PROBLEM TO BE SOLVED: To provide a wheel crane vehicle body frame capable of strengthening the vehicle body frame and increasing the durability of an entire device by suppressing a vehicle height while maintaining an engine for work machine driving, or the like.SOLUTION: This wheel crane vehicle body frame has: an intermediate frame part 2A on which an upper turning body 3 is mounted; and a front frame part 2B and a rear frame part 2C that form a rectangular parallelepiped frame body 100 with the intermediate frame part 2A and respectively extend to one side and the other side of the intermediate frame part 2A. The rear frame part 2C has an upper surface partially opened so as to attach a power unit box-shaped in section and used for driving a device. Both left and right side plates 11 and 11 of the rear frame part 2C positioned in an area behind a partition wall (partition wall) 110A installed between the rear frame part 2C and the intermediate frame part 2A are set so as to be upward-tapered in a reverse-truncated shape from a lower side to an upper side.SELECTED DRAWING: Figure 1

    【課題】作業機駆動用のエンジン等を保持しつつ車高を抑制し且つ車体フレームの強化と装置全体の耐久性増大を図ったホイールクレーンの車体フレームを提供すること。【解決手段】上部旋回体3を搭載する中間フレーム部2Aと、この中間フレーム部2Aの一方の側と他方の側にそれぞれ延設され前記中間フレーム部2Aと共に直方体状のフレーム本体100を形成する前方フレーム部2Bおよび後方フレーム部2Cとを有する。後方フレーム部2Cを、断面箱型で且つ当該装置駆動用のパワーユニットを装備可能に上面が一部開放された構成とする。又、この後方フレーム部2Cと前記中間フレーム部2Aとの間に設置された隔壁(仕切り用隔壁)110Aより後方の領域に位置する前記後方フレーム部2Cの左右両側面板11,11部分を、下方から上方に向けて断面逆ハの字状の上広がり状態に設定したこと。【選択図】図1
