We need to do a presentaion on hydraulic excavator for our course at UNSW.

We would appreciate it if you would provide us access to your ppt so as to source information for our work

Thank you

A hydraulic excavator (digger) is a large vehicle that is designed for excavation and demolition purposes. Hydraulic excavators consist of a chassis, boom, and bucket, and move via tracks or wheels. They range in size and function, an example of which is the similar but smaller “mini excavator.” All versions are generally designed for the same purposes. Hydraulic excavators weigh between 3,000 and 2 million pounds and their speed ranges between 19 HP and 4,500 HP.

How Does A Hydraulic Excavator Work?

Hydraulic excavators are entirely dependent on hydraulic systems. The hydraulic excavator’s base/undercarriage consists of a track or wheeled platform and provides transportation for the vehicle while supporting the chassis. The chassis allows the driver to control the hydraulic excavator by using levers to drive the vehicle, raising the boom up and down, and controlling the bucket. Because the chassis is built on top of the undercarriage, it is able to rotate 360 degrees. The boom and bucket are attached to the chassis, work in conjunction to move materials, but are controlled independently.
