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 standar 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.

The larger types are used in strip-mining operations . There are two draglines working at RGOC-I and RG OC-III with bucket size of Cum and 30. Both these draglines are performing very well. The bucket is maneuvered by means of a number of ropes and chains. The first dragline of any kind to be successfully equipped with AC IGBT drive systems, we developed this superior technology for the sole purpose of making .

The most important feature of draglines, however, was their ability to dig deeper overburden depths than the stripping shovel could effectively handle.

Often these draglines were used in conjunction with a shovel wherein the dragline excavator would take the top portion, or soil above the rock portion which would have to be. The superstructure comprising power unit, winch, cabin and boom rotate on this base. The machine is usually situated on a bank Fig.

The operating load capacity of a dragline depends a great deal on the material dug, the bucket use and the boom angle. As in the case on any crane- type equipment, the capacity of the dragline excavator is increased by using a higher .

The dragline boom is usually set for an angle between 25° and 40° with the horizontal. This technology image could be recreated using vector graphics as an SVG file. The principal differences between it and the power shovel are in the design of the superstructure and in a longer boom.
