9301480 9301479 9270013 Final Drive for Hitachi EX1200 & EX1200-6 | Ultra-Class Mining Travel Device

The Final Drive and Travel Device Motor Assembly (P/N 9301480, 9301479, & 9270013) is the heavy-duty propulsion heart of the Hitachi EX1200 and EX1200-6 ultra-class excavators. Engineered for machines in the 110 to 120-ton range, this assembly is designed to handle staggering torque loads and provide the relentless tractive effort required for continuous operation in large-scale mining, quarrying, and heavy overburden removal.

Unmatched Reliability for Continuous Production The Hitachi EX1200-6 is a benchmark for efficiency in high-volume mining. However, moving a 120-ton asset requires a final drive that can survive extreme shock loads and relentless duty cycles. The 9301480 / 9301479 travel devices are engineered to translate massive hydraulic pressure into the drawbar pull needed to navigate steep pit ramps and unstable floor conditions.

In the mining world, if the excavator stops, the trucks stop, and the revenue stops. Our premium replacement drives are built to withstand the "shudder" and high vibrations of hard-rock environments. By utilizing induction-hardened gears and mining-grade bearings, this assembly prevents internal gear pitting and heat-related seizures. Replacing a failing drive with our precision-engineered unit restores your machine's synchronized agility and maximizes your tonnage per hour.

• Australia & North America: Built for the 24/7 high-uptime requirements of the Pilbara and the Canadian Oil Sands. These units handle the extreme duty cycles and high-pressure settings of Hitachi’s advanced hydraulic systems.

• Africa & South America: Optimized with "Mining-Grade" Duo-Cone seals to prevent the ingress of abrasive mineral dust, tropical mud, and high-salinity water in copper, gold, and iron ore pits.

• CIS Regions (Russia / Kazakhstan): Features metallurgical properties that maintain structural ductility in sub-zero temperatures, preventing housing cracks during high-torque cold starts in Siberian coal mines.

Mining Pro-Tip: On a machine the size of the EX1200, the final drive is an investment worth hundreds of thousands over its lifetime. Proper maintenance is your only insurance.

• Oil Sampling (S.O.S.): Regular oil analysis is non-negotiable. Spikes in iron, chromium, or copper levels allow you to catch a bearing failure before it "grenades" the entire 9270013 planetary set.

• Magnetic Plug Forensics: Inspect the magnetic plugs at every service. Fine metallic "fuzz" is normal; any distinct flakes or chunks mean a gear tooth is spalling. Stop the machine immediately to prevent total destruction of the housing.

• Case Drain Integrity: Ensure the travel motor's case drain line is never restricted. At these pressures, backpressure will blow the main shaft seal instantly, contaminating the gearbox oil with hydraulic fluid.

• Sprocket Bolt Torque: High-torque mining operations stretch bolts. Never reuse old sprocket bolts. Always use new Grade 12.9 bolts and follow Hitachi's multi-stage torque and angle specifications.

Guangzhou Tieqi Construction Machinery Co., Ltd. (IRON CAVALRY) is strategically located in Guangzhou's Huangpu District, approximately an hour from Baiyun International Airport. We have been a dedicated specialist in engineering machinery hydraulics for nearly 15 years.
