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.

To remove earth from a hole heavy debris on land or from various places a Suction or Vacuum Excavator is used. It has a wide suction pipe with a diameter of about a foot the suction air inlet air speed may reach 100 meters per second. A steam-powered excavator Steam shovel is designed to lift and move materials such as rock and soil. It is a forerunner of a Power shovel (also called Stripping Front or Electric Mining shovel) which frequently runs on electric power for digging and loading earth or fragmented rock and mineral extraction.
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.
