Drive system

Closed type circuit hydraulic drive system adjusts speed through hydraulic plunger pump with bi-directional variable displacement, reduces speed through planet gear and drives pulling wheels to rotate in positive and negative directions through the first level gear terminal drive.

Cooling mode forced cooling

Main pump

Model sloping cam plate bi-directional plunger pump (German Rexroth)

Type A4VG250HDDT1/32R

Hydraulic motor

Model inclined-axis bi-directional constant displacement tapered plunger motor (German Rexroth)
