Excavators are the cornerstones of projects as far as civil engineering and construction projects go. It is more than a vehicle project manager’s use for excavating and moving large objects. Excavators at the beginning consisted of two primary parts which are:

• A base for driving linked and in control of a powerful boom arm with an attachment resembling a bucket with teeth designed for excavating. The operator or the driver of the excavator inserts himself into a small cab connected to the base where the controls for the arm are located.
• The second component is the Hydraulic system that the excavator is fitted with which generates Hydraulic force that moves the mechanical arm. Excavators either come with a chain wheel system or standard wheels. However, nowadays there are excavators with spider like legs that provide better support and stability for the machine when working in unstable, soft and muddy ground.
