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.
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.
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.
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.
