Abstract: A guided working device (1) is driven by an operable traction motor (2) for movement along a travel rail (3). The working device carries a driver (4) provided with articulated heads for a measuring carriage (5), which measuring carriage always travels the same distance as the working device (1). The measuring carriage travels on a control rail (11) and includes a measuring device (6). A plurality of sliding conductors (17) are also receivable by the control rail (11). The measuring carriage carries a preferably toothed measuring wheel about at least a circumferential portion of which a preferably toothed measuring belt is wrapped. The measuring wheel (7) is pressed, by guided wheels (8) in front of and behind the measuring wheel, against a toothed belt supporting surface which is associated with the control rail (11).

Abstract: A displacement armature motor is formed such that the deformation element allows a larger axial shifting and displacement path of the displacement armature while requiring a lower construction precision. The deformation element includes two frames (17, 17a). The frame (17a) is connected via two of its corner attachment positions (17b) to an attachment plate (19). The attachment plate (19) is connected to an extension (31) of the displacement armature. The frame (17) is connected with two of its attachment positions to the carrier arms (15a) of the support ring (15). The two frames (17, 17a) are connected to each other with their respective remaining corner attachment positions (17c) via a transfer element (18).

Abstract: A crane wheel is adjustably mounted in the web structure of a crane carriage, head carrier, or the like by a bearing holders on each side of the wheel. The bearing holders are individually, pivotably fixed to the web structure by aligned clamping sleeves above axle. Two pendulum-type bearings in the necks of the holders journal the wheel axle. Adjusting screws mounted on the carriage abut cam stops on the bearing holders to adjustably fix the orientation of the wheel axles, including the plane of rotation of the wheel.
