GFT & GFB Series Planetary Drive Gearbox

Introductions

The GFT and GFB series are planetary reduction gearboxes designed to convert high-speed hydraulic motor output into lower-speed, higher-torque mechanical drive. Their compact coaxial structure allows a high reduction ratio and high load capacity within a relatively small installation envelope. This makes the series especially suitable for travel drives, track drives, wheel drives, winches and other hydrostatic drive systems where durability, compact packaging and dependable torque transmission are required.

GFT Series

The GFT series is commonly used as a travel or drive gearbox for tracked and wheeled mobile machinery. It can be integrated with matching hydraulic motors and braking solutions to form a compact drive assembly. Available size options include GFT 17, 24, 28, 32, 50, 60, 80, 110, 220, 260 and 330, with different ratios and interfaces available according to the required machine configuration.

GFB Series

The GFB series provides a heavy-duty planetary gearbox solution for applications requiring strong torque output and robust construction. Typical configurations include GFB 65 and GFB 84, together with other application-specific versions. Selection should be based on output torque, reduction ratio, input motor, mounting dimensions, brake requirements and the machine's duty cycle.

Key Features

• Planetary reduction design with high torque density and compact overall dimensions.

• High radial and axial load capability for demanding mobile-machine drive systems.

• Multiple reduction ratios, sizes, mounting options and hydraulic motor interfaces.

• Suitable for integration with braking systems and hydrostatic drive arrangements.

• Robust housing and internal gear set designed for heavy-duty operating conditions.

• Flexible selection for travel drives, wheel drives, winches and other rotary drive functions.

• Wide model coverage for replacement, maintenance and new equipment projects.

Typical Applications and Brands

Typical applications include excavators, drilling rigs, crawler machines, road pavers, rollers, mining equipment, cranes, lifting machinery, industrial equipment, marine and port machinery, and other machines using hydraulic travel or rotary drive systems.

Selection Information

For accurate replacement or project selection, confirm the complete gearbox model, reduction ratio, output torque requirement, hydraulic motor model, input interface, mounting dimensions, brake configuration, output flange or shaft style, rotation direction and machine application. GFT and GFB versions can differ significantly in ratio, dimensions and motor connection, so complete model-code matching is recommended before ordering.
