mechanical engg seminar topic on hydraulic excavator free download
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 and placing of pipes
- Mining, especially, but not only open-pit mining
- River dredging
- Driving piles, in conjunction with a Pile Driver
Though many companies produce Hydraulic excavators today. Komatsu is the top producer of Hydraulic Excavators worldwide, for every one competitive model there are three Komatsu Excavators
Types of excavator:
- Compact excavator
- Dragline excavator
- Long reach excavator
- Steam shovel
- Power shovel
- Suction excavator
