The Australian coal mining industry operates a large dragline fleet such as is shown in Figure 1. The draglines generally work 24 hours a day, 364 days a year. The productivity of each dragline is generally estimated to be around $8000/hour and thus the cost of any unscheduled down time is very significant for the operation.
The larger designs are most often used for mining operations instead (1). Transport of large dragline excavators isn't common, as they are purpose-built on site and weigh anywhere from 8,000 - 13,000 tons. In contrast, their smaller counterparts are often transported - as they are built to be dismantled and loaded onto trailers.
The dragline has a base diameter of 18m and working weight 3,420t. The maximum dumping height and digging depth of the ESH 30.110 are 46.2m and 53m respectively. The dragline is equipped with three 1,120kW drag motors, …

For large mining operations a bigger, heavier dragline excavator is needed. This type of equipment must be built onsite. It would cost too much to transport. These huge dragline excavators are meant to stay in place – and in service – for decades. Onsite dragline excavators are typically used in coal and oil sands strip mining.
