Claims (1)

[Scope of Claim for Utility Model Registration] An operating device for a two-bucket type aerial work vehicle, which comprises two buckets for a worker to board on the tip of a retractable boom that is attached to the vehicle so that it can be rotated and raised freely, In particular, a drive unit that drives the telescopic boom to raise, rotate, and extend and retract, an operation means that is arranged on each bucket and sends a control signal to the drive unit, and a control signal from each of these operation means is selected to perform one of the operations. A switching means for transmitting a control signal to the drive unit, and a selection means arranged on each bucket so that the switching means can be selectively operated and controlled from each bucket, and the telescopic boom is driven from one bucket. At the same time, the switching means is switched by the selection means on one bucket side so that the control signal of the operating means on the bucket side is transmitted to the drive unit to drive the telescopic boom, and at the same time, the telescopic boom is driven from the other bucket side. Operation of a double-bucket type aerial work vehicle configured to sometimes switch the switching means by the selection means on the other bucket side and transmit the control signal of the operating means on the bucket side to the drive unit to drive the telescopic boom. In the apparatus, a first operation detection means for detecting that the operating means disposed on one bucket side is being operated, and a second operation detecting that the operating means disposed on the other bucket side is being operated. When the first operation detection means detects that the operating means disposed on one of the buckets is driving the telescopic boom, the selection means disposed on the other bucket The telescopic boom is driven by a first selection inhibiting means that operates upon receiving a signal from the first operation detecting means so that the switching means cannot be switched, and an operating means arranged on the other bucket side of the second operation detecting means. A second switch is provided to prevent the switching means from being switched by the selection means disposed on one of the buckets when it is detected that the switching means is switched on.
An operating device for a two-bucket type aerial work vehicle, characterized in that second selection inhibiting means are respectively arranged to operate in response to a signal from an operation detecting means.
