Drum drive ( GFT17) DH/PDH-versions
On the DH/PDH-versions the drum is driven by a fast rotating axial piston motor 51D110 from Sauer
and a reduction gear GFT17 from L Stolterfoth.
The function of the axial piston motor is identical with the function of the axle drive motor and does
thereofre not need to be explained in detail.
A reduction gear with a reduction ratio of i = 53.95 reduces the high output speed to the final rotational
speed of the drum.
