Claims

[Scope of utility model registration request]

An arm that is attached to the vehicle so that it can be turned and raised freely, and is attached to the tip of the arm via a horizontal support shaft that is perpendicular to the arm's raising and lowering trajectory plane, and that always maintains a constant ground posture regardless of the raising and lowering movement of the arm. A posture maintaining member that pivots about the horizontal support shaft in relation to the up-and-down movement of an arm, and a bucket for riding a worker attached to the posture maintaining member. In particular, an article lifting device comprising a jib attached to the posture maintaining member so as to be horizontally rotatable, a hook suspended from the tip of the jib via a rope, and a winch for winding and unwinding the rope. , the attitude maintaining member has a through hole penetrating in the vertical direction, and the winch is disposed on the attitude maintaining member or the bucket and is pulled out from there, passing the rope through the through hole from below and moving the rope upward. The jib is bent into a substantially L-shape, consisting of a rising part whose lower end can be rotatably fitted into the through hole, and a rocking arm part that continues to the upper end of this rising part. A jib body made of steel pipe and having a U-shaped groove extending in the longitudinal direction on the back surface of the rising portion, an intermediate pulley provided on the back surface of the upper end of the rising portion of the jib body, and a rocking arm of the jib body. When the lower end of the rising portion of the jib is rotatably fitted into the through-hole of the attitude maintaining member, the rope pulled upward from the through-hole is connected to the U-shape. 1. An article lifting device for an aerial work vehicle, characterized in that the device is configured to move through the mold groove, the intermediate pulley, and the tip pulley in this order.
