The Hydrostatic Drive is used in IC-engine fork lift trucks. It is mostly found in All Terrain Trucks.  .

The Hydrostatic Drive consist of a high-pressure piston pump which is powered directly by the IC-engine of the truck. This pump is connected via high-pressure hydraulic hoses to the wheel motors (hydro-motor). The lift of the motor pistons is transformed into a rotating motion inside of the wheel motors. The rotating motion is transmitted by gear reduction to the drive wheels of the truck.
