The drive system for ventilation louvres.

One application involved a 1,450 m2 area of glass panels (louvres) on the curved glass facade of the Königsbau Passage, a shopping mall in Stuttgart, while another called for solar protection and SHEVS on the remarkable Stadtlagerhaus in Hamburg: in both cases, the technical specialists responsible decided in favour of rack drives from Lock.

The patented rack drives, some recently developed and configured for these particular buildings, are impressive performers – no matter which variant – by virtue of their ease and low cost of assembly, their long service lives and their absolutely reliable mechanical synchronization.

Performance features:

  • Extremely robust special rack drive
  • Robust aluminium housing
  • Quality ball bearings for almost silent operation
  • Self-locking worm gear unit
  • Original “Made in Germany” products
