The system solution, based on Bosch Rexroth components, was jointly developed into a marketable product, and was launched by SENNEBOGEN under the name ‘Green Efficiency Drive’. The Pick & Carry material handler 735 E is the first machine to contain the series production technology for electric travel.

While the machine is moving around the log yard, the diesel engine drives a generator, which generates the necessary electricity for the electric engines.  During deceleration, the electric drive engines act as generators. This means that they supply the auxiliary equipment with the energy required and relieve the diesel engine. The recuperated energy can even be stored for a short time, increasing the drive power.

Another advantage is that the use of modern components in the electrical system reduces heat loss. This can also save engine power for system cooling and achieve higher working dynamics.

Over the entire product life cycle, the 735 GED saves up to 30% energy with the same performance level and therefore saves operating and service costs on a large scale. Rightsizing the engine makes it possible to save on the machine’s consumption and thus also on emissions. Vibrations and noise are also significantly reduced – for pleasant and quiet operation, which relieves strain on people and the environment in the long term.
