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).
