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.

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. 
   

4. 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.
