A closer look at excavators All excavator movement and functions are accomplished with the use of hydraulic fluid hydraulic cylinders and hydraulic motors and that explains why they are also known as hydraulic excavators. The main components of these heavy duty machines comprise of bucket boom dipper or stick and a driver cab on rotating platform. The operator cabin is also known as house in construction industry language and it is attached to the undercarriage which enables the excavator to rotate 360 degrees all around. There are also other attachments that are used for different purposes like boring crushing and other functions in addition to the main set of components.
In construction especially of large infrastructures an excavator is operated to assist in demolition general grading landscaping and in lifting and placing heavy objects such as pipes. Excavators also aid in mining river dredging and driving piles. A Compact hydraulic excavator or mini excavator has tracks or wheels and weighs approximately 0.7 to 7.5 tons. Caterpillar the worlds largest manufacturer of construction equipments has a compact or mini excavator that weighs only 1610 kilogram or 3549 pounds and operates on a power of 19 hp. The mini excavator by and large consists of a standard backfill blade with independent boom swing. It is different from other heavy equipment in such a way that a transfer of hydraulic fluid in hydraulic cylinders is responsible for all the movements and functions of this machine particularly its work group and blade. The compact excavators rotation and travel functions are as well activated by the hydraulic fluid-powered motors.
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.
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.
