[0018] Two running trolleys 2 are symmetrically arranged on both sides of the upper surface of the main beam, and each running trolley 2 is installed with a lifting and overturning device. The main beam 1 includes a middle crossbeam 101 and side crossbeams 102 symmetrically arranged on both sides of the middle crossbeam 101. Each running trolley 2 is installed across the middle crossbeam 101 and the corresponding side crossbeam 102, that is, a trolley track is arranged on the side crossbeam 102, and two trolley tracks are arranged side by side on the middle crossbeam 101. The running trolley 2 is installed with two trolley tracks for travel, one from the side crossbeam 102, and the other from the middle crossbeam 101.
