Excavators are engineering vehicles which are primarily used for the purpose of digging trenches holes or foundations. They are also used for other purposes such as demolition lifting and placing heavy materials especially pipes for mining( not open pit mining) river dredging landscaping. These can be used for brush cuttings aided with hydraulic attachments. Because excavators are used for the purpose of digging people usually use the term excavators for all kind of digging equipments. Actual excavators have an articulated arm a bucket and a cab mounted on a rotating platform known as a pivot. This platform is on top of an undercarriage with tracks or wheels. The design is basically derived from steam shovels.
Excavator rental services Excavators can be seen digging up earth rocks and even concrete rubble in any construction site today which can be on absolutely virgin land where no construction work had taken place earlier or it could be a reconstruction project. The project manager builder or contractor in charge of the site decides whether to get equipment like excavators for rent or purchase them outright. It is entirely up to the project in-charge to make the decision about going for outright purchase or opt for rental services to optimize cost. There are construction companies that are structured in a way where they operate with huge in-house inventory of heavy duty equipment while many others like to operate with very little in-house inventory and avoid such capital expenditure.
Bucket Wheel This one comes with a large front wheel that is equipped with buckets and built-in shovels. As the wheel rotates the buckets scoop up dirt rock and transfer it to a conveyor belt. The belt then carries earth into a bin. Dragline A dragline excavator features a design similar to that of a backhoe. It includes a series of cables and lines to support the pulling motion of the bucket. The design of the excavator allows you to dig deeper than the standard backhoe. The cables and long boom also helps you to operate the excavator over wet or unstable ground. Suction This excavator uses a large diameter hose to suck earth and rocks out of the ground using vacuum technology. Due to the technology the excavator is ideal when you use it to dig around pipes and other underground objects.
Moving on the to the possible non-NASA commercial application it can be said that the same qualities of the LPE that apply to space would also attract terrestrial users or said differently us earth bound creatures. As both business and government markets rapidly expand so does the need for urban infrastructure. Using NASAs own words on the subject; Urban construction settings restrict the use of explosives to minimize damaging vibrations making mechanical methods attractive. In addition shallow tunnel construction is rapidly changing from cut-and-cover to wholly underground because excavations disrupt city traffic. Coupled with increasing population these factors enhance the market for innovatively flexible systems such as the LPE. If I could have said it better than NASA did I would have. But I couldnt so I didnt. Anyway there you have it both the past of excavators and a look at their future with the development of the Low-energy Planetary Excavator
