Abstract

1. Device for lifting and lowering lifting platforms under the control of a pressure medium, comprising two valves (2, 3) being arranged in a valve housing unit (1) and capable of manual operation by pushbuttons (4, 5), one valve (2) of which is inserted as an air admission valve in a line between the pressure medium supply (housing connection 6) and the lifting device (housing connection 6') for the lifting platform, while the other valve (3) is inserted as an air exhaust valve in a line between the lifting device (housing connection 6') and atmosphere (port 25'), wherein the line between the pressure medium supply (housing connection 6) and the lifting device (housing connection 6') incorporates a check valve (31 to 33) and wherein a cylinder lock (lock 39, cylinder part 40) engages a housing hole (housing recess 37) for the purpose of locking or releasing (4, 5) the pushbuttons (4, 5), a front part (locking member 36) of the lock (39, 40) being located at the locking position beneath bottom sections (bottom sides 18 and 29) of both pushbuttons (4, 5) and at the release position outside the stroke of both pushbuttons (4 and 5).
