We overloaded one today. Moving machines into the new hobby shop entailed loading the pictured Swiss Jig Borer [which weighs at least 5000lbs, maybe 6500lbs] onto a 3/4 ton pick-up. Note the squashed tire on the fork truck. Even it is overloaded. The tire on the other side is about to run over the chain that lashes the machine to the mast. Yes, forward motion suddenly stopped when the chain got taunt. Squatted the truck and bulged the rear tires. So my eldest son [the guy driving the lift truck] pumped up the rear tires to 80 PSI. That made it look a little better. The last two miles is over a primitive road. Never saw a lawman and got away with it. It looked pretty bad but not as bad as the guy hauling a complete car in his small pick-up.
