Front suspension arrangement (1) Cylinder mounting pin (2) Suspension cylinder (3) Front frame (4) Pivot pin cap for cradle (5) (5) Cradle (6) Axle case (7) Cylinder mounting pinThe front axle is mounted on a pivoting cradle assembly. Cradle (5) is bolted to axle case (6), and cradle (5) is attached to the main frame (3) by pivot pins (4) which are mounted in spherical bearings. This arrangement allows vertical movement of the axle. This arrangement does not allow vertical movement of one wheel relative to the other wheel. The cradle is a rigid assembly.Suspension cylinders (2) are mounted between cradle (5) and the main frame (3) by pins (1, 7). Suspension cylinders (2) are connected to a nitrogen charged accumulator. The accumulator acts as a spring.Rear Suspension Arrangement

Rear view (2) Rear frame (5) Rear axle (10) Panhard rodCenter axle (8) and rear axle (5) are mounted on suspension A-frames (6, 9), which are attached to rear frame (2) by pivot pins (1,7) .Pivot pins (6, 9) are mounted in spherical bearings in order to allow the axles to move vertically and pivot pins (6, 9) allow the suspension A-frames to tilt sideways. Each suspension A-frame is located laterally by a panhard rod (10) in order to prevent sideways movement.Suspension cylinders (3, 4) are mounted between the rear frame and the suspension A-frames. Suspension cylinders are connected by a closed hydraulic system. The suspension cylinders on each side of the machine are connected together in a separate closed circuit.If the center axle is deflected upward, oil from the front suspension cylinders is forced into the rear suspension cylinders and the rear axle moves down.If one side of the center axle is deflected upward, the center A-frame will be tilted and the oil from the suspension cylinder on that side of the axle will be forced into the corresponding rear suspension cylinder. This would cause that side of the rear A-frame to be deflected downward.Suspension Hydraulic System

The front system consists of suspension cylinders (1) and suspension accumulator (4). The right rear system consists of suspension cylinders (6) and the left rear system consists of suspension cylinders (10). The two rear systems are isolated by shutoff valves (5, 8) which are normally closed. These shutoff valves form a connection between the systems for servicing purposes only.All systems are initially filled with hydraulic oil by pump (13) through shutoff valve (2) and
