PROBLEM TO BE SOLVED: To provide a cargo transporting machine using air for a driving source to elevate up and down cargoes via a belt, wherein the elevating speed of the belt during sudden elevation is restricted. SOLUTION: In a cargo transporting machine using air for a driving source to elevate up and down cargoes via a belt, when the belt 6 is elevated up at a property desired speed or higher, the elevating speed of the belt 6 as a result of a hook 13 arranged in a rotor 12 rotated following the belt 6 being projected with centrifugal force is restricted by braking the belt 6.
