THEORY OF OPERATION
This work package describes the following functional systems: fuel system, air inlet and exhaust system, steering sys-
tem, brake system, electrical system, and mast hydraulic system.
This work package explains how the systems and components of the machine work together. A functional description is
provided for each major system and component.
The RTCH is an all-purpose, medium-sized, wheeled machine used for handling ISO containers. It is powered by a Cat-
erpillar V-8, direct-injected, intercooled diesel engine. Hydraulically operated implements allow for up, down, side shift,
and tilt positioning of the tophandler for ease of use during container handling operations. Articulated frame steering
provides maximum maneuverability.
General. Diesel fuel is drawn from the tank by a fuel pump, filtered by a primary fuel filter, routed to the fuel injection
pump and secondary filter, and then injected through the fuel injection nozzles into the engine cylinders. Air is drawn in
through dry-type, replaceable filter elements. A dust ejector removes incoming dust from the air and routes it out
Priming Pump. The priming pump is used to prime the fuel system on initial startup or after changing fuel filters. It
also removes air from the fuel system.
Ether Starting Aid. The ether starting aid delivers a measured amount of ether into the turbocharger outlet for ease in
cold weather starting. The ether is stored under pressure in a cylinder, and the amount to be sprayed into the outlet pipe
is controlled by an electrically activated valve.
