Different types of heavy equipments are used for different applications and purposes. They are most commonly used in performing tasks necessary to complete a construction project. One particular type of heavy equipments (construction equipment earth movers engineering vehicles or just plain equipment) is an Excavator. An excavator mainly consists of a boom bucket and cab on a rotating platform called a House that sits on top of an undercarriage with tracks or wheels. Number of reasons exit for the functions and application of an excavator. Excavators may be used in digging trenches holes and foundations. It could also be used in handling materials and in brush cutting with hydraulic attachments. Forestry works are also made easier and facilitated by the use of excavators.
Excavator Arm: The arm is attached to the lower part of the frame chassis and has two main sections that are joined with a hinge. The sections have pistons that move them. When the first piston extends the rod pushes against the arm and raises it thus extending the section. The second arm then contracts and expands thus raising and lowering the second section. To help the excavator to scoop and dig the arm has a bucket loader. Tracks They are rigid and fixed in one place. The tracks are stationed around a series of gears that turn after receiving power from the drive shaft that is connected to the engine. When the tracks are in gear they roll the excavator backward and forward in a straight line.
Mini excavators are popularly known as compact excavators also the smallest models generally weigh around 1500 kg and they have a bucket size of 0.036 m 3. One thing that sets a mini excavator apart is the fact that all the movements and functions are supported by a hydraulic fluid.. These mini excavators have become very trendy in metropolitan areas because of the limited space available. It can easily get into small spaces where one cannot even dream of bringing in a large excavator. Mini excavators are used for improving the service and reducing the maintenance costs. Mini excavators are generally used for loading the material into a truck setting up pipes and for precision excavating and trenching.
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.
