working principle of hydraulic excavator ppt

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, ....etc

Excavator: is an engineering vehicle consisting of an articulated arm (boom, stick), bucket and cab mounted on a pivot (a rotating platform, like a Lazy Susan) atop an undercarriage with tracks or wheels. Their design is a natural progression from the steam shovel.
Excavators are used in many ways:
- Digging of trenches, holes, foundations
- Material handling
- Brush cutting with hydraulic attachments
- Demolition
- General grading/landscaping
- Heavy lift, e.g. lifting ....etc

Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining.

The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They are among the largest vehicles ever constructed, and the biggest bucket-wheel excavator ever built, Bagger 293, is the largest terrestrial ....etc

Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the house. The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often 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.
