[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a crane capable of lifting materials across a span, including a crane body 1, an upper rail 3 fixedly connected below a main beam 2 of the crane body 1, two ends of the upper rail 3 respectively close to rail-bearing beams 10 on both sides of the crane body 1, the lower part of the upper rail 3 is slidably connected to a lower rail 4 through two operating mechanisms, one operating mechanism is fixedly connected to one end of the upper rail 3, and the other operating mechanism is fixedly connected to the other end of the lower rail 4, and a hook structure 5 is slidably connected to the lower rail 4.

[0017] In this embodiment, the operating mechanism includes a left operating mechanism 11 and a right operating mechanism 12. The left operating mechanism 11 is installed on the upper track 3, and the right operating mechanism 12 is installed on the lower track 4. During the operation of the utility model, the operating mechanism drives the lower track 4 to move to the left, and the hook structure 5 is also connected to the lower track 4 through the operating mechanism. The hook structure 5 runs to the left on the lower track 4 until the hook structure 5 reaches the middle of the adjacent span to transport materials or hook up materials. After completion, it runs back to its original position in the opposite direction.

[0018] In order to limit the position, as an improvement of the technical solution, a limit baffle 6 is fixedly provided on the right side of the upper rail 3, an upper limit stopper 7 is fixedly provided in the middle section of the upper rail 3, and a lower limit stopper 8 is provided at one end of the lower rail 4 close to the limit baffle 6, and the sum of the heights of the upper limit stopper 7 and the lower limit stopper 8 is greater than the distance between the upper rail 3 and the lower rail 4.

[0019] When the lower track 4 moves to the right, the limit baffle 6 limits the extreme position of its right end. When the lower track 4 moves to the left, the lower limit block 8 moves to contact the upper limit block 7, limiting the extreme position of the left end of the lower track 4.

[0020] In order to support the end of the lower rail 4 away from the material during the process of lifting the material, as an improvement of the technical solution, a supporting reverse roller 9 is provided at the end of the lower rail 4 on one side of the running mechanism, and the supporting reverse roller 9 is in contact with the upper rail 3.
