Power Control

Rugged drive shaft transmits the huge torque C175-20 on the rear axle-mounted seven-speed transmission, which transmits power smoothly to the double step-down final drives through a massive rear axle. Torque converter with integrated locking increases speed characteristics and fuel efficiency.
Electronic control of the clutch pressure Caterpillar effectively controls the clutch when changing speed and load. This provides a gear without power loss. Additionally provides smooth shifting and increasing the lifetime of the coupling. Separate fluid system ensures supply of clean cold oil for lubrication and clutch transmission. Transmission provides protection against over-speeding of the engine and prevents downshifting (at high speeds) and allows you to program the maximum speed.
Integrated Braking System Caterpillar 797F model combines the functions of three braking systems (primary, secondary and parking) with auto deceleration device with hydraulic drive. Deceleration device placed in separate blocks located at each wheel. These submersible multi blocks have a common oil-cooled braking / retarding surface at 330,645 square centimeters. Integrated heat exchanger controls brake oil temperature, which ensures the brakes without derating and longer brake life.
Frame and Body

The frame consists of nine cast elements of mild steel welding are performed using the robot. All items have been tested with ultrasound. Large radial cast parts are elastic, allowing the frame to absorb bending and ensures its durability. Low-carbon steel provides the required flexibility, durability and impact resistance, even in cold climates.

For Cat 797F dump truck are four types of bodies intended for mining, which can be used in conjunction with variable lining systems, which provides an optimal balance between total usable volume and strength for a particular application. Customers can customize their body to the requirements of production and operating constraints. In some cases, the total effective volume can be 20 tons more than for the model 797B.
