

·Made with high energy rare earth magnets (NdFeb).

·Mechanical Switching by turning a lever with a locking.

·System against switching off accidently.

·No damage to the work piece being lifted.

·Easily transportable.

Principles:

These are two Pole Permanent Magnetic Lifters. The two poles are at the bottom of the lifter. These lifters use high grade NdFeB Magnets for producing strong magnetic flux path through the two poles. The lifter is placed on the MS flat/block that is to be lifted. The turn of the handle in its ON position with MS flat/block/cylinders (to be lifted) at the bottom ensures completion of magnetic flux path through the MS body. The MS body gets attached to the lifter. The turn of the handle in its OFF position detaches the MS body from the magnetic lifter.

Application:

The magnetic lifters are used for loading/unloading and movement of objects within the factory premises. These can hoist iron sheets / blocks and cylinders. Due to its light weight, small size and high effort/dead weight ratio, these lifters find its use in MS fabrication, machining, steel rolling mills/industries, ship yard, warehouses, docks, press tool and plastic injection molding industries, and factories.

Benefits:

·More effective use of available floor space by eliminating gauging and increasing stacking height.

·Huge & heavy work pieces can be moved and handled safely & easily by a single Operator.

·Labor saving, time saving - improving productivity.

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.

1.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.

2.LOAD LENGTH OR 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.

3.LOAD THICKNESS:

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.

4.LOAD ALLOY:

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.
