Excavation that uses the power of high-capacity machines is nowadays a basic and indispensable part of any construction project – almost all building sites around the world today use machine digging. However, the industry of machine excavation is relatively new – for hundreds of years, backbreaking digging work was done by humans who used manual shovels. The idea of building a machine that could move the soil came only with the Industrial Revolution – the first attempts to create such a machine were recorded in 1880. The very first excavation machine was built in 1882, by Sir W. G. Armstrong’s company in England and it was used for digging the plot for the docks in Hull. The equipment used water for the machine’s hydraulic digging functions and it was not considered sufficiently efficient, so the design process continued with lots of improvements. The first system that replaced water with all-hydraulic cylinders was built in 1897 – the machine had only a few, simple components and was able to deliver much more power than its predecessor.
The evolution of the excavator – and with it, the evolution of the entire industry – continued during the 20th century as well: in 1948, the first wheeled unit was launched and the first telescopic boom excavator also came out during that year. The development of new features continues even today, one of the most important development being the deployment of the combined power of water and vacuum with machines called hydroexcavators. Many of the Denver contractors utilize the newest technologies to help their construction projects come to completion in a timely matter.
