we have a design that can flip the bins from lid down to lid up, as well as any other direction needed.we can grab the bins in any positions.we can also stack very high, can limbo, all wheel drive( nice pushing force and rather fast), and can push stacks from the top of the ramp....
i would post pics here but u will have to go to twistedblizzard.com to see them...also there will be video soon
