ABSTRACT:
A rotary device adapted for use with fork-lift trucks, wherein the fork members thereof are mounted to the rotary device and arranged in a normal pick-up position so as to engage a conventional trash container, whereby the container is lifted and rotated about the axis of the device, thereby dumping the trash disposed in the container. The rotary device comprises a rear mounting plate adapted to be secured to the lifting structure of the fork-lift. The plate includes a bearing spindle attached thereto on which a bearing hub is rotatably mounted; and the bearing hub includes a locking drum which is releasably positioned by a locking assembly mounted to one side thereof. Secured to the free end of the bearing hub is a fork-mounting plate whereby the fork members are adapted to be supported thereon, so as to rotate with the bearing hub. When the locking assembly is released, the container will automatically rotate for dumping; and, when the forks are lowered, the container may be easily returned to the normal upright position.
