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
Excavator Arm: The arm is attached to the lower part of the frame chassis and has two main sections that are joined with a hinge. The sections have pistons that move them. When the first piston extends the rod pushes against the arm and raises it thus extending the section. The second arm then contracts and expands thus raising and lowering the second section. To help the excavator to scoop and dig the arm has a bucket loader. Tracks They are rigid and fixed in one place. The tracks are stationed around a series of gears that turn after receiving power from the drive shaft that is connected to the engine. When the tracks are in gear they roll the excavator backward and forward in a straight line.
The Dragline Excavator may come in smaller or bigger types. Smaller types are employed in civil engineering to construct road and port. While the larger types are utilized in strip-mining to move overburden above coal and for tar-sand mining. Draglines usually weigh about 2000 metric tons but there are also bigger draglines weighing 13000 metric tons. The bucket system of a dragline has a large bucket suspended with wire ropes from a large truss-like structure called boom. This bucket is maneuvered by ropes and chains and is supported by a hoist rope (whose power comes from large diesel or electric motors). The dragrope is responsible for holding and drawing the bucket assembly in a horizontal fashion. A skillful operator may apply his skills in contriving the ropes for the dragline to perform various operations.
This represents the classic excavating machine that available for you. This is also is one of the oldest types of excavators. This excavating machine has almost the same features with backhoe. You will find that this can be very important for doing the excavation projects that you should do. Suction Excavator is the next type of excavator that you can find in the excavation sites. This resembles a modern dump truck. The operators use a hose with large diameter to suck rocks and earth out of the ground. To do this this excavating machine uses vacuum technology. After sucking the earth and rocks they will be transferred into the truck. This excavating machine will make it safe to dig around underground objects like pipes with a reduced risk of damage. This is safer compared to standard backhoes.
