ため、従来はシヤーシの構成部材を厚板鋼板によ

図つている。 It has been found that in aerial work vehicles, the maximum overturning moment occurs when the boom, which is pivotably mounted on the center of the chassis, is fully extended and as close to horizontal as possible. There is.
In order to prevent this overturning moment, a large counterweight is attached to the revolving frame serving as the boom support on the opposite side of the boom extension direction, that is, on the rear side.
In addition, in order to prevent the vehicle from falling over, it is effective to increase the weight of the chassis itself that supports the swivel mount to lower the center of gravity of the entire vehicle as much as possible. In order to make the chassis heavier, the chassis is manufactured using a thin steel plate, or by attaching weights to a thin steel plate.

るにはスペース的に困難を伴つている。 However, in the former type of thick steel plate, the cost is extremely high because the steel plate is expensive, and furthermore, due to differences in models (differences in ranks classified according to the overall length of the boom), the length of the chassis or The width must be changed to adjust the weight, making it impossible to standardize the chassis. On the other hand, the latter method of adding weights is not only expensive, but also has restrictions on the installation space for the weights, making it difficult to adjust the weight. In other words, the main body of a chassis is generally comprised of a pair of left and right side members that extend parallel to each other in the front-rear direction, but there is usually no hydraulic oil or gasoline between the two side members. Since each tank and related auxiliary equipment are arranged, the area that can be used as weight installation space is limited to the outside of the side member. However, since wheels are placed in front and behind this point, the weights must be installed within a range that does not interfere with the turning angle of the wheels and does not protrude from the width of the vehicle, so it is difficult to add the necessary weights. There are difficulties in terms of space.

される。 Both side members 12 include a hollow member 15 that is made of steel plate and has a hollow shape with a rectangular vertical cross section, thereby ensuring the strength necessary for the chassis 1, and a space 1 of this hollow member 15.
5a, and a heavy member 16 made of a filler such as high specific gravity concrete, waste molding sand, etc. The space 15a of each hollow member 15 has an appropriate number of partitions 17 in the longitudinal direction.
For example, as shown in the figure, it is divided into five small spaces, and these small spaces contain concrete as a heavy member 16 whose specific gravity has been increased as much as possible by mixing iron powder, etc., and waste material. The hole 1 formed in the upper plate of the hollow member 15 is filled with a filler such as foundry sand.
8, the chassis 1 is filled in a fluid state, thereby adding the necessary weight to the chassis 1 to prevent it from tipping over.

が可能である。 That is, in this embodiment, the side member 12 forming the main body of the chassis 1 is configured as described above, and therefore, for example, in the case of a model with a boom length of 12 m, three small spaces are filled with filler. In addition, in the case of a model with a boom length of 14 m, the volume of each small space and the specific gravity of the filler are adjusted so that by filling all five boxes with the filler, a predetermined weight corresponding to the boom length can be obtained. Once this is determined, the weight can be easily adjusted for each model. It should be noted that by adding more small spaces, it is possible to accommodate three or more types of models, but the amount of filling material for weight adjustment can be adjusted even if the partition 17 is omitted.

By adjusting the amount of filler, the weight of the chassis can be easily adjusted, and the chassis can be used in common for two or three types of models. Moreover, the strength of the hollow member itself is further strengthened by the filling material, and furthermore, the problems of installation space and wheel turning angle constraints, etc., which are found in conventional weight adding methods, are solved.
