Holly Crap a wild ride

My---folks are saying lack of traction with just moisture. Four tires that are meant for hauling extreme weight that are essentially slicks with a few lugs. And a toboggan also, requiring a very rough surface {like rock} for traction. A mine that has no rock piled around?

Oh yess--I was smite'd by a lurker of low ability and unimportance.

Fun times. Our 777s had oversized buckets on them. It was not uncommon for them to end up on their side. Those trucks must be tough, cause I don’t remember any major damage. The mine finally locked out the last gear and that greatly reduced tip overs. Imagine if berms weren’t built on roadways. I road that berm all the way to the bottom of the ramp more than once.

Usually apart from a bust mirror or two and maybe the end of an exhaust pipe flattened nothing serious ever happened to any truck that was put on its side, basically because nothing major protrudes past the body sidewall. I well recall back in the late 70s with early-model 777s operators spinning them on purpose in the frost on the way down into the hole when work kicked off at 0-dark-30 on a Monday morning - no weekend work in those days. It was considered to be no bigge back then.

There should be a counterweight installed on the front bumper of the tow truck but if this was a home-brewed deal maybe whoever built it figured they didn't need one. Whoopsie.........

An important consideration is that the largest truck they have is a 793, so not as much weight would be needed as in your photo of a larger truck being towed.

Once a vehicle starts spinning it loses the coefficient of friction and that will make it slide even worse than if the tires were stopped. When my former neighbor got his first 4x4 truck he figured if he put it in reverse after locking the brakes on ice it would slow down faster. Nope, the spinning tires wouldn't allow any traction and would make it slide further. That's why anti-lock brakes are good idea.
