Drives for trunk lids and tailgates: effortless handling of heavy loads

  • Short opening and closing times
  • Freely programmable force limits and stop positions

The weight of passenger car trunk lids and tailgates is frequently high. And the larger the vehicles, the heavier these components become. The hydraulic drive systems made by HOERBIGER allow them to be moved effortlessly.

All components of the hydraulic drive units are available as modular systems. Depending on the customer requirements, the drives are also available as complete systems – minimizing our customers’ installation time. Power units, cylinders and valves can be customized to individual applications. The efficient hydraulic system ensures swift fluid motion when powering open or closed. Internal force limiting valves in both directions of travel can be independently set to guarantee that the vehicle structure is not subjected to extraneous force, while integrated sensors allow the stop position to be programmed at any position of travel.
