Claims

[Scope of Claim for Utility Model Registration] A posture maintaining member that always maintains a predetermined posture regardless of the vertical movement of the telescopic boom is attached to the tip of a telescopic boom that can be raised and lowered, and a lifting mechanism is attached to the posture maintaining member. An aerial work vehicle equipped with a bucket that can be raised and lowered, in particular, an upper link and both ends of the lifting mechanism that are pivotally connected at both ends to an upper bracket on the posture maintaining member side and an upper bracket on the bucket side so as to be able to rise and lower. A parallelogram link mechanism comprising a lower bracket on the posture maintaining member side and a lower link pivotably connected to the lower bracket on the bucket side, and an upper or lower link of the parallelogram link mechanism for maintaining the posture. In a hydraulic cylinder for raising and lowering a member, one of the upper link or the lower link in the lifting mechanism is constructed of a hollow cylinder, and the other of the upper link or the lower link is a hollow cylinder of the one link. The hydraulic cylinder is arranged so as to pass through the cylinder, and one end of the hydraulic cylinder is arranged between the hollow cylinder of the one link and an appropriate position on the posture maintaining member side or the bucket side, and the hydraulic cylinder raises and lowers the one link. An aerial work vehicle characterized by being configured to be driven.
