Abstract: The present invention relates to a stacking machine, which comprises a base, a body movably arranged on the base, and a translational mechanism for driving the body to make a translational motion on the base. The synchronous belt used in the present invention can effectively resolve the problem of slipping caused by wheel rolling, and thus enables the movement of the stacking machine to be more accurate, with the highest speed of the movement also increased significantly. Besides that, the synchronous belt mechanism is more accurate in positioning, which reduces the number of times of repeated adjustments and maintenance caused by bigger positioning errors.

Abstract: The present invention discloses a crane and an automated storage and retrieval system. The crane includes a first arm, a second arm, a first vertical transmission mechanism and a second vertical transmission mechanism. The first vertical transmission mechanism transmits the first arm and the second arm to move vertically in a synchronous manner, and the second vertical transmission mechanism transmits the second arm to move vertically with respect to the first arm. As such, the present invention can increase the moving volume of a single turn of movement as well as improve the moving efficiency and production efficiency.
