Previous Version
With chains and springs to open and close the flaps, the previous design is less durable than the updated version.

Updated Version

  1. Flaps are opened and closed by a connecting rod and “arms” connected to the gear motor
  2. The new flaps provide a stronger grip on the bag
  3. The rugged shaft used for the up and down motion reduces maintenance costs to a minimum


  • Reduced noise when the flaps get back to the upper position.
  • Reduced risk of broken shafts.
  • Rugged design for lower maintenance costs.
  • Less adjustments required
