Auto Downshift Function

Controller monitors engine speed, travel gear and travel sped. When load is applied and machine travel speed is reduced, the transmission automatically downshifts to optimum gear speed to provide high fuel efficiency. This function provides comfortable operation without manual downshift and high productivity.

Automatic Torque Converter Lockup System

For greater efficiency during long pushes, the lockup mode allows the system to automatically engage the torque converter lockup clutch. Locking up the torque converter transmits all the engine power directly to the transmission, increasing ground speed and thus achieving efficiencies equal to a direct drive. The result is efficient use of engine power, less fuel consumption, and faster cycle times.

K-Bogie Undercarriage System

K-Bogie undercarriage system combines prior advantages with additional features. K-Bogies that oscillate with two fulcrums assure large amount of track roller vertical travel. Impact load to undercarriage components is minimised and durability of components is improved since track rollers are always in contact with track link.
