Miner with Big Trucks
Axis Capital Group Review
Jakarta, Indonesia – Indonesia is one of the biggest mining industries in the world, both legal and illegal miners have grown their business especially in coals. The country placed 4th in the top 10 coal producers in 2013. The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan).
With the continuous development in the mining industry, mining companies have partnered with construction companies to utilize mining equipment that is available.
This earthmoving and mining equipment section lists equipment that has been designed primarily to move earth and minerals in large earthmoving and mining projects. Some of this equipment finds it place in other applications, however, and the use of bulldozers and articulated trucks on road and highway projects are just a couple of examples.
One area of surface mining includes giant machines such as drills, electric shovels and giant draglines, some of which have buckets that are capable of moving 160 cubic yards of material in one scoop. Although somewhat smaller than the electric shovel or especially the giant dragline, the mass excavator also fits here, which is basically a large version of the excavator that is used more for mass excavation than for more limited exaction or trenching.
Underground mining equipment is aimed at moving material in a very headroom and space environment. You will notice similarities with some of the surface mining equipment as well as some very specialized pieces developed specifically for the underground mining application. All of these equipment are used with extra warning and precaution.
Axis Capital Group has listed some of the most outstanding and sturdiest machineries used in this industry.
An articulated dump truck has hinge between the cab and the dump box, but it is distinct from semi-trailer trucks in that the cab is permanent fixture, not a separable vehicle. Steering is accomplished via hydraulic rams that pivot the entire cab, rather than rack and pinion steering on the front axle. This vehicle is highly adaptable to rough terrain.
The term bulldozer technically refers only to a shovel-like blade, over the years people have come to associate the term bulldozer to the entire vehicle both blade and crawler tractor combined.
Bulldozers are a powerful tracked piece of equipment and the tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer’s weight over a large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground.
A dragline excavator is a piece of equipment used in civil engineering and surface mining. In civil engineering the smaller types are used as pile driving rigs. The larger types are used in strip-mining operations to move overburden above coal, and for tar-sand mining. Draglines are amongst the largest mobile equipment ever built on land, and weigh in the vicinity of 2000 metric tonnes, though specimens weighing up to 13,000 metric tonnes have also been constructed.
