The electrically switchable telescopic arms of the Battery Telescopic Magnetic Beam EPMBL-T have a range up to1000 mm per side. This makes them extremely flexible in their use for lifting and transporting processes.
The integrated rechargeable battery box means that no power connection is required.
Sheets from 4 mm thickness of different sheet formats (up to 12 t) can be transported and lifted gently, safely and quickly.
The remote control can be used to operate the tapping function (inching). Sheets with a thickness of 4 mm or more lying in the stack can thus be separated.
With 400 switching cycles, the battery shows high efficiency in its performance.
The Electropermanent Magnet Modules (EPM) are made of solid steel. Electropermanent magnets combine both electric and permanent magnet technology. It is a permanent magnet that is switched on and off electrically. When the battery level is low, the load remains on the magnet module without any loss of magnetic force.
When switching ON/OFF the permanent magnet system inside will be moved against the pole surface. When the magnet is OFF the magnetic flux will be shortcircuited by the pole surface (Graphic 1). When switching ON the magnet, the magnetic flux will flow through the pole surface and the workpiece on top will be attracted and close the magnetic flux circle (Graphic 2).
Features:
With the help of a permanent load lifting magnet one can lift, move, place and transport ferromagnetic objects, as well as round or flat material. The pieces can be flat or cylindrical. The transport of round parts can also be carried out by means of a V-shaped recess on the holding surface. The lifting forces always depend on the material thickness.
The extraordinary adhesion of these devices, which are often referred to as solenoids, results from the use of NdFeB magnets (neodymium-iron-boron is an alloy of neodymium, iron and boron with the composition Nd2Fe14B from which the currently strongest permanent magnets are produced).
Advantages of a lifting magnet
The area of application of permanent load lifting magnets is very versatile. Everywhere where loads are to be held or handled without gripping, these lifting magnets are used. With these load holding devices, you can work quickly and safely. Their low external dimensions, simple construction, low weight and large performance spectrum guarantee an uncomplicated application.
It is a great help with loading/unloading operations (during all handling operations). These lift magnets are the ideal lifting devices in warehouses, workshops, tool factories, shipyards, steel construction, foundries, steel construction works, movement of injection and punching tools, etc. They offer handling solutions of all kinds, serving from small workshops to large industrial/manufacturing companies workshops. These operating magnets result in zero operating costs.
Even with a small space (integration into machine tools, material storage...) and by hoists with limited load-bearing capacity, productivity and performance are still increased. Crane capacities are optimized by simple mounting on the crane. Only one operator is required to move the load vertically and/or horizontally. The load is always anchored and raised from above, i.e. the lifting system is always placed on the piece from above. There is no mechanical impairment of the piece. Lifting and transporting operations are ensured completely safely (with triple safety), i.e. the pull-off force is 3 times the recommended lifting force. This is particularly important in the case of rough, scaled surfaces, because a considerable air gap can occur. The shift lever is stable, i.e. there is no rebounding of the shift lever.
Compared to mechanical alternatives, magnets bring decisive advantages in the lifting, transport and clamping of ferromagnetic pieces.

Should I switch by hand or electronically? Is it always the most expensive? When and where do I use which load lifting magnet? These are the essential questions that we have had to answer about ASSFALG magnets. A selection of our articles from different product classes will help you in your choice and show you the advantages and disadvantages of the different load lifting magnet types.
Elift – the universal type
The universal permanent load lifting magnet Elift, which can be switched by a hand lever, is ideally suited for vertical and horizontal operations, for short, flat (from 15mm) and round pieces, and at an application temperature of up to 80°C. Our Elift HOT lifts up to a temperature of 500°C.
SB 950-SF – simply modern
The SB 950-SF is the first electro-magnetic battery lifter to indicate to the operator, on the display, which load it can safely lift during the lifting process. The power electronics calculated this data within seconds and automatically while putting the magnet on the work piece. Sheets from 4 mm thickness can also be lifted off the stack individually. Even magnetizing and demagnetizing of the electropermanent battery magnet can take place automatically.
All the lifting magnets used for crane operations must have the safety factor 3 in Europe. This is often indicated with the designation SWL 3:1 (safe workload). This means that a 500 kg device must have a breaking load of at least 1,500 kg. To ensure safety permanently, annual UVV tests should be carried out.
The price of a permanent load lifting magnet depends, on the one hand, on which pieces or a round or flat material must be lifted and transported, and, on the other hand, on the quality and quality of the pieces/material.
AlNiCo-Magnets (surrounded by coil) can be magnetized as N-pole or S-pole by a current impulse (Graphic 1 + 2). The AlNiCo-Magnets are exactly opposed to the polarization of the Neodym Permanent Magnets with the magnet being switched OFF (Graphic 1).
The AlNiCo-Magnets are rectified to the polarization of the Neodym Permanent Magnets with the magnet being switched ON (Graphic 2). Electropermanent magnets keep their magnetized condition.
