装置。(1) Safety of an aerial work vehicle equipped with a boom mounted on a vehicle so that it can be adjusted to raise and lower and rotate freely, a packet or sub-boom that is rotatably installed at the tip of the boom, and a drive device that drives the packet or sub-boom to rotate. The device includes a limit switch that operates when the lodging direction moment acting on the boom reaches a limit value, a left area detection switch that detects and operates when the packet or sub-boom is on the left side of the boom, and the packet or sub-boom. A right area detection switch is provided that detects and operates when the sub-boom is on the right side of the boom, and when the limit switch and the left area detection switch are both activated, the packet or the sub-boom is disabled from turning right, and the limit switch the limit switch so as to disable left rotational movement of the packet or sub-boom when the right area detection switch is activated together;
A pot metal device for an aerial work vehicle, characterized in that a left area detection switch, a layer area detection punch, and the drive device are associated.
