Excellence Fuel Economy

·SEM customized engine delivers optimal power and productivity
·Low speed engine design and E-fan delivers better fuel efficiency and lower noise
·Single load sensing hydraulic system supplies flow and pressure only when
required,which saves fuel by 8 % - 1 2 %
·High efficiency torque converter provides higher power transfer efficiency,which is
up to 8 5 %

Improved Reliability

3

·Caterpillar design 3 modules high ambient cooling package ensures machine continuous working in heavy duty applications
·Countershaft transmission with upgraded core components and modulation
improvement provides high reliability
