The Advanced Technology of Electro Permanent Lifters

Electropermanent systems represent a significant advancement in magnetic lifting technology, combining the best features of both permanent magnets and electromagnets. Unlike traditional electromagnets that require continuous power to maintain their magnetic field, Electropermanent Magnets utilize a clever design involving both permanent magnets and electromagnets. This innovative approach means there is no need for a battery system in the magnet itself, nor is continuous energy supply required to maintain its hold. When the product is in operation and the uninterruptible power supply is powered off, its magnetism remains actively engaged for a long time without consuming any energy. This inherent fail-safe design ensures that the load is never dropped due to power failure, providing an unparalleled level of safety in industrial environments.

The operational cycle is remarkably efficient: to magnetize and lift a ferromagnetic (iron) part, a short electrical pulse is applied. The system then “locks” into its magnetized state, holding the load securely without further power consumption. To release the load, another brief electrical pulse is applied in the opposite direction, which neutralizes and demagnetizes the unit, releasing the held piece. This magnetization and demagnetization cycle is incredibly fast, typically taking approximately 1-2 seconds. Such rapid and controlled operation provides serious time savings, significantly preventing loss of work in terms of both the transport and release times of heavy ferromagnetic parts.

Thanks to these distinctive features, the power of the electromagnetic can be precisely controlled, allowing for an on-off system that, combined with the permanent magnet principle, ensures the maximum level of safety for both the operator and the machinery. These systems are specifically designed to safely and efficiently carry sheet metal, coils, and other heavy ferromagnetic materials, often allowing a single operator to manage the entire process with remote control, thereby eliminating the need for additional human power and enhancing operational efficiency and safety.

Working Principle:

The EPT-ST/TT Series employs the same reliable electropermanent principle: a brief electrical pulse magnetizes the system, securing the load. Its magnetism persists even when power is cut, guaranteeing fail-safe operation. A subsequent pulse demagnetizes the system, releasing the piece (MAG-DEMAG). What sets this series apart is its integrated telescopic movement, driven by a specialized hydraulic pump. This telescopic action allows the arms to extend or retract, enabling the efficient handling of a wide range of sheet metal lengths. This flexibility is critical for optimizing material flow in dynamic industrial settings.

• *For shorter plates, only the middle cross Electropermanents can be activated. This optimizes power consumption and precise handling for smaller loads.
• *All cross Electropermagnet Plates can be activated when the side modules for the middle plates are in the off position. This allows for intermediate length plates.
• *For long plates, all cross Electropermanent Plates are activated and must be used with the arms extended to the maximum opening. This ensures full magnetic coverage and stable lifting for the longest materials.
• *Activate only the left or right side modules for narrow plates. This provides granular control, allowing the system to adapt to varying material widths and shapes.

Features:

• Uninterrupted Hold: Critical for safety, it does not release the material in power cuts, safeguarding both personnel and valuable materials.
• Superior Safety Standards: Engineered to provide the maximum level of safety for the operator and the machine, mitigating risks associated with handling heavy, large format sheets.
