摘要:
Moving ramp intended e.g. for transportation of people, comprising plates (10) supported by wheels, which are guided for movement at an upper level to form the loaded part of the moving ramp, and at a lower level which is substantially parallel with the upper level, to form the returning part of the moving ramp, adjacent plates in each part being close to each other. Stationary guides (16, 17) are provided as upper and lower runway tracks for the wheeled plates. The plates at the edges thereof are pivotally connected to endless chains (14) at one end of the plates the chains extending along the parts to be driven in one direction in the upper part and in the opposite direction in the lower part, a sprocket wheel (15) being provided for each chain (14) at each end thereof defining the distance between the parts. The other end of the plates is free for angular adjustment. For lowering and raising, respectively, the plates by engagement with the end of the plates which can be freely adjusted angularly, a rotating element (20, 22) driven synchronously with the sprocket wheel is provided at each end of the moving ramp. A number of drive stations for the endless chains are distributed along the length of the chains at least in the upper part thereof.
