To prevent a random coil of and an overwind of a belt with simple structure, a belt hoist includes a random coil preventing member pressed against the belt wound around a winding member to prevent a random coil of the belt, the random coil preventing member being movable in response to changes in circle diameter of the belt; and control means for controlling drive of drive means in association with the random coil preventing member when the circle diameter becomes a specified diameter. Further, a belt guide having a belt guide portion is supported between two side plates in such a freely sliding manner as to allow the winding of the belt onto the winding member.
