As shown in -268284, an elevating body is vertically movably mounted on a vehicle body, and a building material support member is vertically rotatable on a movable portion of a telescopic boom in a work vehicle in which an extensible boom is attached to the elevating body facing forward. Attached ones are known.

で使用する際の大きな課題となっている。The work vehicle of such a construction material transporting machine has a long overall length composed of a vehicle body, an elevating body and a telescopic boom, and has a large rigidity for supporting and transporting heavy building materials. Therefore, the weight of the entire work vehicle increases. In particular, when a counterweight is attached to the rear of the vehicle body to improve the stability of the vehicle body when transporting extremely heavy building materials, the weight of the entire work vehicle becomes very heavy.
For this reason, lifting and lowering the work vehicle requires an elevator with a large load capacity and a large space, so it may not be possible to move up and down with a simple elevator temporarily installed at the building construction site. This is a major challenge when using transporters at building construction sites.

る。Further, when a telescopic boom is attached to a vehicle body so as to protrude forward from the front of the vehicle body as in a working vehicle used as a conventional building material transporter, the distance between the telescopic boom and the rear of the vehicle body, that is, the total length, is reduced. For example, the turnability is poor, and it is not possible to enter a narrow passage such as a corridor of an apartment from a narrow entrance such as an entrance of an apartment, or to pass through a curve or a corner of a narrow passage. This is particularly noticeable when a counterweight is attached to the rear of the vehicle to improve vehicle stability when transporting very heavy building materials.
【０００６】また、車体安定性を向上するために車体に

持脚のために全長が長くなって小回り性が悪くなる。Further, when the front wheel support legs are attached to the vehicle body so as to face forward in order to improve the stability of the vehicle body, the front wheel support legs have a long overall length and poor turnability.
