A lifting mechanism device having an electric or pneumatic motor and two link members has two chain wheels, which are arranged beside each other on a shaft, which is driven by the motor, wherein each chain wheel is used to guide in each case a portion of a link chain with alternately horizontal links and vertical links, that is to say, having pockets for receiving horizontal links and having a groove which extends in the circumferential direction for receiving vertical links. The chain wheels are arranged in a rotationally secure manner with respect to each other in an angular position in the same direction in which the angle pockets of the two chain wheels are located offset with respect to each other by only a distance parallel with the shaft, but are not rotated with respect to each other.
