VanDOOR Aluminum

The AluLIFT is intended for light commercial vehicles, trucks and trailers with a cargo compartment, providing motorised cargo opening and closing. Two connection-plate variants are offered: insulated for refrigerated vehicles, standard for dry boxes. Operation is strictly limited to a stationary vehicle — driving with the door open is forbidden. Insulated trucks or trailers need a roof reinforcement before rail mounting.

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.

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 DL-6 has an S3 20% intermittent duty cycle: 2 minutes of continuous use max, followed by 8 minutes of rest to dissipate motor heat. In practice, an open/close cycle lasts ~28 seconds for a 2.5 m door — well below the threshold. On a standard delivery round (40 cycles/day), the duty cycle is respected without precaution. Risk of exceeding only with intensive industrial use (testing, repeated loading).
