PROBLEM TO BE SOLVED: To provide a boom working vehicle with a working bench to be kept in horizontal and correctly and safely stored in a vehicle body at its storage position even when the vehicle is set on a slope. SOLUTION: In the boom working vehicle, when the working bench is located apart from the storage position, a levelling device 70 performs levelling control using a detection value detected by a working bench absolute oscillating angle detector 63 and so the working bench is kept always in horizontal. When the working bench is located in a predetermined range near the storage position, the levelling device 70 performs such levelling control that the inclination of the working bench to the vehicle body is eliminated by using a detection value detected by a working bench relative oscillating angle detector 61. Thus, the boom working vehicle is provided with the working bench to be correctly and safely stored in the vehicle body at its storage position. COPYRIGHT: (C)2003,JPO
