At the same time, it is easy to wear and damage, the manufacturing process is complex, the material properties are required to be high, the installation difficulty is large, it is not convenient to disassemble, and the cost is high. The column lifting mechanism controls all columns to lift at the same time, which leads to all trolleys lifting at the same time and cannot act alone. At present, the gantry crane has a tire type and a track type. The tire type is not stable during movement and cannot meet the requirements of lifting semiconductor industry equipment. The track type needs to lay tracks, the track is long, occupies a large area, and is inconvenient to install and transport. The installation and disassembly method is not suitable for clean rooms.

[0010] Further, the two support columns at the bottom of the same main beam are fixedly connected by bolts.

[0011] Through the above technical scheme, the stability of the structure is improved.

[0012] Further, the walking track is segmented and connected by welding of square steel and H-shaped steel, and each segment after welding is connected by bolts to form a track.

[0013] Through the above technical scheme, the installation, disassembly and transportation are facilitated.

[0014] Further, the support column is composed of an upper column and a lower column connected by bolts.

[0015] Through the above technical scheme, compared with the traditional lifting column, the disassembly and installation are more convenient, and the structure is more stable.

[0016] Further, the motor track wheel adopts a three-in-one reduction motor, and the wheel part is a steel core nylon wheel.

[0017] Through the above technical scheme, the motor track wheel structure is more compact, works stably and has low noise, and the service life is improved.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:
