摘要： PROBLEM TO BE SOLVED: To move a boom tip part in many variations with simple operation. SOLUTION: When a mode changeover switch 26 is set in horizontally moving mode and a derricking/telescopic operation lever 21 is operated, the controller 27 controls boom motion based on information detected by detectors 23, 24, so that a workbench moves horizontally, linearly longitudinally along a horizontal line H at the present height of the workbench. At this time, simultaneously, operation of a turning operation lever 22 enables the boom to turn. By moving the workbench horizontally, linearly longitudinally through operation of the derricking/telescopic operation lever 21, and simultaneously by operating the boom to turn with the turning operation lever 22, carved movement of the workbench can be done.

摘要： 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

摘要： PROBLEM TO BE SOLVED: To perform overturning preventive control by detecting the attitude and contracted state of a post. SOLUTION: A turning, derricking and telescopic boom 4 is disposed on a vehicle, and the vertically extensible post 12 supported to a supporting arm 6 is disposed at the tip of the boom 4. A workbench 18 is disposed at the tip of the post 12, and the post 12 is provided with a post derricking motion sensor 13 to detect the angle of the post 12. A post extension sensor 14 is provided at the lower part of a telescopic cylinder 11d of the post 12 to detect the contracted state of the telescopic cylinder 11. A control device 50 allows the telescopic cylinders 11a-11d to be extensible when the post 12 detected by the post derricking motion sensor 13 is positioned at a prescribed angle including a vertical line to the ground surface. The control device 50 allows the derricking motion of the supporting arm 6 when the post 12 detected by the post extension sensor 14 is contracted to a prescribed length or less including the totally contracted state. This constitution can positively prevent the abrupt change of overturning moment caused by the change of a center-of-gravity position, and overturning of the vehicle for high lift work can be prevented.
