I have the exact same type, it has a normal car nipple.
But today I move cabs on self made heavy-duty "doggies". I make them slightly larger than the cabs, so they don't bump into door posts. The Gamma-cart you show is too short, you often can't reach the grips with a cab on it, and you often don't see what you are doing.
