Helical gearbox for bulk goods wagon of type Tanoos

We have developed a special helical gearbox and roof gearbox for manually opening and closing bulk goods wagons. Our gearboxes offer various advantages compared to other solutions:

  • Rapid emptying of the cargo
  • Maximum safety for the operating personnel through the newly developed gear brake for softened closing of the slides. Even stiff slides can be moved in a controlled manner. The brakes work in relation to the closing load
  • Low actuation forces thanks to high efficiency of the gearbox of 98 % and large ratio
  • Corrosion resistant as a result of thick-coat paintwork as well as special materials
  • Easy machine cleaning by avoiding dirt-collecting corners
  • Maintenance free thanks to permanent oil filling




Driven by ideas


Often the work of our engineers starts with a LEGO model.
