Also note that in the history of armed conflict, from way before motorized vehicles existed, handcarts have almost no role. Wagons, sure. Pack animals, sure. But almost no instances of infantry pulled/pushed small carts. Either you carried that shit on your back, or it went in a wagon, or it went on a pack animal, or you did without.
So if Romans couldn’t make handcarts practical for infantry, I doubt it’s going to be that useful in today’s mechanized world.
That only holds 625 lbs; do they make a reinforced version for Walmart customers?
Oh, and I stumbled uponthisthe other day. Apparently ye olde peddlers packed so much stuff on their backs they needed walking sticks just to help bear the weight; yet apparently that was still preferable to pulling a handcart. The roads must have been really bad.
