Hydraulic magnets are big scrap lifting magnets which directly connect to the excavator’s hydraulic pipes.
They need a constant-flow but they have their own independent power generator and they works without any additional electrical box installed.
They are used for lifting and handling large magnetic materials and they are common in scrap collection centers, in demolition companies and in recycling yard.
Valuable hydraulic magnets have to be safe, durable, mobile and easy handling. Better if they are equipped with valves to control the pressure and the oil flow. They might also have a device for quick release of the material, like GIDA hydraulic magnets!
