is it overweight? Also can you rotate the boxes when you pick them up?
It all and all looks like a very sturdy frame, Al or steel? It almost looks like it could be steel but that would be way way too heavy. Also, I know you are probably not made to be a pushing robot but what about traction? Those wheelchair wheels are not good on that stuff at the top of the ramp.
Also, could you tell us what you think of ours? It now stacks five crates and is 3 pounds underweight.
