Push-rod ventilation

Whether rail or swing vents, at Lock you will find a complete range of LZG and UBL rack & pinion gear units for Venlo greenhouses that are perfectly matched to the EWA range of power drives.

These are the advantages of the LZG rack & pinion gear units:

  • Compact, stable cast housing, from 10,000 N with hardened gear components.
  • LZG 20 and LZG 24 have the same gear ratio and can therefore be used in combination.
  • Simple, standardised assembly for fast installation times.
  • The extremely high torque ratings of the Lock power drives, therefore fewer drives required in each greenhouse.
  • Ventilation with and without insect neting possible.

Our speciality involves the ventilation systems on open-roof greenhouses that can be closed within 2 minutes with the TurboLogic system.
