THEORY OF OPERATION - CONTINUED
HYDRAULIC SYSTEM - CONTINUED
Steering System. The steering system is a variable flow modulated system. This type of system allows the operator
good control for minor steering corrections at fast ground speeds as well as good control while operating at slower
speeds during tight turns.
Scraper Hydraulic System. The scraper hydraulic system consists of three primary hydraulic circuits to support
scraper operations: bowl circuit for raising and lowering the bowl; ejector/floor circuit for ejecting material from the
bowl; and elevator circuit for loading and unloading material.
