[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a container gantry crane with an adjustable bracket, including a support frame 1. The support frame 1 is provided with a lifting bracket 2 above, and a plurality of groups of rollers 3 are provided on the lower end surface of the support frame 1. A plurality of through holes are opened on the support frame 1 between the rollers 3, and an engaging rod 4 is inserted through the through holes.

Thus, it is convenient to lift and limit the first fixing plate 7 through the engaging rod 4, and at the same time, the stability of the first fixing plate 7 during use is increased through the screw block 5.

[0020] A plurality of groups of support plates are respectively provided on the outer walls of the two vertical rods of the lifting bracket 2, and a first rotating rod 8 is inserted between the support plates.
