WHEEL CRANE

PURPOSE:To insure the sideway field of vision at running while bringing down a boom position by providing a cabin on a swing frame in the condition which the cabin is positioned in rear of the projecting part of a front fender onto a running frame and the bottom face is positioned lower than the upper face of the fender. CONSTITUTION:A cabin 8A is positioned in rear of the center part of a front fender 4 and the bottom face of the cabin is positioned lower than the upper face of the fender 4, namely, it is provided on a swing frame 7 rearward and downward compared with a customary cabin. By lowering a boom 10 downward, the center of gravity of a vehicle is positioned lower than the customary one. Consequently, by the fall of center of gravity of a vehicle, the width of the vehicle can be reduced than the customary one while keeping stable inclination fixed by law. A movable boom 12A on the lowest step is retreatingly moved than the customary one, and the base end part of the boom is positioned in rear of a boom pivot point. In this way, because the fitting point of a rod side end part against the boom 10A, namely the position of a bracket 16A is displaced rearward, the obliquely forward field of vision is improved than the past.
