Whether a construction project is big or small an excavator is an important tool that companies should have. An excavator is a tracked vehicle with a bucket in front and an approximate operating weight of 0.7 - 7.5 tons. The bucket that is seen in front of the tracked vehicle tilts to dig out a particular area. For bigger projects a full size excavator is used to perform the job. However for those areas where it is difficult for full size excavator to access a mini excavator is used. Mini excavators are very mobile and are suitable for this kind of construction projects. Nowadays most companies favor mini excavators because of its mobility and flexibility. It can easily be maneuvered to reach a narrow part of the area. Also another good reason is that it is suitable to any other attachment. Since the primary purpose of this is to dig out the ground other attachments attached to the excavator can improve the quality of the construction job and perform other tasks.
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.
Other Factors to Consider When Choosing Used Excavators You should also think about the digging depth that your jobs require. A larger digging depth is going to require a bigger machine. Consider your working radius. Is there enough room for the excavator to get in and get the job done. If you are working in a small area you may have to go with the smaller used excavators. A good idea when thinking about buying used excavators is to consult with the manufacturers specifications of the machine just to make sure that it can get the job you need it to do done.
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.
