The GFT330T3 is a heavy-duty hydraulic travel drive designed for tracked construction machinery, crawler equipment and other mobile machines requiring high-torque track drive transmission.
The travel drive integrates a hydraulic motor interface, planetary reduction gearbox and braking system into a compact final drive assembly. The listed configuration provides a maximum output torque of 330,000 N·m, with multiple reduction ratios and hydraulic motor options.
The final configuration should be selected according to required output torque, reduction ratio, hydraulic motor, brake requirements, machine weight, travel performance, mounting dimensions and operating conditions.
Hydraulic motor: The input drive can be configured with selected hydraulic motor options.
Planetary gearbox: The reduction stages convert hydraulic motor input into the required track drive output speed and torque.
Integrated brake: The drive includes a braking configuration for tracked equipment.
Mounting interface: The final drive is installed between the machine structure and track drive system according to the specified mounting arrangement.

The GFT330T3 is available with reduction ratios of 169, 210, 252 and 302. The selected ratio affects the relationship between hydraulic motor input speed and final drive output speed.
The listed configuration includes A2FE160, A2FE180, A2FE250 and A2FE355 as well as A6VE160, A6VE250, A6VM200 and A6VM355 motor options. Final compatibility should be confirmed according to the motor interface, displacement and hydraulic system.
The travel drive is specified with a maximum braking torque of 2,500 N·m and brake pressure of 1.8–5 MPa.
With a maximum output torque of 330,000 N·m, the GFT330T3 is intended for heavy-duty tracked machinery and high-load travel drive applications.
The GFT330T3 hydraulic travel drive can be used in tracked equipment where high output torque and hydraulic final drive transmission are required. Typical applications include:
Heavy-duty tracked construction machinery
Large crawler machines
Mining and material-handling equipment
Heavy crawler cranes
Special-purpose engineering vehicles
Other high-load tracked mobile equipment
Travel drive selection should be based on the complete machine and hydraulic system rather than output torque alone. The following parameters should be confirmed before selecting a final drive:
Machine operating weight and required traction
Required travel speed
Required output torque
Hydraulic system pressure and flow
Hydraulic motor displacement and mounting interface
Reduction ratio
Brake torque and brake pressure
Track sprocket interface
Mounting dimensions and available installation space
Working conditions and duty cycle
Machine drawings and existing final drive dimensions are recommended for replacement projects because mounting and interface compatibility must be verified before installation.
The GFT330T3 can be evaluated for OEM equipment development and hydraulic final drive replacement projects. For applications based on existing travel drive systems, the replacement should be checked against the original torque rating, reduction ratio, hydraulic motor interface, brake configuration, mounting dimensions and sprocket connection.
Where a replacement is intended for a specific branded travel drive, compatibility should be confirmed through technical drawings and interface dimensions rather than model name alone.
Original travel drive model
Machine model and operating weight
Hydraulic pressure and oil flow

Required travel speed
Required reduction ratio
Brake requirements

Correct lubrication, hydraulic cleanliness and regular inspection are important for reliable final drive operation. Maintenance procedures and service intervals should follow the technical documentation for the selected configuration.
Check gearbox oil level and condition according to the specified service schedule.
Inspect hydraulic connections and seals for leakage.
Check mounting bolts and output connections.
Monitor abnormal noise, vibration or temperature changes during operation.
Inspect the sprocket and track connection for wear.
Use the recommended lubricant and maintenance procedure.
Payment: 30% deposit and 70% before shipment. Payment terms can be negotiated, generally by T/T.
Delivery: 20–25 days after receipt of payment.
Service: 24-hour online service and overseas technical support.
