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.

Excavator rental services Excavators can be seen digging up earth rocks and even concrete rubble in any construction site today which can be on absolutely virgin land where no construction work had taken place earlier or it could be a reconstruction project. The project manager builder or contractor in charge of the site decides whether to get equipment like excavators for rent or purchase them outright. It is entirely up to the project in-charge to make the decision about going for outright purchase or opt for rental services to optimize cost.

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.
