A drum hoist including a movable drum which is arranged on a main shaft with a coupling apparatus for the releasable connection of the movable drum and the main shaft, a drum wheel which is connected fixedly to the movable drum so as to rotate with it, and a coupler wheel which can be displaced axially in an engagement direction and a disengagement direction with respect to the main shaft. In order to effectively prevent undesired disengagement of a coupler wheel of the coupling apparatus without mounting additional elements, coupling elements are arranged between the drum wheel and the coupler wheel which can be engaged and disengaged, which coupling elements can be brought into and out of engagement by a rotation of the engaged coupler wheel with respect to the drum wheel by the amount of the tooth flank play between the toothing systems of the two wheels.
