車の伸縮ブーム縮小動規制装置。[Scope of claim for utility model registration] A telescoping boom whose base end is pivotably mounted on a swivel platform mounted on a vehicle, and which is guided between the base end and the tip of the telescoping boom along the telescoping boom. A cargo lifting vehicle in which a lifting bucket is attached so as to be freely raised and lowered via a guide means, and in particular, a rope from a winch attached to the proximal end of a telescoping boom is connected to the guide means via a pulley at the end of the telescoping boom. In the cargo elevator, the guide means is raised and lowered by winding and letting out the rope by a winch, wherein the guide means is attached between the base end of the telescopic boom at a proper position and the guide means at a proper position, and the guide means is attached to the telescopic boom. A detector is installed to detect when the guide means has descended to a position near the proximal end of the telescopic boom, and the detection result of this detector is used to control the telescopic boom's telescopic control device. A telescoping boom retraction motion regulating device for a cargo lifting vehicle, characterized in that the device is configured such that the movement of the telescopic boom is disabled.
