THEORY OF OPERATION
The D6K Dozer consists of the following functional systems: engine, powertrain, brake, electrical, and hydraulic.
This work package explains how the systems and components of the machine work together. A functional descrip-
tion is provided for each major component and system.
The D6K Dozer is an all-purpose, medium-sized, self-propelled, full-tracked crawler used for cutting, moving, and
dozing various types of granular material (dirt, stone, sand, etc.). Power is provided by a Caterpillar in-line, six-cyl-
inder, direct injected, diesel engine. Hydraulically operated implements allow blade positioning for dozing material
and snow removal in a forward direction. A hydraulically operated ripper allows loosening of compacted material.
The machine has a sound-suppressing Rollover Protective Structure (ROPS) cab with insulation, heater, air condi-
tioning, and windows, which allow for all-weather operation.
