 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.

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.

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.

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.

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.
