Claims

[Claims for Utility Model Registration] (1) At least one bucket is held in equilibrium at the tip of a boom that can be raised, rotated, and extended, and is pivotally supported on the tip of the boom so that it can swing freely in the vertical direction. a balance member that is maintained in balance; a biasing arm having its base end attached to the balance member; a first arm having its base end pivotally supported at the distal end of the biasing arm so as to be swingable in a horizontal direction; and the first arm. a second arm whose base end is pivotably supported horizontally at the distal end thereof; and the bucket which is pivotably supported horizontally at the distal end of the second arm. The base end of the biasing arm is pivotally supported by the balance member so as to be able to swing in the horizontal direction, and when the biasing arm is pivoted in the width direction of the boom, the tip pivot portion of the biasing arm is pivoted to the boom tip or the boom. An aerial work vehicle characterized by being located outside the maximum width part of either of the above. (2) When the biasing arm is swung forward, the tip of the first arm protrudes to the opposite side of the boom so that it can be swung rearward.
The listed aerial work vehicle. (3) at least one bucket is held in balance at the tip of a boom that can be raised, rotated, and extended, and a balance member is supported in balance by being pivotally supported on the tip of the boom so as to be swingable in the vertical direction; a biasing arm whose base end is attached to the balance member; a first arm whose base end is pivotally supported to the distal end of the biasing arm so as to be swingable in a horizontal direction; In the aerial work vehicle, the aerial work vehicle is provided with a second arm pivotally supported to be swingably supported at the base end of the biasing arm, and the bucket belt pivotally supported horizontally to the distal end of the second arm. is fixed to the balance member, and the tip pivot portion of the biasing arm is located outside the maximum width of either the boom tip or the boom. (4) Claim 1, characterized in that the bucket can be raised and lowered with respect to the second arm or the balance member.
Or the aerial work vehicle described in 2 or 3.
