My concern is moving the dolly, by hand, as little as possible.
I see younger drivers getting their front box with a dolly attached positioned in front of their back box, then disconnect the dolly and struggling with it, trying to drag or push it in front of the back box. I'm talking 20 or 30 feet.
I won't do that. It's too easy to get injured that way. Plus, it just makes the job harder.
Learning how to do a hero hook is a handy skill to have. When you're trying to learn it, it's frustrating, and seems impossible. But like anything else, once you do it a few times, it becomes easier.
It’s easier to learn in a spotter, but it’s all about getting a feel for how that dolly is going to move and how to correct it before it does.
