Abstract
A pivoting axle system for an aerial lift vehicle with a chassis includes a left axle supporting a left wheel and a right axle supporting a right wheel. The left and right axles are pivotable between a transport position and a working position. A first hydraulic cylinder is connected at one end to the chassis on a right side of a vehicle center line and at an opposite end to the left axle, and a second hydraulic cylinder is connected at one end to the chassis on a left side of the vehicle center line and at an opposite end to the right axle. In the working position, the first and second hydraulic cylinders are prevented from deflection beyond a yield point.
