Heavy construction equipment with a hinged metal bucket attached to a hydraulic arm, used for lifting is known as a digger. Diggers are also known as excavators. Diggers help in maximising productivity and are widely used in the process of construction. There are generally four major parts of a Digger- boom, bucket, cab and house.
Diggers are widely used by construction companies for various purposes. A cable-operated Digger works using winches and steel ropes for the movements. A Hydraulic Digger uses hydraulic fluid, with hydraulic cylinders and hydraulic motors for movements.
Different Types Of Diggers:
- Drag Line Digger: It is used in civil engineering and surface mining. The largest heavy Drag Lines are among the largest mobile land machines ever built.
- Steam Shovel: Steam shovel is the earliest type of Digger. It was designed to lift and move rock and soil.
- Power Shovel: It is a bucket-equipped machine, which is powered by electricity. It is used for mineral extraction and for digging fragmented rock.
- Suction Digger: It is designed to remove earth from a site, or remove heavy debris on land, by powerful suction. It functions using a wide suction pipe, which is about a foot in diameter. The suction inlet air speed is typically about 100 metres/second (224 mph).
- Compact Digger: It has an approximate operating weight ranging from 0.7 to 8.5 tonnes and generally includes a backfill blade and independent boom swing. It is also known as Mini Digger.
Uses Of Diggers:
- Digging trenches, holes or foundations
- Material handling
- General grading/landscaping
