The document provides an overview of draglines, a type of heavy equipment used for civil engineering and surface mining. It details the basic components, types (crawler, wheel, and truck mounted), applications, manufacturers, operation, costs, advantages, and disadvantages of draglines. Draglines are known for their ability to excavate deep and can efficiently handle soft materials, although they have higher capital costs and lower digging force compared to power shovels.

- 3. Dragline falls in heavy equipment’s category. Dragline excavator is used for civil engineering projects and surface mining. Dragline is the largest equipment ever built on this planet. It has the ability to excavate very deep down the earth. Word drag is used because it has the ability to drag material at far distance from the machine. INTRODUCTION 3

- 7. Crawler mounted draglines low travel speed suitable for soft ground. 7
- 8. Wheel mounted draglines high travel speed suitable for firm ground 8
- 9. Truck mounted draglines same as wheel mounted 9
- 10. APPLICATIONS Most suitable for digging softer material. Useful for excavating trenches. Mostly used in excavating canals & embankments. Suitable for loose soils, marshy land and areas containing water. 10

- 12. OPERATION OFA DRAGLINE The excavating cycle is started by swinging the empty bucket to the digging position, while at the same time slacking off the drag-and the hoist lines. The bucket is so construction that it will not dump its contents until the dragline tension is released. 12
- 13. Hoisting ,swinging, and dumping the loaded bucket follow in that order; then the cycle is repeated . An experienced operator can cast the excavated material beyond the end of the boom. 13
- 15. COST AND DEALER Cost :- $ 5 million to 100 million USD (32 crores 50 lakhs to 650 crores INR) Dealer in India :- SRB Group, New Delhi, India Bharat Earth movers limited, Maharashtra , India 15
- 16. ADVANTAGES it can work on natural ground while power shovel take a pit or trench. hauling units do not have to go into trenchusing dragline. range of working is more than powershovel. excavated material disposed off in on operation. 16
- 17. DISADVANTAGES it has less digging force than power shovel output is less than as compared to power shovel. extremely high capital cost. 17
