The safe solution for industrial lifts also used for transporting passengers

Convincing and practice-tested

MEILLER has the solution for all retrofitting requirements involving industrial lifts used to transport passengers that are still operated without car doors.

Whether for modernisation or a new installation, MEILLER’s GENIUS® Plusi is both ingenious and simple:


The torsion springs are mounted inside of the drive gearbox, thus ensuring that space needed for the roller shutter door is minimal. All necessary changes to the existing car can be made quickly and with minimum effort. This considerably reduces installation and modernisation costs.


The GENIUS® Plusi roller shutter door is combined either with a MEILLER swing door from the DT3X series or a standard retail swing door. An unlocking cam is optionally available and is installed on the door, actuating the locking mechanism.


The door slats are made of 1mm thick aluminium strips and are coated with a metallic anti-friction coating, which guarantees an appealing look and a high wear resistance. As of a door width of > 2800 mm, the slats are supplied in a reinforced version. A light curtain may also be used as a closing edge safety, completing the entire modernisation.

Vertical door advantages:

  • Low weight and largely resistant to corrosion, since parts are primarily made of aluminium
  • Torsion springs inside the drive gearbox, minimising the amount of space required
  • No risk of lateral crushing
  • Ideal for forklifts, since there are no troublesome door sills
  • Easy to install
  • GENIUS® Plusi complies with EN 81-20/50.
