During the first century, cranes were built to be powered by animals or humans that were moving on a treadmill or a wheel. These cranes had a long wooden boom known as a beam. The boom was attached to a rotating base. The wheel or the treadmill was a power-driven operation which had a drum with a rope which wrapped around it. This rope additionally had a hook which was attached to a pulley at the top of the boom and carried the weight.
Cranes were used extensively in the Middle Ages to build the huge cathedrals within Europe. These devices were also used to unload and load ships within key ports. Over time, significant crane design developments evolved. Like for instance, a horizontal boom was added to and became known as the jib. This boom addition enabled cranes to have the ability to pivot, therefore greatly increasing the equipment's range of motion. After the 16th century, cranes had incorporated two treadmills on each side of a rotating housing that held the boom.
Cranes used animals and humans for power until the mid-19th century. This all changes quickly once steam engines were developed. At the turn of the century, Internal combustion or IC engines as well as electric motors emerged. Cranes also became designed out of cast iron and steel as opposed to wood. The new designs proved longer lasting and more efficient. They can obviously run longer too with their new power sources and hence carry out larger tasks in less time.
