00:00Il Bagger 293.
00:06Il Bagger 293 è un'buckettura di un'excavator.
00:10È il tipo di un'oceano di un'occhiaio di l'alba.
00:12È un'abstracte tipo di macchina.
00:15È un'occhiaio di un'occhiaio di un'occhiaio di un'occhiaio di un'occhiaio di un'occhiaio di un
00:19'occhiaio.
00:21Il Bagger 293 è in il Guinness Book of World Records
00:26Perché è la grande macchina di un'occhiaio di un'occhiaio di un'occhiaio di un'occhiaio di un'occhiaio.
00:3331,000,000 tardi.
00:34È this iguale a lo 21,000 adulti.
00:37More di due professioni freddovani in lunga.
00:40E è le telle di una buona stessa mette a un'occhiaio di un'occhiaio di un'occhiaio di un
00:44'occhiaio di un'occhiaio.
00:46Il Bagger 303 è un'occhiaio di un'occhiaio più, è l'occhiaio di un'occhiaio.
00:55toni di materiale che si spettano 10 milioni di carri in un secondo.
01:00Il bagger ha 18 massifze bucket, allo lavorando 24-7,
01:04a una ruota 70 in diametre.
01:06Ache bucket può prendere più 15,000 lb di materiale in una scuola.
01:11Questi massifze diggers remove both the earth above buried coal seams,
01:15as well as the coal itself.
01:17Il maschine's principale purpose è a minare for coal.
01:20Unlike most excavatori, though,
01:22il bagger non solo digga e lo truca,
01:24it has its own unique and economical conveyor belt system.
01:28It is far cheaper to convey material than to truck it.
01:33A truck weighs about as much as it carries,
01:37whereas a conveyor weighs a lot less
01:39in comparison to what it can produce and can carry.
01:43The bagger 293 feeds miles of conveyor belts at the Hombok mine.
01:48From there, the coal is loaded onto trains
01:50and shipped to three local power stations.
01:54The bagger 293 is powered by 17,000 kilowatts.
01:59It draws its juice from the very power plants it fuels with coal.
02:03Although this giant extracts enough coal
02:05to provide electric energy to several million homes,
02:08it's run by a very small team.
02:11On this excavator, only five people are working and with these five people and three shifts,
02:18that means 15 people around the clock, we produce this high capacity.
02:22This may be a small crew, but they also have to be fit.
02:26The bagger has more than 2,000 steps and about a half mile of walkways up to a height of
02:31230 feet.
02:33It's not unusual for the team to walk over six miles during a shift.
02:38I think there are not that many.
02:41On to a mine elsewhere.
02:42However, their maximum speed is less than half a mile per hour.
02:46A 13-mile trip can take about three weeks
02:49because of the challenges of crossing roads and avoiding power lines
02:53and the slow speed of the machine.
02:55Still, it's a champion of diggers.
02:57Bucket wheel excavator is, under certain conditions,
03:02the most productive way to extract huge masses of material.
03:09That massive digging comes at a price.
03:12The bagger emits large amounts of very fine dust into the atmosphere.
03:16To dampen down these particles,
03:18workers keep the bagger and the surrounding areas wet.
03:22The coal that's produced presents its own environmental issues, too.
03:26Each ton of coal burned in a power plant
03:29releases one ton of carbon dioxide into the atmosphere.
03:32This contributes to global warming.
03:35Of all the fossil fuels, coal puts out the most carbon dioxide.
03:40The size and the productivity of the 293
03:43make it the king of the diggers in terms of mass.
