Historical Overview:

The evolution of cranes spans millennia, reflecting humanity's ingenuity and resourcefulness in overcoming the challenges of construction. Ancient civilisations, such as the Egyptians, Greeks, and Romans, laid the foundation for crane technology with their inventive use of simple devices like ramps and pulleys to lift heavy objects. The iconic pyramids of Egypt and the grand temples of Greece stand as testaments to the effectiveness of these early crane mechanisms. However, it was during the Middle Ages that cranes began to take on more recognizable forms, marking a significant advancement in construction technology. Wooden treadwheel cranes emerged as prominent features of medieval construction sites, utilising human or animal power to hoist materials to great heights. These cranes revolutionised building practices, enabling the construction of towering cathedrals, fortified castles, and monumental city walls across Europe.
