Dual-Ratio Planetary Drive

The GFT 45 T2/T3 is a dual-ratio planetary drive.

It functions as a two-stage drive for low-ratio (high-speed) operation and the third stage can be engaged for high-ratio (low-speed) operation. It produces maximum intermittent output torque of 45,000 N-m and maximum output speed of approximately

150 rpm. Advantages include a wide speed range and the ability to offer two different reduction ratios in one package. It can shift on-the-fly between reduction ratios, and operates at high speeds without the need for external cooling.
