In terms of heavy machinery, the dragline excavator is one of the largest in the world. This is because they are large, but they also allow mining companies to be highly productive by offering a way to facilitate the transportation and mining of large areas. In addition, most dragline excavators have a service life of 40 years and (pound per pound) are the most productive and versatile machines in mining.

Dragline Excavator Uses

Dragline excavators do not differ much from cranes. However, a dragline excavator is different from how effective it is measured in units such as chassis and counterweight. For example, lift cranes usually have a more significant counterweight than draglines designed to lift heavier materials. However, a dragline excavator can lift weighty materials.

Using a dragline excavator can be very different. As part of heavy machinery, the dragline excavator is efficient in construction and surface mining.

Draglines fall into two broad categories: those on a standard hoisting crane and those heavy units that industries need to build on-site. Most crawler cranes can act as a dragline with an additional winch drum at the front. These units – like other cranes – are efficient for dismantling and moving along the road on flatbed trailers. Draglines are common in civil engineering and are almost always of this smaller type of crane. They are great for projects such as:

  • Roads
  • Port construction
  • Pond and canal dredging
  • Pile driving rigs

On-site equipment is often for other projects, such as strip-mining, to help remove coal and oil sand surpluses, requiring large amounts of land suitable for equipment such as dragline excavators.

Size of Dragline Excavators

The giant heavy draglines are the largest mobile ground machines ever made. The most minor and most common of the heavy variety weighed about 8,000 tons, while the most extensive built weighed about 13,000 tons. Find out more about the giant draglines in the world.

The bucket system consists of a large bucket suspended on a boom (large lattice structure) with wire ropes. The hoist rope, driven by diesel or electric motors, supports the bucket and hoist assembly. Moreover, the drag rope is for drawing a bucket assembly. The operators inspect the container for various operations.
