Part FAQ

Frequently asked questions about this part

  • A door balancer averages 15,000 to 25,000 cycles, i.e. 1.5 to 2 years at 40 cycles/day. The spring fatigues, the wire corrodes and loses effective diameter. Monitor it: if the door takes more force to open than to close, increase tension. If the reverse, reduce it. Past 2 years, schedule a preventive replacement — a spring breaking in service is dangerous and immobilises the vehicle.

  • The DoorLIFT operates the door only when the force required to open or close it stays under 35 kg. Before installation, check the door opens and closes manually with comparable force in both directions. If it takes more force to open, increase balancer tension. If more to close, decrease tension. A poorly balanced door wears out the motor block prematurely.

Field essentials

Two essentials to know before anything else

Critical procedures to stay operational — emergency release and installer qualification.

  • External release procedure: (1) insert the DoorLIFT key into the lock cylinder at the centre of the intermediate or top panel, outside face; (2) turn the key 90° clockwise and firmly pull the lock and cable out of the cylinder — the system disengages; (3) reinsert the cable and cylinder into the door lock housing, then operate the door by hand. On the AluLIFT, an internal release is available: pull the red sleeve marked 'EMERGENCY DOOR RELEASE' to disengage the motor lever from inside the box.

  • VanDOOR does not perform installation itself. AluLIFT integration must be carried out exclusively by qualified, trained bodybuilders or integrators, in accordance with Machinery Directive 2006/42/EC and best practice. The integrator guarantees regulatory compliance of the final assembly, verifies correct operation, commissions the system, and supplies the end user with the manual and CE Declaration of Conformity for the integrated equipment.
