ER OF A SIMPLE DESIGN

DYNAMICBRAKING EFFECT

T

he Closed Loop System features also a Dynamic BrakingEffect which automatically reduces the machine speed on sloops allowing the operator to keep a safe and precise machine control in all working condition. The Dynamic Braking can also be controlled on the move by the operator by acting on the decelerator pedal, thus decreasing the engine r.p.m. which means reducing pumps oil flow and consequently machine speed, same time achieving also great dozer precision work. Service brake is applied by a brake pedal. Parking brake, sprig applied and hydraulically released, becomes operative when lifting the two safety levers or, automatically, any time the machine is not moving for more than 30 seconds.

FINAL DRIVE REDUCTION

T

he power generated by hydraulic motors is transferredin a correct ratio to sprockets thanks to a sophisticated system which combines a triple reduction with a planetary reduction final drive.
