Engine/Power Train Integration Electronically combined power train components optimize performance. Service Brake Sensor Engine Sensor ARC ARC Switch Service Brakes Secondary Brakes Axle Speed Sensor TCS Position Sensor Steering Cylinder Downshift Inhibitor Reduces your operating costs by electronically integrating the 797’s machine computer systems. This optimizes overall power train performance while increasing reliability and component life. Prevents engine overspeeding by keeping the transmission from downshifting until engine speed reaches the downshift point. Controlled Throttle Shifting...

Cat Braking System Superior braking control lets your operators focus on productivity. Integrated Braking System Long Life The Cat, oil-cooled braking system delivers you reliable performance and control in extreme haul road conditions. The integrated system combines the service, secondary, parking brakes and retarding functions in the same system for optimum braking efficiency that does not burn fuel while retarding. An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Oil-Cooled...
