HMX 1100 - is a complete hydro-mechanical, continuously variable transmission (HMCVT) for tracked vehicles up to 21 ton with engine ratings of up-to 400HP. The HMX 1100 is infinity variable for both forward reverse directions and are fully capable of equal speeds. A particular feature, not seen in conventional tracked-vehicle transmission systems, is the consistent response of steering control irrespective of the direction of travel as well as hydrostatic braking which ensures long life and reduced brake maintenance.
