![]() ![]() if you move your hand closer to the dirt (reduce the overhang) the leverage will also be improved.if you make the handle longer (get a car with a longer wheel base) the leverage will be improved and.if you get rid of some of the dirt (reduce the ball weight) the loads will be less.To continue the analogy with the shovel, if you move your right hand towards the dirt it will become easier to lift and if you try to lift nearer the handle end of the shovel it will be much more difficult. If you wanted to lift that dirt, its effective load would be ‘increased’ depending on where you held the shovel with your right hand but it will always be heavier than the weight of the dirt itself. ![]() Imagine if you had a shovel of dirt with the handle horizontal, and the handle end of shovel was held in your left hand. Luckily, we can turn to Archimedes (born in 287 BC) and his teachings in regard to levers. Whichever is the lesser, is the maximum amount of load you can place on your tow bar when hooking up a trailer (caravan, camper or box).īut, what does that weight really mean when you look at the bigger picture of loads on the tow vehicle (sometimes called the ‘tug’). Your car and tow bar has a maximum tow ball weight. ![]()
