Abstract: A lifting device for moving two goods carrying platforms between different levels. The platforms are provided to perform a synchronous displacing movement in opposite directions relative to each other in one single path of travel. For the movement of the platforms transmission means are provided including two elongated flexible traction elements, preferably two chains. The one end of each element is fixed by anchoring to a stationary part of the lifting device and the other end is fixed to one of the platforms. A number of pulleys are provided to perform a linear reciprocating movement by means of driving means and thereby bring about a longitudinal change of a loop provided for each one of the traction elements and stretching around the respective pulley in opposite directions so that the loop which is connected with one of the platforms is lengthened, at the same time as the loop which is connected with the other platform is shortened and vice versa.

Abstract: A horizontally movable load transportation device is equipped with a vertically movable elevator. The elevator has a pivotally mounted conveyor device that is adapted to engage an edge of a load and transfer it toward a selected storage compartment. The storage compartments have movable load engaging devices which are adapted to engage another edge of the load to assist in the transfer of the load between the transportation device and the storage compartment.
