業車の安全装置。[Scope of Claim for Utility Model Registration] A swing arm is provided at the tip of a telescoping boom that is mounted on a vehicle so that it can swing freely horizontally, and
A safety device for an aerial work vehicle comprising a bucket for boarding a worker, which is attached to the tip of the swing arm so that its outside position can be rotated horizontally; A safety device configured to monitor the relationship between the lifting angle and the limit value calculated as a function of the length of the telescopic boom, and to restrict the lowering and extension movements of the telescopic boom when the actual value reaches the limit value. an arm position detection means for detecting whether the pointing direction of the arm is in the left region or the right region of a straight line passing through the rotation center of the arm and along the axis of the boom in a plan view; When viewed, the pointing direction of the bucket is
A bucket position detecting means is provided for detecting whether the bucket is in a left region or a right region of a straight line passing through the center of rotation of the bucket and along the axis of the boom, and when the actual value reaches a limit value, the arm position is detected. When the detection means detects the left area, the right turning movement of the arm is restricted, and when the arm position detection means detects the right area, the left turning movement of the arm is restricted, and the bucket stop When the position detecting means detects the left area, the right turning movement of the bucket cart is restricted, and when the bucket cart position detecting means detects the right area, the left turning movement of the bucket cart is restricted. A safety device for aerial work vehicles that is characterized by:
