The GFT9T2 travel drive is a compact hydraulic travel drive unit designed for tracked construction machinery and other mobile equipment. It combines a hydraulic motor interface with a planetary gearbox to transmit driving torque to the crawler track system.
With multiple reduction ratios and hydraulic motor options, the GFT9T2 can be configured for different machine sizes, travel requirements and installation conditions. It is suitable for equipment manufacturers, replacement applications and customized hydraulic drive systems.
The travel drive uses a hydraulic motor as the input power source and a planetary reduction gearbox to deliver torque to the tracked vehicle drive system.
Available reduction ratios include 20, 26, 30, 36 and 45, allowing the drive configuration to be selected according to the required travel performance and machine operating conditions.
The integrated planetary gearbox provides a compact drive solution for crawler-based equipment where installation space and torque transmission requirements need to be considered together.
The GFT9T2 configuration supports A2F45, A2F55, A2F63 and A10VE45 K45 hydraulic motor options as listed in the available technical configuration.
The travel drive is available with a braking system designed for tracked mobile equipment. Braking torque and brake pressure are specified according to the selected configuration.

Proper installation, lubrication and periodic inspection are important for the reliable operation of a hydraulic travel drive. Installation dimensions, hydraulic motor matching, lubrication specification and service intervals should be confirmed against the final technical documentation supplied with the selected configuration.
Check the gearbox oil level according to the specified service schedule.
Replace gear oil according to the applicable maintenance interval.
Inspect hydraulic connections and seals for leakage.
Check mounting bolts, drive connections and external components regularly.
Use the lubricant specified for the selected gearbox configuration.
