Abstract: A bent-axis machine comprises a housing having a control cover and a piston drum which is rotatably mounted in the housing on a valve plate and which has axial cylinders, each of which receives a piston. An adjustment system includes a pivot cradle via which the piston drum and the valve plate can be pivoted relative to the drive axis about a maximum working range which is delimited by a minimum pivot angle and a maximum pivot angle. The minimum pivot angle of the working range is shifted out of its zero position by at least 5°, and the maximum pivot angle is extended in the same way by at least 5° in order to retain the entire working range about the region left out of the lower region.

Abstract: The operating pressure for the hydraulic drive means (15; 26) is generated in the chassis (2) of the vehicle (1). A revolving structure (3) is arranged on the chassis, said revolving structure carrying the driver's cabin (7), a boom (5) with a tools (6) and a hydraulic motor for rotation of the revolving structure (3) relative to the chassis. The revolving structure is connected to the chassis by a live ring (16;23) that is driven by said hydraulic motor and has a hydraulic fluid duct (12;24) between the chassis and the revolving structure. The chassis is provided with an eccentric plate (11) carrying on its top side the above-mentioned live ring for the revolving structure while the bottom side of said eccentric plate has an eccentrically supported displacement bearing (13). Said displacement bearing is secured by a latching device (25) on the bottom side of the eccentric plate (11) during normal operation of the vehicle or digger (1).

Abstract: A loader is described, having a support frame (1) supported on front and rear wheels (2, 3) and receiving a driver cabin (4), to which a front boom (5) is linked on the rear side of the driver cabin (4), having two spars (6) running on both sides of the driver cabin (4), which form a curved section (10) overlapping the particular front wheel (2), and having a pivot drive (7) engaging on the lateral spars (6) for raising and lowering the front boom (5). In order to provide advantageous construction ratios, it is suggested that the spars (6) have a lengthwise section (9), engaging between the front and rear wheels (2, 3) in the lowered setting of the front boom (5) and running below a lateral cabin entrance, to which the curved section (10) overlapping the particular front wheel (2) is attached.
