ARTICULATED DOZER WITH SUSPENSION AND SUSPENSION LOCKOUT

An articulated loader has an articulated chassis and two A-frames. The points of the A-frames face each other. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chas...

Zusammenfassung:	An articulated loader has an articulated chassis and two A-frames. The points of the A-frames face each other. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chassis at points close to but offset from the point of vehicle articulation via ball joints and via hydraulic suspension cylinders toward the wider portions of the "A"s. The vehicle is propelled along the ground by tracks that are independently suspended. The invention includes a suspension lockout feature to, effectively lockout the suspension system, i.e., render it rigid. One or more valves may are used to prevent hydraulic flow from and two the hydraulic suspension cylinders.
