Excavators are of great importance in construction sites. Excavators are made up of many parts that work together to get the job done. Main Parts of an Excavator As mentioned, an excavator has many parts that work together to get the job done. The most common parts are: Motor: it creates the power used in moving an excavator. The motor can be powered by petrol, fuel or even electricity. Its good to note that while there are electric excavators in the market, they are very rare and they are designed to work in specialized areas. The hydraulic motor is one of the most important motors in an excavator. This is the motor that raises and extends the excavator arm.
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.
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.
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.
