Other relevant elements that play a pivotal part in the configuration of a crane’s anatomy are the runway and the span. As with the building structure, the runway can become a challenging part depending on the environment in which the entire machinery will be installed in. The runway is vital for allowing the crane to be operable from a set distance and to dictate the speed of the trolley depending on its desired length. The span consists of the gap between the rails of the crane. This feature can alter the overall weight of the equipment and consequently increase the cost production due to the increased amount of material needed for the built.
