Excavators: A Condensed Soup

Submitted by: Robert Tate

Innovation; it is what drives the people of the world to a better life. It is innovation that allowed the excavator to come into being. The excavator is a vehicle that is composed of a moveable arm attached to a bucket for scooping, as well as an operator s cab mounted on a rotating platform. These sit atop an underbody with either tracks or wheels, depending upon the application. Excavators are commonly used in the digging of trenches and foundations, material handling, demolition, river dredging, mining, and grading and landscaping.

The vehicle itself is produced in a wide variety of shapes and sizes. Smaller vehicles are called compact excavators while larger ones are simply called excavators. Recently, hydraulic excavators have opened up new possibilities in the capabilities of the machinery. The equipment is now capable of compacting, pulverizing, hammering, and grappling objects through the use of attachments. Several newer excavators include quick-attaching mounting systems to simplify the attachment process on the job site. Another advancement in the potential of the machinery occurred in the early nineteen-nineties. The Komatsu Engineering Company noticed that a counterweight that was built into the rear of machines to provide more lifting capacity obstructed the excavators ability to turn in constricted areas, thus rendering it relatively useless in such situations. Therefore, the company launched a prototype model that eliminated the counterweight design; this type of machinery is now extensively used throughout the world.

Akin to many things, the realm of excavators has its own language, so to speak. There is a distinct set of vocabulary that is associated with the machinery; the devices themselves are sometimes referred to as diggers or three-hundred and sixty degree excavators. Also, excavators are sometimes called front hoes because of the location of their bucket. An excavators bucket moves in the same way as a backhoes’ — that is, toward the machine. Therefore, the previously mentioned term is incorrect.

An interesting side note is that excavating technology has even made its way onto Mars with the one of the exploration rovers. It features a robotic excavating arm controlled by an embedded operating system or the NASA Operations Center on Earth. The excavating arm is festooned with a bucket, auger, camera, and various sensors; the system has failed many times, however. This is because of the intense weather conditions on Mars.

Essentially, excavators are what have driven the world into this age of technologically advanced buildings and cities. The excavator is an advanced piece of machinery, complete with a bucket, articulated arm, and tacks or wheels. It is used for digging, auguring, mining, material handling, and many other things. Modern excavators allow for the use of many attachments such as drills and grappling devices. It has its own set of vocabulary that is used to describe the equipment itself and various attachments. All in all, the excavator is a beautiful vehicle in both the engineering sense and design. The excavator is an innovation. Perhaps you will one day create an innovative product too.
