What is an excavator?

An excavator is a construction vehicle used to dig or move large objects. It is made up of two parts: a driving base and a powerful boom arm with an attachment designed for digging. The operator sits inside a small cab attached to the base and controls the arm.

The base has two sets of articulating tracks that are attached to the side of the excavator. The tracks operate like wheels to move the unit, but provide a larger surface area that creates in a more stable base for the machine. On top of the base is a platform that rotates between 180° and 360°.

An excavator is designed for use on construction sites and is quite expensive to purchase. Many smaller construction companies lease or rent these units to avoid the expensive overhead costs. The lease and rental rates vary, depending on the length of the contract, the location, and the volume of business with the leasing firm. The more equipment that a company leases or rents from the same firm, the better the pricing will be.

All operators are required to obtain a license for the safe operation of this machine. Failure to obtain this qualification can result in a construction site being closed by the workplace health and safety inspector until a valid certificate holder is available to operate the equipment. In addition, many insurance policies are void if the equipment is not operated by a properly licensed operator.

Excavators come in a wide range of sizes and capacities, and the heavier the unit, the greater the lift capacity will be. Some are small enough to fit through a standard doorway, while others are much larger. The most important factor for a person to consider when looking at smaller excavators is the amount of workgroup movement. The greater the degree of mov

When selecting an excavator for purchase or rental, the construction worker should carefully consider the work that he or she plans to do with it. He or she should make sure that the weight capability is large enough to safely accommodate his or her requirements. The person should also explore the different accessories and hydraulic systems in place to find one that will work best for him or her.
