Claims

[Scope of Claim for Utility Model Registration] (1) Mounting brackets or leaf springs that protrude in front of the bumper that are attached to the front part of the truck body at a predetermined interval on the left and right sides, and a plate spring that is attached between the mounting brackets and located in the middle part of the bumper. An elastic member that is stretched by the hoisting of a hooked crane hook, or a steel cable that is attached between the plate springs so that the plate spring is bent when the crane hook is hoisted, and a steel cable that is attached to the tip of the crane boom and is stretched by the hoisting of the crane hook. A hook retracted state when the elastic member is extended to a predetermined length or a hook retracted state when the leaf spring is bent by a predetermined amount is detected at the sheave block end of the crane hook, and a hoisting stop signal is sent to the crane operator. A crane hook securing device for a crane loading truck, which is equipped with a limit switch for detecting the storage of the hook. (2) The limit switch has a weight that is suspended from the switch body by a string and is movable using the crane hook's suspension wire as a guide, and when the elastic member is extended to a predetermined length by hoisting the crane hook or when the elastic member is When the weight is bent by a predetermined amount, the weight is pushed up by the end contact of the sheave block, the weight hanging string is loosened, and the switch is turned on, thereby issuing a hoisting stop signal to the crane operator. A crane hook securing device for a crane loading truck as set forth in claim 1 of the utility model registration claim.
