Mobile machines
On a building site, there are no excuses –
and no second chance for a weak gearbox.

Mobile machines operate in one of the harshest environments imaginable: dust, dirt, vibrations, extreme temperatures and heavy loads – often in continuous operation on cramped building sites. Breakdowns are costly, and maintenance options are limited. Under these conditions, the gearbox must reliably transmit power – whether during drilling, lifting, compaction or transport.

CHEMNITZER ZAHNRADFABRIK develops specialized gearboxes for mobile machines that are designed for high torques, heavy loads and harsh operating conditions – robust, sealed and engineered for a long service life.

Typical requirements for the gearbox

  • Transmission of very high torques and forces during continuous operation
  • Extreme robustness against dust, dirt, moisture and vibrations
  • High sealing performance for use in dusty and wet environments
  • Ability to change gears under load for flexible operating modes on the construction site
  • Compact and weight-optimized designs for mobile machines
  • Low-maintenance designs for use on hard-to-access construction sites

What we offer

We design gearboxes for mobile machines with a particular focus on robustness, leak-tightness and power density. Our experience with hydraulic manual gearboxes, bevel-planetary gearboxes and transfer boxes for mobile machines is demonstrated by numerous completed projects. From the outset, we consider the specific installation and operating conditions on the construction site.

Typical gearbox types and application examples

  • Robust hydraulic spur gearboxes as drilling drives for specialist civil engineering
  • Two-stage bevel planetary gearboxes for mobile stone saws
  • Transfer gearboxes with integrated planetary axle differential and brake
  • Hydraulic motor gearboxes for travel and slewing drives in mobile machines

Does your construction machine need a drive system that won’t let you down, even under the toughest conditions? We’ll develop the solution.
