荷物昇降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. The load lifting vehicle is configured to raise and lower the guiding means by winding and letting out the rope by a winch, in particular, the length of the rope between the tip pulley and the guiding means changes due to the telescoping movement of a telescoping boom. In a cargo lifting vehicle in which the rope is suspended around a telescoping boom to prevent A rope length detection means is provided for detecting that the length of the guiding means reaches the lowest position of the telescopic boom due to descent, and the telescopic control device of the telescopic boom is controlled based on the detection result of this detection means. A telescoping boom retraction motion regulating device for a cargo lifting vehicle, characterized in that the telescoping boom is configured to disable the retraction drive of the telescoping boom.
