形法で製作すると、どうしても曲がりが生じる。(Prior Art and its Problems) The elevating and descending kina range guide columns in conventional traveling cranes have been manufactured by bending, welding, and machining steel plates. In recent years, in order to reduce weight, eliminate welding points, reduce manufacturing costs, and further increase design value, it has been considered to use an integrally extruded material such as aluminum for the elevating kina range guide column. However, when a long object such as the above-mentioned elevating range guide column is manufactured by extrusion molding, bending inevitably occurs.

来るのである。(Operations and Effects of the Invention) According to the elevating carriage and nozzle guide device of the present invention that can be implemented as described above, the pair of front and rear supports that guide the elevating carriage are made of an integrally extruded product of aluminum or the like. Therefore, the advantages of reducing the weight of the crane, reducing costs due to the elimination of welding points, and improving the design effect can be obtained.In particular, the above-mentioned support has a symmetrical cross-sectional shape with guide rails on both the front and rear sides. Therefore, even if a bend occurs in the support due to extrusion molding, the top, bottom, left, and right sides of the support 13 and 14 are selected and installed so that the bending direction will be in the same direction as shown in Figure 6. By this, the distance Lm between the heightwise intermediate portions of both columns 13 and 14
can be made substantially equal to the specified interval Le between the upper and lower ends, and the elevating carriage can be raised and lowered safely and smoothly.
