A dragline excavator. A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes and the heavy units which have to be built on-site. Most crawler cranes with an added winch drum on the front can act as a dragline.
Our draglines are built with customer-inspired innovations that help optimize their performance, with boom lengths and bucket capacities to meet your specific requirements. 9010C. Bucket capacity 55 - 80 yd³. Boom length 275 - 350 ft. 9020C. Bucket capacity 75 - 117 yd³. Boom length 300 - 405 ft. 9020XPC.

In strip mining operations, draglines are used to remove overburden from mines. Unlike most mining equipment, the bulk of draglines are not diesel-powered. Their power consumption relies on a direct connection to the high-voltage gride at voltages of between 6.6 and 22kV. A typical dragline can use up to six megawatts during normal digging ...

The drag rope of a dragline excavator passes over a lower sheave and then under an upper sheave as it is payed out from a drum in the excavator housing. The two sheaves are oriented to deflect the drag rope downward a predetermined angle as it passes between them. This orientation insures that the rotation of both sheaves is controlled by frictional …
