The PMB 2400 consists of four components: the magnet system, the top cover of the magnet system, two parallelograms with lifting and lowering cylinders and the equipment plate. The magnet system used in the PMB 2400 is very powerful and user-friendly. The strongest magnetic fields are directed downwards, while the magnetic fields to the side and upwards are significantly weaker, ensuring it complies with appropriate safety limits. The permanent magnetic beam is guided evenly over the traffic surface by two wheels. It reliably picks up magnetic objects at a working width of 2,400mm and a field density of approximately 300 Gauss, at a ground clearance of 100mm. The PMB 2400 is attached to the vehicle plate of the carrier vehicle by a quick-change system and can be attached or removed within a few minutes on size three and size five vehicle plates.
Magnetisable foreign parts are attracted when the PMB 2400 drives over them and remain firmly attached to a stainless steel rail, but the field lines of the magnet can still pass through it. The magnetic bar can be raised and lowered via the vehicle hydraulics or the independent electro-hydraulic system.
The transport position is reached via the lifting and lowering cylinder, and ground clearance in transport mode depends on the carrier vehicle used. When the magnetic beam is lifted, the stainless steel rail can be swung downwards, so that any foreign objects are no longer subject to the influence of the magnet and can be disposed of accordingly. The maintenance of the PMB 2400 is limited to periodic checking for damage and possible lubrication of the sliding parts.
