Abstract: A multiple-purpose utility vehicle has a working boom which is displaceably guided on a guide rail by a supporting carriage in the longitudinal direction of the vehicle. The guide rail is arranged at the side of the driver's cabin and integrated within the vehicle. The working boom is supported on the supporting carriage pivotably by more than 240.degree. so that a tool arranged at its end can be pivoted forward of the driver's cabin or backward of the driver's cabin. In all its positions the working tool is easy to be seen by the driver.

Abstract: A wheeled building and constructional machine of the mechanical shovel, bulldozer or the like type has an articulated steering system and comprises a vehicle chassis, a plurality of wheel axles, a hydraulic suspension system for the wheel axles, and at least one transversely stabilizing valve. The hydraulic suspension system comprises a plurality of fluid cylinders which are disposed between pivoting levers which are rotatably mounted and hold the wheel axles, and the vehicle chassis, and rotatably mounted on these vehicle parts. The fluid cylinders are adapted for action upon both of sides and are connected to the stabilizing valve or valves.

Abstract: The running gear of a construction vehicle or the like is provided with a resilient suspension adapted to be effective in transport operations and ineffective in working operations.
