Definition and Development History of Excavators
Excavators are heavy construction equipment used for digging and excavating materials, such as soil, rock, and debris. They consist of a boom, stick, and bucket, which are controlled by hydraulic systems to perform various digging and loading operations.
The history of excavators dates back to the late 19th century, when steam shovels were used for excavating materials for construction and mining projects. These machines used steam power to operate a shovel that lifted and moved large amounts of material.
In the early 20th century, the development of gasoline engines and hydraulic systems led to the creation of the first hydraulic excavators. These early machines were powered by gasoline engines and used hydraulic systems to control the movement of the boom, stick, and bucket.
Over time, advancements in technology led to the development of diesel-powered excavators, which became more efficient and powerful than their gasoline-powered counterparts. In the 1950s, hydraulic excavators also began to incorporate new features, such as hydraulic quick-couplers and other tools for more efficient excavation.
In the 1970s and 1980s, the use of computer-aided design technology helped to improve the productivity and precision of excavation projects. Excavators now incorporate advanced features, such as GPS navigation, telematics, and remote control systems.
Today, excavators are among the most common types of heavy equipment used in construction, mining, and other industries. They are available in a wide range of sizes and configurations, from small mini excavators used for residential construction projects, to large mining excavators used for extracting vast quantities of materials from the earth. Excavators have revolutionized the way that earth is moved, enabling faster, safer, and more efficient excavation of materials needed in construction, mining, and other industries.
