A dragline excavator is a heavy-duty excavator used in civil engineering and surface mining. It was invented in 1904, and presented an immediate challenge to the steam shovel and its diesel and electric powered descendant, the power shovel .

Cat® Draglines are a primary excavating tool in many surface mining operations worldwide. They're highly productive and offer the lowest material cost per tonne in the industry.

Cat® draglines offer the lowest material removal cost per ton, consume less power and emit fewer greenhouse gases than other methods of overburden removal, making them the most productive and environmentally friendly excavators in the industry. The Cat® 8750 is our flagship model.

Advanced structural analysis, CAD modeling and high-tech gearing software have been utilized to create a dragline designed to deliver outstanding long-term cost-effective productivity and reliability.

Cat draglines offer the lowest material removal cost per ton, consume less power and emit fewer greenhouse gases than other methods of overburden removal, making them the most productive and environmentally friendly excavators in the industry.

The dragline, or dragline excavator, is a mechanized excavator and crawler that is used in large-scale works. It operates with a shovel or scoop attached to the machine only with cables, which offers it a wide range of action and load.

May 17, 2020 · 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 …

As far as heavy-duty machinery, a dragline excavator is among the world’s largest. They are not only massive, but also provide mining construction operations the ability to be highly productive by offering a way to streamline hauling and excavation of large areas.

Dragline excavators have become bigger, stronger, and more efficient. Today, these machines can dig over 50 meters deep and move up to 6,000 tons of material within a day. The world's biggest dragline excavators are worth a look for an impressive display of engineering and engineering prowess.

Aug 16, 2012 · 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.
