Excavators

Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic Fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements.

How do Excavators work?

The operator of the excavator uses pedals and levers to steer the equipment and to move backward and forwards. Tracks, similar to tank tracks, are activated by the diesel-powered engine, and hydraulic motors control the arm of the excavator. While you no longer need to possess an excavator licence to operate an excavator for typical excavation jobs, you will need to prove competency in way of certification.

What are the different sizes of Excavators?

Mini or Compact Excavator - This is the smallest class of excavator and they are particularly useful for fitting into small spaces.
Midi Excavator - Midi or mid-sized excavators are a good choice for those who work in small spaces but need more reach and power than a mini excavator can provide.
Standard Excavator - Standard or full-sized excavators, sometimes called “crawler” excavators, make up the largest volume of excavators on the market.
Large Excavator - The largest class of excavators is useful for major construction and demolition projects that require the maximum of power and capacity.

Excavator Skills and Qualifications

Excavators operate heavy machinery on a variety of construction projects.

Workers in this role typically have at least a high school diploma and the following skills:

Machine operation skills – excavators need to be very familiar with the principles of machine operation, including both excavators and related machinery such as bulldozers and trucks
Physical stamina – this role frequently requires long days of operating machinery, as well as climbing in and out of an excavator, so physical stamina and strength are both necessary
Safety skills – construction machinery can be hazardous to operate, so excavators should also have a solid grasp of safety procedures and best practices for responsible operation
Team collaboration – excavators work with construction crews, site engineers, and surveyors to determine the scope of excavation projects, so effective team communication and coordination are important
Accuracy and attention to detail – this role also requires excellent attention to detail and a high level of accuracy to ensure proper dimensions while digging for construction projects
