Hydraulic Drive - Model 8080 Hydraulic Drive Rail Gear
Mitchell Model 8080 Hydraulic Drive Rail Gear for medium Hydraulic Excavators with base weights of 60,000 lbs. to 80,000 lbs. The system is available in kit form or Mitchell Factory Install. The Hydraulic Rail Gear Drive system consists of front and rear mounted hydraulic drive axles that are driven off the excavator hydraulic system. The drive axles can be geared for various speeds and torque capabilities.
The front and rear hydraulic drive axle assemblies pin to the provided Rail Gear fixed frame that is welded to the excavator car body. Both front and rear Rail Gear axles are driven by heavy duty hydraulic motors. Hydraulic Hoses that normally connect to the rear excavators drive motors are re-routed to the Mitchell control valves and new hydraulic hoses are connected between the Mitchell control valves and the excavator rear drive motors.
Both front and rear hydraulic drive axles are equipped with ride control thats acts as a shock absorber for dampening forces from traveling on uneven railroad track. This helps to stabilize the entire machine on rail.
The Rail Gear drive system can be controlled with manual valves located on the rail ger or optionally in-cab controls.
