Cart has two handle bars for easy load and unload in a Liftrunner B-frame. Four polyamide (nylon) casters where one of the front casters is fixed and the other three swivel. This makes it easy to guide the cart into the right spot. The rear casters are swivel with brake. The shelf position can be adjusted to a different height using standard tools. The shelf also made in one single piece so there are not bolt heads sticking out.
