にした車両搭載クレーン。A base tube rotatably supported on the vehicle behind the driver's cab, a movable tube arranged to be movable up and down within the base tube, and a first boom whose base end is pivotally supported by the movable tube. , a second boom that pivotally connects the tip end of the first boom and the base end thereof and is folded and stored below the first boom in the retracted state; and a second boom that is disposed between the first boom and the movable cylinder. a first hoisting cylinder that controls the hoisting of the first boom by its telescoping motion, and a second hoisting cylinder that is disposed between the first boom and the second boom and controls the hoisting of the second boom by its telescoping motion; The movable cylinder is formed so that it takes a low position contracted into the base cylinder when traveling, and is connected and fixed to the base cylinder at a high position where it extends upward during crane work. The second boom is moved from the low position to the high position by regulating the expansion and contraction movement of the hoisting cylinder and extending the second hoisting cylinder while keeping a part of the second boom in constant contact with the vehicle side. Vehicle-mounted crane.
