In a way it seems like a contradictory idea. How can a machine be producing 'over capacity' if capacity is the limit of its ability?

When elevators are designed, engineered and built, all the technical data connected with the materials used, their ability to carry loads, and changes that occur to materials during use (related to heating up, for example) all go into a careful estimate of what the elevator can safely carry, and probably also an estimate of the absolute maximum load, which if exceeded, would cause failure. But these are theoretical, or mathematical estimates of the elevator's ability. Given any number of factors, a specific elevator may be able to carry a load larger than the calculated limit for some length of time. But weights just a little over normal safety capacity would cause more rapid wear of the system, and would probably not cause catastrohpic failure.
