<p>The device (1) has a lifting unit i.e. rack feeder, that is movable along a linear stationary guiding way. A brake (5) is attached to an actuating unit (6) i.e. speed limiter, which automatically releases the brake for interception of the device during exceeding a preset speed. Another actuating unit i.e. clamping lever, attached to the brake is for manual releasing of the brake for fixing the device. The brake includes a clamping block (14), which clamps the device via a clamping jaw (15) at a vertically arranged guiding rail (4) in an operating case, where the brake acts on the rail.</p> |
