8 Most Impressive Monster Machines

The world’s biggest bucket-wheel excavator 
This machine is 984 feet long, the equivalent of about six Olympic-sized swimming pools in length. It weighs about 91 million pounds, the size of about 380 Blue Whales, which is the largest animal on the planet
Bagger 288 constructed by German company Krupp for Rheinbraun, is the world’s largest land vehicle.
If you want to get the ore, dirt out, or move a mountain, it’s what you need.
Bagger 288 removes 100,000 cubic yards per day.
The Biggest bucket-wheel excavator in the World Cost: $100 million
It Took 5 years to design and manufacture plus another 5 years to assemble
Maximum speed 1/3 mile per hour. 

The biggest` moving man-made machine
Despite how huge and impressive the bagger 288 is, it just would not be fair unless it had a competitor in size. In Lichterfeld, Germany there appears to be another “biggest” moving man-made machine. This colossus of a machine is called the Overburden Conveyor Bridge F60.
Although it weighs less than the bagger 288 (only 11,000 tons instead of 45,500), its length is untouchable-502 meters, or 1,647 feet, (compare 300 meters, or 948 feet for the bagger.) It is also 202 meters, or 663 feet wide. It was built in 1991 by VEB TAKRAF Lauchhammer. After only 13 months in operation, it was shut down for “energy-political” reasons.
To get an idea of how long this machine is in relative terms, if the Empire State Building fell over its length would fall about 200 feet shorter than that of the F60. If the Sears Tower fell over it would be less than 100 feet longer than the F60. Note this comparison includes the lightning rods and antennas of the Empire State Building and the Sears Tower, which if it did not, the F60 would be longer in length than the height of both buildings. Also note that the Sears tower is said to be the tallest building in the world measured from ground to pinnacle point. Below is a picture comparison between the F60 and the Eiffel Tower.

 The worlds largest wheel loader. 

The LeTourneau L-2350 monster wheel loader sports a 53 cubic yard bucket on its massive front arm. For these of you who still can’t picture that, try this: that’s enough space to hold a small fire-truck. LeTourneau builds these to work in some of the largest mines in the world.
It’s powered by a 16-cylinder turbocharged diesel that delivers over 2300 HP to the wheels, which is enough to move it along at about 10-1/2 MPH. That doesn’t sound like much until you consider that it can do it while bench pressing 160,000 pounds 11′ in the air. It also comes in any color you’d like – as long as it’s construction yellow.

The Caterpillar 994

The Cat 994 is a seriously big loader, alas, it’s not the worlds biggest as already stated but at the time, it did employ the use of the worlds largest tires, until the Le Tourneau L-2350 came along and spoilt it !
The cat 994D has a V16 diesel engine that delivers 1500 hp, which is more than adequate for the work that it undertakes. It is equipped with a 4 exhaust stack system and each tailpipe is dedicated to the removal of exhaust from 4 cylinders, and this causes the engine to behave more like four engines operating in tandem.

Giant truck set for sky-high task 

A colossal 28-wheel truck that will help build a major telescope array in the Chilean Andes
The giant vehicle will heave antennas – each weighing 115 tonnes – up a mountainside to the site of the array, a plateau 5,000m above sea level.
The antenna transporter is 10m wide, 20m long and 6m high. It weighs 130 tonnes and has as much power as two Formula 1 engines.
The first of two vehicles has been put through its paces at the firm Scheuerle Fahrzeugfabrik near Stuttgart in Germany.
The vehicles will have to haul their heavy cargo safely from the 2,900m-high Alma base camp, where the antennas are assembled, to the array site, which lies at 5,000m – about half the cruising altitude of a 747.
Because of the low oxygen content of the air at 5,000m, vehicle operators will need to wear portable oxygen canisters. The backrests of the driver seats are shaped to allow the driver to wear his oxygen tank while driving.

- NASA Crawler-transporter

The crawler-transporter is a tracked vehicle used to transport the Saturn V rocket, the Saturn IB rocket during Skylab and Apollo-Soyuz Test Project, and now the Space Shuttle, from NASA’s Vehicle Assembly Building to the Launch pad on a Mobile Launcher Platform. The crawler-transporter, built by the Marion Power Shovel Co. at a cost of $14 million, was once the largest tracked vehicle in the world; it has since been surpassed by the German Bagger 288 excavator.

Big Muskie

“Big Muskie” was once the World’s Largest Earth Moving Machine. What remains today is a monstrous metal bucket, vaguely resembling a robot dog head. The bucket sits on a rise, overlooking the beautiful valley that it once mined and destroyed, which has been renamed “Re-Creation Land.”
Built in 1969, Big Muskie could move 39 million pounds of earth and rock every hour, revealing rich coal seams 100-150 feet down in southeastern Ohio. BM could swing its boom 600 feet, creeping across the landscape on four giant shoes. The immense dragline machine was churning along at full production until 1991, when power demands and o
ther factors convinced the owners to shut down.

Heavy lift vessels

In the early morning of February 16, 2006, the semi-submersible vessel M.V. Kang Sheng Kou of COSCO Shipping, taking advantage of its advanced dynamic positioning system, accomplished a float-over positioning installation of the topside weighing more than
11000 tons in the PM3-CAA oilfield off Thailand Bay.

The World’s First Garbage Powered Garbage Truck

Generating energy from waste may seem like a dream, but one British borough recently announced that they have come as close to closing that loop as anyone in the world. Kirklees Council has adapted their municipal garbage truck to be powered by the very trash that it collects!

The van is a Smith Edison Transit truck that goes around collecting rubbish from 25 bins that are located around the city. This rubbish is then taken to the Energy from Waste power station that generates electricity that powers the truck that runs around the city collecting the trash – and so the circle is completed.

The Smith Edison van has been fitted with a 40kWh lithium-ion battery that provides the truck with a maximum speed of 50mph and a range of 100 miles. Not all the trash is used to power this vehicle though – the trash is also used to power the town. The Electricity from Waste power station provides around 10 megawatts into the national grid.

Nuclear powered icebreaker

A nuclear powered icebreaker is a purpose-built ship for use in waters continuously covered with ice. Icebreakers are ships capable of cruising on ice-covered water by breaking through the ice with their strong, heavy, steel bows. Nuclear powered icebreakers are far more powerful than their diesel powered counterparts, and have been constructed by Russia primarily to aid shipping in the frozen Arctic waterways in the north of Siberia.

During the winter, the ice along the northern seaways varies in thickness from 1.2 to 2.0 metres (3.9 to 6.5 feet). The ice in central parts of the Arctic Ocean is on average 2.5 metres (8.2 ft) thick. Nuclear-powered icebreakers can force through this ice at speeds up to 10 knots (19 km/h). In ice-free waters the maximum speed of the nuclear-powered icebreakers is as much as 21 knots (35 km/h).

Uses of nuclear-powered icebreakers

The nuclear ice breakers of the Arktika (Arctic) design are used to force through the ice for the benefit of cargo ships and other vessels along the northern seaway. The northern seaway comprises the eastern part of the Barents Sea, the Petchora Sea, the Kara Sea, the Laptev Sea and the Eastern Siberia Sea to the Bering Strait. Important ports on the northern seaway are, among others, Dikson, Tiksi, and Pevek.

Two nuclear-powered icebreakers, NS Vaigach and NS Taimyr, have been built for shallow waters and are usually used on the river Yenisei to Dikson, where they break through the ice followed by cargo ships with lumber from Igarka and cargo ships with ore and metals from the Norilsk Company’s port Dudinka. These nuclear powered icebreakers can also be used as fireboats.

The icebreakers have also been used for a number of scientific expeditions in the Arctic. On August 17, 1977, the NS Arktika was the first surface vessel in the world to reach the North Pole. Since 1989, some icebreakers have been used for Arctic tourism cruises.

Russian nuclear icebreakers
In all, ten civilian nuclear powered vessels have been built in Russia. Nine of these are icebreakers, and one is a container ship with an ice-breaking bow. All nuclear-powered icebreakers of the NS Arktika design have been built at the Admiralty Shipyard in St. Petersburg. The NS Vaigach and NS Taimyr were built at the Helsinki New Shipyard in Finland and then brought to Russia for installation of the reactors and steam propulsion systems.

Russian Nuclear Icebreakers: to the North Pole!

Odyssey in the Arctic with Russian Icebreaker Fleet

The nuclear-powered icebreakers served as a symbol of Soviet technological power for many decades. Today this fleet is used to aid ship navigation in the seas north of Siberia – and for elite tourism, which helps to pay the bills. 

The most powerful of all icebreakers “50 years of Victory” (one of six “Arktika” class) has two nuclear reactors and is capable of reaching North Pole in a couple of days.

Svetlana Bogdanova has recently returned from a very special trip on board of icebreaker “Vaigach” and provided us with these unique pictures. Thanks to her exclusive permission (and collection of photos by seamen of the Murmansk Sea Shipping Company) we can now have a glimpse of what it means to follow along the caravan of ships in the northern seas, led by a colossal nuclear-powered vessel.

Svetlana says: “A nuclear icebreaker almost feels alive, like a huge proud creature with a benevolent and dependable character. See it moving in the dark of night, projecting a powerful light ahead, making the snow sparkle in a misty path, feel it tremble under your feet… Its sheer immensity is inspiring, making one think of heroic exploration of unknown lands, the stuff that kids should be dreaming about”

Unexpected Rescue:
This truck got in trouble on treacherous ice, so a professional team quickly comes up with a plan:

The journey resumes:

Breaking the way for a caravan of ships:

Arriving into Dixon: a small town of about a thousand people -

Its population lives in the Arctic wasteland, enduring the most extreme climate. A significant part of Dixon has become a ghost town during Soviet years – and a series of ghastly buildings line up to haunt the endless night:

It’s easy to start imagining vampires, but the buildings are long abandoned – though one has to wonder about what looks like a cannon nearby:

Here are Some of the Giants of the Arctic Fleet:

“Lenin” was the first Russian nuclear icebreaker, built in 1957. It looked imposing, but suffered two nuclear accidents while in operation till 1989, and now is being converted into a museum ship. Another milestone: “Arktika” became the first surface ship ever to reach the North Pole in 1977.

“50 Years of Victory” – is the largest, most powerful icebreaker ever constructed.

This lid covers a nuclear reactor:

Nuclear reactor room:

117 meters in length, the “50 Years of Victory” has TWO nuclear reactors, develops around 500,000 horse power, and its huge steel ice belt 5 meters wide can easily break through ice up to 2.5 meters (9.2 feet) thick. (The “victory” in its name is the Russian people’s victory over the Nazis in 1945)

And by the way, in case you’re thinking that no ice can ever stop such behemoths, let me remind you that the nuclear icebreaker “Soviet Union” was trapped in ice for three
days in 1998 (which is nothing compared to Mother Russia trapped in communism for 70 years)

Here is that “Soviet Union” ship -

Other Nuclear Icebreakers are described:

1 Lenin (nuclear icebreaker)

NS Lenin is a Soviet icebreaker launched in 1957, and is both the world’s first nuclear powered surface ship and the first nuclear powered civilian vessel. Lenin was put into operation in 1959 and officially decommissioned in 1989.

2 Arktika (icebreaker)

The NS Arktika is a nuclear powered icebreaker of the Soviet (now Russian) Arktika class. In service since 1975, she was the first surface ship to reach the North Pole, on August 17, 1977.

The Arktika was retired for several years, but was repaired in the late 1990s. She is operational as of 2007.

On April 9, 2007 a fire broke out on the Arktika. The fire devastated three cabins and knocked out an electricity-distribution panel. The nuclear reactor was not damaged. There were no injuries. The icebreaker was in the Kara Sea when the blaze erupted, and was sent to Murmansk.The ship was officially taken out of service in October 2008

3 Sevmorput

Sevmorput (russian : ??????????) is a nuclear-powered merchant vessel constructed in the Kerch (Ukraine) at Zaliv plant. It was named for “Sevmorput”, the home base of the Soviet Union’s nuclear fleet dockyard. The name is a shortened form for Severnii Morskoi Put (Northern Sea Passage).

Construction of the vessel was undertaken in 1983, but its launch did not take place until 1988.

It is classified as a Lash-Carrier, hauling lighters and container cargo.

Earlier owned and operated by the Murmansk Shipping Company, Sevmorput was transferred to Rosatom in August 2008. She serves along the Northeast Passage for which she is equipped with an ice-breaking bow.

As of August 2007 Sevmorput is being converted into the world’s first nuclear-powered oil drilling vessel. The conversion is expected to take only 18 months.

Sevmorput is capable of breaking ice up to 1 meter thick (1.2 meters according to this source)

4 Taymyr (nuclear icebreaker)

Taymyr (sometimes spelled Taimyr) is a shallow-draft nuclear powered icebreaker, and the first of four similar vessels. She was built in 1989 for the Soviet Union in Helsinki, at the Finnish shipyard Wartsila, by order of the Murmansk Shipping Co.

The Taymyr was delivered to Russia for the installation of the reactor system. It has a nuclear-turbo-electric reactor giving up to 50,000 hp. This shallow-draft icebreaker is used mainly for clearing rivers, including their mouths and estuaries of ice and opening channels in order to make winter navigation possible.

This icebreaker and its sister ship Vaygach belong to a type known as Taymyr-class River Icebreakers.

The Call sign of Taymyr is UEMM.

5 Vaygach (nuclear icebreaker)

he Vaygach (sometimes spelled Vaigach) is a shallow-draft nuclear powered icebreaker. She was built in 1989 for the Soviet Union in Helsinki, at the Finnish shipyard Wartsila, by order of the Murmansk Shipping Co.

The Vaygach was delivered to Russia for the installation of the reactor system. It has a nuclear-turbo-electric reactor giving up to 50,000 hp. This shallow-draft icebreaker is used mainly for clearing rivers, including their mouths and estuaries of ice and opening channels in order to make winter navigation possible.

This icebreaker and its sister ship Taymyr belong to a type known as Taymyr-class River Icebreakers.

6 Yamal (icebreaker)

The NS Yamal (Russian: ???´?) is a Russian Arktika class nuclear powered icebreaker operated by the Murmansk Shipping Company. It is named after the Yamal Peninsula in Northwest Siberia; the name means End of the Land in the Nenets language.

Laid down in Leningrad in 1986, and launched in October 1992, after the end of communism in Russia, she never filled her designed role of keeping shipping lanes open. She has always carried passengers on arctic excursions. Yamal took an excursion to the North Pole to celebrate the Millennium. Yamal is the 12th surface ship ever to reach the north pole.

7 NS 50 Years Since Victory

NS 50 Years Since Victory or 50 Years Anniversary of Victory (Russian: 50 ??? ??????, transliterated as 50 Let Pobedy) is a Russian Arktika class nuclear powered icebreaker, the largest in the world as of 2007.

Construction on project no. 10521 started on October 4, 1989 at the Baltic Works in Leningrad (currently Saint Petersburg), USSR. Originally the ship was named NS Ural. Work was halted in 1994 for lack of funds, so that the real 50 Years Anniversary of Victory Day in 1995 found the ship in an abandoned state. Construction was restarted in 2003.

On 30 November 2004, a fire broke out in ship. All workers aboard the vessel had to be evacuated while the fire crews battled the fire for some 20 hours before getting it under control. One worker was sent to hospital. There was no threat of radioactive contamination as the nuclear reactor had no fuel inside.

She was finally completed in the beginning of 2007, after the 60th Anniversary. The icebreaker sailed into the Gulf of Finland for two weeks of sea trials on February 1, 2007.

Upon completing sea trials, the icebreaker returned to St-Petersburg Baltic shipyard and started preparations for her maiden voyage to Murmansk. The new ship showed superior characteristics for an icebreaker, such as exceptional maneuverability and a top speed of 21.4 knots (39.6 km/h).

She arrived at her homeport Murmansk on April 11, 2007.
