Infinitely economical: ecospeed & ecospeedPRO


ecospeed is an infinitely variable and hydrostatic high speed transmission that was co-developed by Kramer. It offers maximum efficiency in combination with the best possible environmental compatibility. Ecospeed "thinks" and optimises the interplay of driving performance, traction, fuel consumption and emissions every second.

ecospeed translates the situational requirements into quick and direct accelerations and into gentle and smooth changes of direction. This provides for particularly high material handling performance with simultaneous resource conservation. A big plus for applications that occur day after day when loading and unloading lorries and also a gain in comfort and time that pays for itself from the beginning.

The ideal translation of the requirements of today into the practice of tomorrow:

  • Variable from 0 to 40 km/h
  • Minimised fuel consumption
  • Low noise emissions


We have further developed the ecospeed transmission for our larger machines. The ecospeedPRO transmission achieves higher tractive forces and travel speeds while retaining all the advantages of the ecospeed transmission in terms of compactness, energy efficiency and operator comfort. The increase in traction and shear force is achieved by a larger design and thus a 39 % larger displacement volume of the variable speed motor (370 cm³). The intelligent "Smart Driving" motor speed reduction is integrated as standard in the ecospeedPRO travel drive.

ecospeed / ecospeedPRO - The drive for more efficiency

  • Maximum shear force and tractive force in all driving and working situations
  • Self-propelled unit when used on nearby construction sites. Expensive machine transport to the site of operation is not required
  • Reduction of the fuel consumption
  • Reduced noise emissions from working in the optimal characteristic range of the diesel engine
  • Easy hill starts, even with a heavy load

ecospeed / ecospeedPRO - The drive for more comfort and safety

  • Sensitive control of the machine
  • Variable drive, no shifting required
  • Speed control from 0 - 40 km/h that is completely jolt and shock-free
  • Intelligent technology for maximum safety: the maximum speed can only be achieved in front steer only mode
  • Automatic braking when going downhill, thereby protecting the drive system from over-revving
  • Safety through simple travel direction selection on the joystick
  • Simple handling, no risk of operation errors
  • Perfect manoeuvrability, in particular when reversing, accelerating and braking
