A knowledgeable customer would like to know the machines engine output ground level reach boom swing etc. to figure out if the excavator meets his requirements or not. Project managers who want to check excavator rental services can log on to aggregator websites that are essentially portals where tens of thousands of hirers of construction equipment visit regularly looking for good deals. These websites are convenient for hirers to check thousands of suppliers offering scores of equipment variants on a single platform at competitive rates and in the most transparent manner. It is really easy to look up rates features and advantages of excavators from all the different brands after a customer gets used to a portals navigation. Hiring excavators on rent online may be easy but users must take the trouble of researching the portal for information on its reputation and reliability.
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.
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
In case youre now wondering what 3D and VRML or actually x3D has to do with excavators that is something we will be getting to in other articles for right now youll just have to trust that there is a fit. For now however lets get back to excavators the digging machines used for but not limited to: Digging demolition minning river dredging heavy lifting and with hydraulic attachments brush cutting. It is these same hydraulic attachments that have expanded the use of excavators far beyond their original use of excavation such as the Low-energy Planetary Excavator (LPE) proposed by NASA. The latest paper to be found on this Nasa proposal is for 2006 so the current status can only be guessed at nevertheless the concept is certainly intriguing as are the LPEs possible commercial applications.
