Product Description
Rexroth GFT Series Planetary Gearboxes for Track & Winch Drives
Product Overview: The Rexroth GFT Series (INDREX) represents the ideal solution for travel drives in mobile machinery and winch drive systems. As a high-performance planetary gearbox, the GFT series is renowned for its extremely compact design and ability to handle immense output torques. This featured selection includes the core specifications: GFT17T2 (2-Stage) and GFT60T3 (3-Stage), covering specific models GFT17T2B45-33, GFT17T2B45-14, and GFT60T39139. Often integrated with hydraulic piston motors and multi-disc parking brakes, the GFT series is the power heart for crawler excavators, drilling rigs, crane winches, and road machinery.
Key Technical Advantages:
Extreme Power Density: Multi-stage planetary gear technology delivers massive reduction ratios and torque output within a minimal installation envelope, optimizing chassis space.
Highly Integrated Design: Seamlessly matches Rexroth A2FE/A6VE series hydraulic motors and integrates a reliable, hydraulic-release parking brake.
Superior Load Capacity: Built with a heavy-duty bearing system capable of withstanding immense radial and axial loads from tracks or winch wire ropes.
Flexible Ratio Options: Available in various configurations from 2-stage (T2) to 3-stage (T3) ratios (e.g., codes 33, 14, 139), ensuring precise speed and torque control for diverse applications.
Target Applications: Crawler travel drives, rotary drilling rig travel, crawler crane winch drives, pavers, and TBM (Tunnel Boring Machine) cutterhead drives.
Detailed Models & Parameters:
Core Series: Rexroth GFT Series (Hydrostatic Travel Drive).
