Hitachi EX60-1 EX60SR Excavator Final Drive 9069295 9096479 9138927 hydraulic travel motor

Structure & Function

The excavator travel assembly is the core component for machine movement, consisting of a hydraulic motor, reduction gearbox, sprocket, track chain, idler wheel, carrier roller, and track roller. Its key function is to convert hydraulic energy into mechanical power, enabling stable mobility across challenging terrains.

1. Hydraulic Power Transmission

   • The hydraulic pump transforms engine power into high-pressure oil, which is transmitted to the travel motor via hydraulic lines.

   • The travel motor converts hydraulic energy into rotational kinetic energy, generating high-speed, low-torque output.

   •  

2. Speed Reduction & Torque Amplification

   • The gearbox reduces motor speed through gear sets while significantly increasing torque, ensuring sufficient traction force for the sprocket.

   •  

3. Track Drive Mechanism

    

   • The sprocket engages with track links to drive the track chain. Carrier rollers and track rollers form a closed-loop track system, while the idler wheel adjusts track tension.

   • Differential control of dual travel motors enables forward/reverse movement, steering, and zero-radius rotation.

   •  

Technical Advantages

• High-Efficiency Power System: Precision hydraulic motors paired with heavy-duty gearboxes deliver 30% higher torque output, ideal for slopes, swamps, and harsh conditions.

•  

• Extended Durability: Manganese steel + rubber composite tracks enhance wear resistance by 50%, with a service life exceeding 8,000 hours.

•  

• Smart Control: Optional electronic speed modulation enables stepless speed adjustment, balancing productivity and fuel efficiency.

•  

Applications
Suitable for mining, earthwork, municipal projects, and mountainous terrains. Operational temperature range: -30°C to 50°C.
