If these men had any kinda of intelligence all they would need to do is mark a center guidance point at the end of the bridge place a mark on the blade and keep those to points lined up. It also works when loading or off loading heavy equipment. And when hitching up a tractor trailer and or camper trailer. Unless of course you have a rearview camera.

the running around of the "gunner" always surprises the tractor, is it rubber? Does the goose change the track all the time or what? Well, I got up and figured out how much the goose should go along the edge, and stand still, control one side and the second is by itself relative to this one, well, of course, if the tramp is not "RUBBER"

Roughly 10.3 million Americans are employed in the construction industry. Most of these workers are exposed to dangerous equipment and machinery every day. If something goes wrong, it can change the worker’s life forever—and, unfortunately, there’s a lot that can go wrong.

Some machines are inherently dangerous and may hurt an unfocused or inadequately-skilled worker. Other times, a particular machine, while usually safe, is defective and causes an injury. Still other times, the machine is safe so long as certain safeguards are put in place, but the employer or employee fails to do so.

Depending on the circumstances of your construction accident injury, you may be able to file a workers’ compensation claim or a personal injury lawsuit to receive compensation for your medical expenses.
