Atlas Copco goes green with new range of electric loaders and trucks
4/25/2013
Atlas Copco is launching a range of underground loaders and trucks with electricity as the primary power source. The new range, introduced as The Green Line, includes seven products: two electric underground trucks, four electric underground loaders and a new portable generator.

The underground mining industry is currently facing numerous challenges regarding energy efficiency, carbon emissions and environmental footprints. To help meet these demands, Atlas Copco is now offering a complete "green" range of underground electric trucks and loaders, making the company the world's leading supplier of low-emission underground mining equipment.
"With these new products, we are ready to be part of the global solution for reduced environmental impact" , says David Shellhammer, President, Underground Rock Excavation division at Atlas Copco. "We are especially proud to be the only supplier of underground electric trucks, and I believe this development marks the beginning of a change in the mining industry."
100% diesel emission-free operation
The range of electric underground loaders consists of two new loaders, Electric Scooptram EST1030 and EST14, in addition to the existing Electric Scooptram EST2D and EST3.5 - all 100% diesel emission-free.
"By replacing a 10 tonne diesel loader with the Atlas Copco Electric Scooptram EST1030 you can actually lower your annual emissions equal to 140 cars" , says Erik Svedlund, Product Manager at Atlas Copco. "Besides the fact that the electric loaders don't consume any diesel, they require a minimum of ventilation."
Built on the successful Atlas Copco Scooptram platform and driven with highly efficient electric motors, the new loaders consume less energy, generate less heat and have a lower noise level than diesel loaders. The result is lower running costs, less environmental impact and better working environment.
A new portable generator, Gentrail GT325, simplifies transportation of the electric Scooptram loader, which becomes a one-man-job. With a tramming capacity ranging from 3.6 up to 14 tonnes, there is one size for every application.
Doubled the speed
The new electric underground trucks, Electric Minetruck EMT35 and EMT50, with a load capacity of 35 and 50 tonnes respectively, are about twice as fast as any diesel truck in that capacity range, making them the world's most productive trucks.

Erik Svedlund explains: "Looking at the cost per tonne, using an electric underground truck can almost double the productivity while decreasing the total cost of ownership by up to 50%."
At the same time, the electric trucks reduce energy consumption by up to 70%. High efficiency electric motors drive the axles directly, minimizing transmission losses. Regenerative braking returns the energy to the grid meaning that about 30 % of the energy consumed up the ramp is regenerated going back down.
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner."

"Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
