What is difference between dragline and shovel?

What is difference between dragline and shovel?

A dragline possesses a long jib for digging and dumping and it is used for digging from grade line to great depths below ground. Though a shovel has limited ability to dig below ground level, it is very efficient in digging above ground like digging an embankment.

What are the advantages of dragline over power shovel?

Advantages of dragline over power shovel: A dragline usually does not have to go into a pit or hole for excavating the earth. It may operate on natural firm ground. Therefore it is more useful when the earth is removed from a ditch, canal or pit containing water.

What is a dragline used for?

Utilized in a similar fashion as cranes, draglines are used primarily for open-pit operations to dismantle and transport materials. In strip mining operations, draglines are used to remove overburden from mines. Unlike most mining equipment, the bulk of draglines are not diesel-powered.

What is a front shovel?

A power shovel (also stripping shovel or front shovel or electric mining shovel or electric rope shovel) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction.

What is a clamshell bucket?

The clamshell is a bucket with two hinged jaws carried by a crane suspended from the boom by two lines: one raises and lowers the bucket, and the other pulls the jaws together against gravity for digging action. It is used chiefly for deep, narrow excavations,…

Which of the following is type of dragline?

There are three types of dragline; Wheel mounted dragline. Crawler type dragline. Truck mounted dragline/portable dragline.

What is dragline in construction?

 A dragline is used to excavate the earth and load it into hauling units such as trucks or tractor pulled wagons or to deposit it into dams/ embankments or spoil banks near the pit from which it is excavated.

How much time a dragline may take to complete a cycle for a single pass?

A dragline can be said to have a simple routine of work, which is composed of digging and walking. Mine design team has little control on walking, which is a steady process. Almost all walking draglines take a step of approx. 2 m within a period of 0.75-1 min.

How many types of dragline are there?

How tall is a dragline?

The draglines specifications are: Base – The base is 80 feet in diameter and covers the area of a baseball infield. Boom – The Dragline boom height is 215 feet from the tip of the boom to the ground and the boom is 360 feet long. The Dragline dump height-130 feet, reach depth is 180 feet.

Should I use a shovel or dragline for mining?

Because of the shallow water table, draglines are the preferred solution. (Update: federal regulators are allowing a phosphate mine to expand their operations .) Comments concerning the choice between shovel and dragline. Video of Marion 7820, the world’s largest. It includes walking. It has some big shovels as well.

What is a dragline excavator?

A dragline possesses a long jib for digging and dumping and it is used for digging from grade line to great depths below ground. Its characteristic is that it does not possess positive digging action and lateral control of normal excavators. A dragline is normally deployed for bulk excavation.

Can a shovel be used to dig below ground level?

Though a shovel has limited ability to dig below ground level, it is very efficient in digging above ground like digging an embankment. This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.
