Manual Shift

Although Mercedes PowerShift 3 automated transmissions are fitted as standard to all Arocs, there are a range of 9- and 16-speed manual gearboxes available.

Turbo retarder clutch

The Turbo Retarder Clutch provides wear free starting and braking under extreme loads. Combining the benefits of a hydrodynamic clutch and a primary retarder in a single component, it makes it possible to move away with maximum control, minimum fuel consumption and no wear – and all of this with full torque and no time limitations. 

The integral, high-performance primary retarder with braking power of up to 750 kW (1006hp), which also functions in reverse gear, reduction of some 80 kg in weight compared to a conventional torque converter clutch and the reduced noise emissions are further benefits. The reduction in wear to the braking system reduces downtime and servicing costs, as well as improving cycle times and increasing safety at weights up to 250 tonnes.

Applications that benefit from the fitment of the Turbo Retarder Clutch include:

  • Quarrying & Mining
  • Timber & Logging
  • Heavy Vehicle Recovery
  • Plant & Machinery Transport
  • Heavy Haulage

The Turbo Retarder Clutch is available in a variety of vehicle types, including tipper and rigid chassis as well as tractor units with engines from 315 kW (420hp) to 460 kW (625hp). It is also used in the Actros and Arocs SLT models, with an additional cooling package behind the cab although the benefits are also seen at much lower weights as well.
