Brakes

The brakes are not hydraulic, but rather use a Caterpillar C18 ACERT turbocharged aftercooled diesel 6-cylinder 24-valve liquid-cooled engine brake. The engine brake is a compression release brake that works by restricting the flow of air out of the engine, which creates resistance and slows the vehicle down. The engine brake is activated by a switch on the dashboard. The brakes are also equipped with an anti-lock braking system (ABS) to prevent the wheels from locking up during hard braking. The ABS system uses sensors to monitor the speed of each wheel and adjusts the braking pressure accordingly.

Steering

The steering is an articulated power steering system that is controlled by a Caterpillar 18.1L 6-cylinder diesel engine. The steering system is designed to provide precise control and maneuverability, even in tight spaces. The steering wheel is adjustable for height and tilt, and the cab is equipped with air conditioning to keep the operator comfortable during long hours of operation. The fuel tank has a capacity of 390 gallons / 1476.2L.
