  • Publication number: 20230042516
    Abstract: A stack lifting assembly for incrementally lifting stacks of flats loaded typically with produce to an unloading device and system. The assembly is configured to receive stacks of flats full of produce such as berries, and to lift the stacks to an unloader. The stack of flats is lifted allowing for the top flat to be removed and dumped, with the remaining stack of flats lifted and the process repeated. The stack lifting assembly has a frame, with two counter rotating belts that have flat support tabs that engage the bottom flat in a stack of flats, and lift the entire stack of flats. The dumping operation is allowed to proceed continuously, with no pauses to load stacks of flats. Throughput and safety are greatly improved.
