The hydraulic lifting magnet can be employed for lifting, holding and drop off ferrous parts - mostly thick-walled sheets and profiles - using mobile combustion engines. The applications are varied and range from public works, road construction, gardening and recycling to the track construction. The magnet is connected directly to the external hydraulic system and will be operated directly from the driving cab. Thanks to the permanent magnetic field, the energy is always available, the hydraulic oil flows only during the switching operations. This increases safety, saves fuel and protects the environment. Therefore, the device requires no electrical power, neither for the operation nor for the control. A battery is also waived.
