Electrical Components in the MBB PALFINGER System
The high-current path between the vehicle network and the Hubfix power pack is switched by main relays, solenoid switches and power relays. They carry the inrush current of the pump motor and come in different sizes depending on the load class and Hubfix generation. Burnt contacts, sluggish switching or a missing pump start despite active operation are typical signs of wear in the switching path – often the replacement of a single relay or solenoid switch is enough for full restoration of function.
The operating and signal side comprises hand-cable switches, radio remote controls and foot switches, together with limit switches as well as fuses, terminals and the associated wiring. Operating elements capture the user command, while limit switches report the end positions lift, lower, open and close back to the control unit. Wiring harnesses and plugs link the components into a closed signal loop – at transitions to the platform and at the rear portal a targeted check for corrosion and mechanical damage pays off.
The MBB PALFINGER electrical range comprises several hundred individual parts across all capacity classes and model years. Key component groups include:
- Main relays, solenoid switches and power relays
- Hubfix-specific control boxes in various designs
- Hand-cable switches, radio remote controls and foot switches
- Limit switches, fuses, terminals and wiring
In addition, we supply wiring harnesses, plugs and connectors, fuses, control elements, warning lights and numerous further components for diagnostics, repair and modernisation.
