Suction Excavators Apart from bucket excavators some excavators play the role of a vacuum by sucking out debris and other dirt materials from the ground. The excavation that takes place using a suction excavator requires the use of water in the soil. The water makes the soil loose making it easier for the suction pipe to suck the debris. Suction excavators are used when there is a need to extract soil from the ground for experimental purposes. Long Reach Excavators Long reach excavators have a long arm and boom sections. These types of excavators are usually used in demolition tasks. These machines are strong and can easily break walls and solid structures with power. Their long arms allow the handlers to stay at a safe distance from the demolition debris yet perform the task successfully in less time.
Excavator manufacturers today offer a vast range of such equipment that come in different sizes and capacities. These machines undergo numerous tests ad are designed to perform various functions in construction projects mines and many other jobsites. There are different types of excavators such as compact excavators long reach excavators dragline excavators and amphibious excavators that perform a wide range of functions like digging trenches foundations for huge structures digging holes mining landscaping river dredging and much more. Construction or mining project managers intending to go for excavators on rental basis may consider one or more of such machines and they have enough options to make an informed choice.
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 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.
