Before and after One of the biggest individual fabrications that CEC Fabrication Construction regularly refurbish is dragline buckets that are used on the coal mines. Each individual unit can weigh up to 68 tons. It is an Australian designed product that can take a load of 93 cubic metres of coal per drag.
Draglines remove dirt to expose coal and other minerals underneath. Some of the biggest machines can lift several hundred tons in a single scoop, and the bucket alone is about the size of a twocar garage. The machine house is 100 x 118 ft. with a 350 ft. boom and currently uses a 100 CY bucket. The PH 9020 has only been in operation since ...
Draglines are really interesting mining machines. "Having produced dragline buckets and rigging for over 90 years, and having produced more than 8700 dragline buckets during that time, we are continually learning," he said. "Learning and innovation are the most exciting part of this product."
With over 100 years of experience, our mining capabilities are extensive. We leverage our vast experience in true partnership to achieve your goals. As the largest lignite producer in the, we operate mines with annual production levels ranging from a few hundred thousand tons per year to more than 10 million. We specialize in reserve ...
It was detected from failure statistics that operations of Dragline1 and Dragline2 were halted for 938 and 903 times due to failures, yielding total breakdown duration of 13,954 and 16,471 h, respectively. Quantitative contribution of each subsystem to maintenance numbers and maintenance breakdowns can be viewed in Figure 2.

Type the code from the image. Achieving high productivity from large capital equipment items such as draglines depends on consistent fragmentation and muckpile presentation to reduce rehandle and unnecessary movements. By careful planning and blast design, cast to final spoil can be maximised without increasing the risk of flyrock or overpressure.
