The manual lifter of the MaxX Tecnomagnete series represent an ideal solution for moving ferrous loads in an economic, rapid and safe way.
RAPID
With the simple motion of a lever, the magnetism lifts, transports and releases the load with extreme rapidity, needing only a single operator. It does not compress or deform the load, rather, it allows plenty of motion even with limited spaces.
SAFE
Once activated, a spring-loaded device blocks the manoeuvring lever, thus preventing any possible accidental deactivation. The technique defined as neutral crown will not permit interference with the original state of the permanent magnets, thus allowing to obtain maximum results in terms of safety and reliability.
ECONOMIC
The Tecnomagnete manual lifters are based on the technology of permanent magnets, therefore do not need electrical feeding. They are resistant to usage: the only movable component present is a rotor which is centred on ball bearings. This in turn develops neither physical contacts nor any friction during the rotation phase. Within normal working conditions they can be “maintenance free” over a long period of time. |

LONGITUDINAL ELECTRO LIFTING MAGNETS
These magnets are used to lift bundles of material with an irregular surface, which complicates lifting operations. Longitudinal magnets, however, have a particularly deep penetration field that makes them unsusceptible to such irregularities. This enable safe and effortless transport of bundles of material. Moreover, two or more of these magnets can be used, depending on the length of the bundles. In the event that people are present in the lifting area, however, extra mechanical slings must be fitted for safety purposes.

BAT GRIP
3 Ton capacity permanent-electro lifters with battery.
Equipped with a remote control, this lifter is capable to be used for a long period independent of the power supply (est 7
days), because the energy is only used for a fraction of a second during the MAG/DEMAG phase. |

The use of electro & permanent lifting magnets offers the following advantages:
- Speed, simplicity and the damage-free transport of workpieces of various
shapes and lengths.
- The possibility of precisely positioning the workpiece to be lifted
- Saving valuable storage space and manpower
All magnets can be supplied with electronic control. The control is equipped with an IGBT that switches the current to the magnets. Both voltage and current can be set at, for example, 80-100 and 120% for lifting, transport and compression.

Electropermanent magnets utilize permanent magnetic material surrounded by an electrically powered coil. To energize an electropermanent magnet, a momentary pulse of D. C. power is applied to the magnet's coil in order to charge the permanent magnetic material within. Once energized, the electropermanent magnet does not require a constant source of power to retain the lifted steel coil. To release the steel coil, a reverse pulse of D. C. power is applied to the magnet's coil. The Electropermanent magnet design tends to excel when the steel coil's edge stagger is kept to a minimum.
Special Adaptations (Standard Circular, Rectangular, and Bi-Polar)
Able to prevent "telescoping"
Less storage space required
Transport requires less manpower |
|
Features:
Cold Operation
Since the electrical current is only used momentarily, no insulation or coil failures are caused by internal heating.
Safer Holding
The permanent magnetic material is unaffected by external power failure. Since Electro-Permanent magnets require electricity only to activate the magnet "on" or "off", there are no mechanical parts that could accidentally stick. Once the magnet is "on" the electricity can be disconnected indefinitely without any interruption to the holding power.
Cycle Time
Energizing the magnetic material typically takes 2-3 seconds.
Power Consumption
Operating costs are very low compared to conventional electromagnets because the power is applied for a minimal time. |

ROUND LIFTING MAGNETS
Electromagnets are intended for lifting mechanisms to catch and shift the cold ferromagnetic loads: scrap metal, charge, cuttings, metal bars, pigs, slabs, etc.
These lifting electromagnets can operate on the traverse.
Electromagnets are recommended for installation on light and mobile excavators such as FUCHS, LIEBHERR, ATLAS, SENNEBOGEN, CAT, ZEPPELIN, KOVROVETS etc. complete with a generating control system and a special traverse that ensures the use of an electromagnet without removing the grab.
All electromagnets can be produced as heat-resistant (to lift loads of the temperature as high as 600°C) and for underwater works. |

SafeHold® Permanent Lifting Magnets
Lift up to 10,000 lbs (4,536 kg). Compact permanent magnets lift and transfer steel and iron without slings, hooks or cables.
Selecto® Electro Lifting Magnets
The SL Series requires a compact Eriez variable-voltage rectifier controller or a fixed voltage rectifier to furnish the desired D.C. power from any A.C. source.
Bi-Polar Lifting Magnets - Rectangular
Specifically designed to provide greater contact and holding strength on castings, forgings, plates and structural shapes.
Bi-Polar Lifting Magnets - Square
Especially deep field provides greater holding on steel coils, bundles of bar, re-bar, tubing or pipe.
Rectangular Lifting Magnets
Three standard models, and lengths from nine inches (229 mm) to 96 inches (2,438 mm), allow you to size the magnet to the job. Eriez' smallest single unit has a holding power (with no safety factor) of 1,860 (845 kg; the largest, 38.8 tons (35,240 kg).

CM-400, CM-800 TOTERS
The TOTER is a compact, self-contained, lifting magnet which uses permanent magnets that maintain holding power indefinitely. Within the steel housing are powerful ceramic magnets whose field is controlled by the "on-off" position of the handle. Because no electric power is required, TOTERS can operate completely free of the restriction of power cords, and can be used where electric power is not readily available.
Recommended Applications
Permanent lifting magnets require good surface conditions to achieve maximum lifting.The TOTER is ideally suited for in-plant handling, loading, and unloading machine tools, and is commonly found in industrial plants, machine shops and warehouses.When greater holding capacity is required, refer to our battery magnets or our circular electric magnets.
Rated Lift Capacity
The maximum rated lift is based upon lifting clean, smooth, flat, low-carbon steel plate, 1 1/2" or thicker with the full area of the magnet's lifting surface in contact with the load. Derating is required for plates with rust or scale, plates thinner than 1 1/2", and alloy steels. More detailed ratings are contained in the OPERATOR'S MANUAL AND SAFETY INSTRUCTIONS. |

RECTANGULAR LIFTING MAGNETS
Electromagnets are intended for lifting mechanisms to catch and shift the cold ferromagnetic loads: sheets, squares, channels, rails, blooms, slabs, etc.
These lifting magnets can operate on the traverse and are recommended for installation on light and mobile excavators such as FUCHS, LIEBHERR, ATLAS, SENNEBOGEN, CAT, ZEPPELIN, KOVROVETSetc. complete with a generating control system and a special traverse for loading sheets, sguares, channels, rails, blooms, slabs and the like.
All electromagnets can be produced as heat-resistant (to lift loads of the temperature as high as 600°C) and for underwater works. |

MAGVACU® COMBIGRIPPER
The MagVacu® combigripper uses a combination of magnetic and vacuum techniques for the handling of (perforated) sheet up to a thickness of 12 mm.
Re-tooling for different products is not necessary so that more types of products can be handled on unmanned machines. The Combigripper is also twice as powerful as, and safer than, conventional vacuum systems. The magnet pulls the steel plate onto the vacuum suction cup so that it fits neatly onto it. This means that no vacuum can leak away around the edge of the suction cup
The universal combigrippers can be used:
in automated processes on laser cutting machines
in press brakes and press transfer systems in
the car and sheet metal work automotive and plate processing industries
