The other terms used for excavators are diggers and 360-degree excavators. They are sometimes simply called 360. The tracked excavators are also called track hoes due to its resemblance with a backhoe. There is a contradiction that the back in a backhoe is used in reference to the pulling back action of the bucket towards the machine instead of the location of the shovel. However excavators are still referred to as front hoes by some people. Excavators come in a variety of sizes but the most popular are large excavators and mini excavators. The large excavators are huge in size. They weigh around 85000 kg and their bucket size is usually 4.5 m 3. These excavators are generally used for industrial excavation works.
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.
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.
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.
