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)
- Type A2FE160/61W-VZL106
Speed reducer
- Model two-grade planet gear reduction (German Rexroth )
- Type GFB60T2B24-06
- Reduction ratio 34
- Brake response pressure 1.8Mpa
Auxiliary oilway hydraulic system
Open type constant displacement throttle speed governing hydraulic system is supplied oil by gear pump and controls oil liquor’s cooling and hoisting tail bracket’s lifting of the whole hydraulic system through hand operated direction valve and ball valve.
