A drum rotation machine includes a working drum mounted for rotation within an enclosure. An access door provides access to the interior of the enclosure, and the access door is moveable between a closed position and an open position. A latch assembly is mounted on the enclosure and is moveable between a locked position and an unlocked position. In the locked position, the latch assembly prevents the access door from moving from the closed position to the open position. In the unlocked position, the latch assembly allows the access door to be moved from the closed position to the open position, and engages an anti-rotation catch on the working drum to prevent rotation of the working drum.
