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
Dragline Dragline excavators are bigger in size and mainly used for big-scale construction practices including n-surface mining and other civil engineering tasks. These excavators are available in two different types; on-site and standard mobile draglines. Due to their huge size these excavators are often transported to the site in unassembled parts to be assembled onsite. On-site draglines are massive and built onsite and used for canal dredging. These draglines are also quite heavy which is the reason they cannot be transported in one piece as they may cause damage to the roads.
A closer look at excavators All excavator movement and functions are accomplished with the use of hydraulic fluid hydraulic cylinders and hydraulic motors and that explains why they are also known as hydraulic excavators. The main components of these heavy duty machines comprise of bucket boom dipper or stick and a driver cab on rotating platform. The operator cabin is also known as house in construction industry language and it is attached to the undercarriage which enables the excavator to rotate 360 degrees all around. There are also other attachments that are used for different purposes like boring crushing and other functions in addition to the main set of components.
When you have an excavating job to do it is always a good idea to get the right machine for the job. When you get a machine that is too big for a job then you end up having wasted money and wont get what you need out of the excavator. That is why in many cases it is a good idea to use used excavators rather than invest a lot of money in new equipment. What to consider when choosing used excavators It is important that you figure the cost per excavation and the condition of the job where the excavator will work. These are extremely deciding factors when choosing the type of used excavator for the job.
