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.
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
Excavators are one of the greatest engineering tools that have been manufactured to this date. These heavy machines are steady strong and extremely efficient. They are extensively used in construction work and other civil engineering tasks. These solid tools dig up the soil and carry huge amounts of debris and move them from one place to another. Furthermore these machines also play a major role in crushing and leveling of the land for construction purposes. This excavator technology has made some prominent advances and thats the reason we can find a number of different types of excavation buckets in the market. Lets take a look at these types in detail.
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.
