However the counterweight makes it difficult to maneuver the vehicle as it extends beyond the tracks. The zero tail swing excavators on the other hand have a counter weight that doesnt extend over the rails and hence make it easier for the operator to maneuver. Excavators are mainly defined or specified by their arm force dump height power rating and their dig depth. Originally all excavators came with the bucket as the only attachment. However current exactors have a variety of attachments such as grapples breakers and augers. The buckets also come in different types e.g. tilt general purpose and sorting buckets. The operator can control the side to side angle of tilt buckets while sorting buckets are used to separate large materials from the smaller ones. The quick attach mounting system makes it easier for attachment switching at the site. Lee is an experienced and competent writer especially in business and construction industries.

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.
Back Hoe For excavation purposes construction engineers make use of back hoes which are the most common types of excavators used today. This excavator has a bucket attached to the front which is facing the driver. This position of the bucket allows the driver to have a clearer idea of the excavation. Back hoe excavators are part of almost every construction site and due to their incredible ability to dig through soil they help improve productivity and save costs. The cab of this machine can swiftly rotate to 360 degrees making it easier for the driver to transport the debris to the dumping zone. Back hoes are also used for clearing snow covered roads and to clear blockages.
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
