Page 6 - Linde - HMF/A/V/R-02 Hydraulic motors for closed and open loop operation

Transmission concept.

Equipment manufacturers profit by the Linde Hydraulics transmission concept. Due to the direct conversion of the prime mover
speed into wheel speed it is possible to reduce the number of drive line components and the energy losses in the operating cycle.
