Document Type and Number:
Japanese Patent JP3964715
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high altitude working vehicle with superior safety capable of effectively using a lifter in high altitude work by a bendable boom without complicating a structure, and contributing to speeding up of rescue activity requiring urgency.
SOLUTION: The high altitude working vehicle is provided with a lifter 51 supported so as to move in a boom longitudinal direction by a telescopic boom 3 composed of a plurality of unit booms, and a bending mechanism 81 bending the uppermost unit boom 3e around a bending shaft 80 parallel to a horizontal direction of the boom 3. In a portion supported by the uppermost unit boom 3e in the lifter 51, relative movement toward a front portion 3e' of a bending position is prevented with respect to the uppermost unit boom 3e when the uppermost unit boom 3e is bent, and relative movement in a rear portion 3e" and the front portion 3e' of the bending position is allowed with respect to the uppermost unit boom 3e when the uppermost unit boom 3e is not bent.
