In the early days of construction, laborers would use manpower and ramps to get building materials into place. Today, cranes make it easier to lift and move hefty materials for all types of construction projects. To better illustrate this important development in construction machinery, here’s a brief timeline of the crane and how it has evolved.

The History of the Crane

Ancient Construction

The earliest record of this lifting technology dates back to Ancient Greece around 515 BC. Inspired by the pulley systems originally created in Mesopotamia, Greek builders utilized a three-pulley device to lift small stone blocks. Powered by men or donkeys, these early cranes made it possible to build tall buildings using smaller labor forces.

Romans built upon the Greek’s invention by creating a three-by-five pulley system. The extra components made it possible to lift loads up to 6,600 pounds.

Harbor Use

After the Roman Empire fell, European civilizations in the Middle Ages began using cranes with treadwheels, which are manual engines that look like water wheels. The added power of the treadwheel made it possible for seafaring crews to load and unload ships at harbors.

Industrial Innovations

As the world approached the Industrial Revolution, wood systems were eventually replaced with a stronger cast-iron design. A stationary hydraulic-powered crane was developed around the same time, and it quickly became a staple for lifting loads at docks and railways.

Modern-Day Machinery

The hydraulic model took its next step in the 1940s when Roy O. Billings created the hydro crane in America. This piece of construction machinery offered enhanced mobility, as it was mounted on a truck.

The truck-mounted concept continued to evolve, and its modern variations can be used by ship and air. From the self-erecting tower crane to the mini crane, today’s wide selection of equipment has made it possible for crews to utilize impressive lifting power in all types of environments.
