At Ligna 2019, in Hanover, Sennebogen will showcase a new electric drive version of the diesel hydraulic Pick & Carry material handler Sennebogen 735 that is so popular with the timber industry. The prototype is currently being field tested and will be ready to go into production by the end of 2019, as the company says in the press release received by Lesprom Network.
The 7 series machines have been designed to run continuously. Electric solutions, such as those typically used in stationary timber manipulation, have not been possible due to the long travelling distances involved. At ligna, Sennebogen will present the first machine with a new drive concept. All the work process still operate hydraulically, driven by an efficient stage 5 diesel engine, whilst the undercarriage travel drive is electric.
Bosch Rexroth and Sennebogen, long-term partners in drive and application technology for material handlers, collaborated to develop this electric travel drive. The system solution is based on Bosch Rexroth components, is being jointly developed into a marketable product, and will be launched by Sennebogen under the name 'Green Efficiency Drive'. The Pick & Carry material handler 735 E will be the first machine to contain the series production technology for electric travel.
