AI Technical Summary
Existing gantry cranes are difficult to adjust in height and are cumbersome to disassemble and reassemble, especially in narrow work areas.
A support box with different pitch mounting bolt holes at its upper and lower parts, along with an L-shaped plate for pressing and fixing the H-shaped steel, allows for the connection of H-shaped steel and pipe supports with different pitch widths, enabling adjustable height and easy disassembly of the gantry crane.
The solution allows for easy adjustment and disassembly of the gantry crane, enabling it to be assembled in narrow spaces, facilitating efficient use in construction sites.

Summary of the Invention
Problems to be Solved by the Invention
[0004] It is difficult to adjust the height of a gantry crane, and because it is large, it has been difficult to carry it into a narrow work area. An object of the present invention is to enable easy adjustment of the height of a gantry crane and to enable disassembling and assembling the gantry crane in a narrow work area.
Means for Solving the Problems
[0005] By using a ready-made pipe support for the column part of the gantry crane, the height can be adjusted. In that case, since the H-shaped steel of the crane and the pipe support have different pitch widths, they cannot be simply connected with bolts. In order to connect members with different pitch widths, a support box was devised. The pitch of the mounting bolt holes provided in the upper part and the lower part of the support box is different. In the upper part of the support box, an L-shaped plate for pressing and fixing the H-shaped steel is provided.
Effects of the Invention
[0006] Using the support box of the present invention, a gantry crane can be easily fabricated by connecting the H-shaped steel of the crane and the pipe support, and the height can be adjusted. Furthermore, this gantry crane can be easily disassembled, and the parts such as the H-shaped steel and the pipe support of the crane after disassembly can be carried by hand, and the gantry crane can be assembled in a narrow place.

Modes for Carrying Out the Invention
[0008] Hereinafter, description will be made with reference to the drawings.
Examples
[0009] As shown in FIG. 1, a pipe support is used for the column portion of the crane. The H-shaped steel of the crane and the pipe support are connected using the support box of the present invention. Thereby, it becomes possible to easily adjust the height of the gantry crane. FIG. 2 shows details of a state in which the pipe support and the H-shaped steel are connected using the support box of the present invention. Here, mounting bolt holes with different pitches are provided at the upper and lower parts of the support box, and at the upper part of the support box, an L-shaped plate for pressing and fixing the H-shaped steel and bolt holes for tightening the plate are provided.
Industrial Applicability
[0010] It is a support box that can easily adjust the height of a gantry crane by using a pipe support for the column portion of the crane, and facilitates the disassembly and assembly of the gantry crane. It can be expected to be utilized at many construction sites.
