As shown in the figure, two uprights 2 are vertically welded to both ends of the beam 1 , the lower ends of the two uprights 2 are vertically welded and connected to a base 3 , and the base 3 is perpendicular to the length direction of the beam 1 . The beam 1 and the column 2 form the main frame of the hoisting device, and the base 3 can stably support the beam 1 and the column 2 to prevent the hoisting device from tipping over.

As shown in the figure, there are inclined support rods 4 on the outer sides of the two uprights 2 respectively, the upper ends of the two inclined support rods 4 are respectively welded and connected with the two ends of the beam 1, and the lower ends of the two inclined support rods 4 are welded with a support seat 5, and the support 5 The seat is parallel to the base 3 at the lower end of the two uprights 2 . The oblique support rod 4 and the support base 5 enhance the stability of the main frame, and when the hoisting equipment slides along the beam 1, the beam 1 and the column 2 are more stable.

As shown in the figure, the slide rail 6 and the slide frame 7 are hoisting parts. The slide rail 6 is parallel to the cross beam 1 , the slide rail 6 is located below the cross beam 1 , and the two ends of the slide rail 6 are connected to the two uprights 2 by welding. The sliding frame 7 is hung on the sliding rail 6, and the sliding frame 7 can slide along the sliding rail 6 to hoist the equipment.
