ABSTRACT:
In a portable unit having a generally horizontal frame, a container normally resting on the frame and pivotally connected at its rear of the frame for tilting upwardly and rearwardly toward a dumped position, the container having a door at its rear for loading and unloading material for opening when the container is in a dumped position, the improvement being a lift-and-tilt mechanism including a linkage pivotally connected at one end to the frame, and with a subframe unit interposed between the container and unit frame to support the container, with an inner end of the subframe unit pivotally connected to the linkage unit at an opposite end, whereby the linkage and subframe units are movable from a nested position substantially flat with the unit frame to a raised position with the linkage unit disposed substantially vertical, and with the subframe unit holding the container in a normally horizontal position, and with the container tiltable to its dumped position; and a power-operated unit for moving the linkage unit from its nested position to its raised position; a lift arm unit connected between the linkage unit and the subframe unit and engaged with the underside of the container for automatically tilting the container toward a dumped position upon raising of the linkage and subframe units; and a strap unit interconnected between the container door and the linkage unit for automatically pivotally opening the door upon the container being tilted upwardly and rearwardly to its dumped position.
