Over time, significant crane design advancements evolved. For instance, a horizontal boom was added to and became known as the jib. This boom addition allowed cranes to have the ability to pivot, hence greatly increasing the range of motion for the machine. Following the 16th century, each side of a rotating housing which held the boom incorporated two treadmills.

At the turn of the century, IC or internal combustion engines and electric motors emerged. Furthermore, cranes became designed out of cast iron and steel rather than wood. The new designs proved more efficient and longer lasting. They could obviously run longer also with their new power sources and thus complete bigger tasks in less time.
