Construction Equipment - 1

Construction equipment is a series of blogs in which I would be sharing with you about the equipments which are used in civil engineering works. Most of us dont know about these machines and I hope you will find it interesting to know more about them :) Most of the equipment I'm going to share are the products of Caterpillar also known as CAT. This company is very famous worldwide for its high quality engineering products.

ARTICULATED TRUCKS
An articulated vehicle is a vehicle which has a permanent or semi-permanent pivoting joint in its construction, allowing the vehicle to turn more sharply. There are many kinds of articulated vehicles, from heavy equipment to buses, trams and trains. Steam locomotives were sometimes articulated in that the driving wheels could pivot around turns.
In a broader sense, any vehicle towing a trailer could be described as articulated (the word articulated comes from the Latin articulus : small joint). In the UK, the term "articulated lorry" refers to the combination of a tractor and a semi-trailer, abbreviated to "artic". In the U.S., this is called a semi-trailer truck, "tractor-trailer" or "semi-truck" and would not necessarily be called articulated

CAT 740B

BACKHOE LOADER
A backhoe loader, also called a loader backhoe, digger, or colloquially shortened to backhoe, is a heavy equipment vehicle that consists of a tractor fitted with a shovel/bucket on the front and a small backhoe on the back. Due to its (relatively) small size and versatility, backhoe loaders are very common in urban engineering and small construction projects (such as building a small house, fixing urban roads, etc..).

CAT 450E

COLD PLANER

A cold planer (also known as a pavement planer, pavement recycler, mill or asphalt milling machine or roto-mill) is a construction machine used to remove bituminous pavement or asphalt concrete from roadways, resulting in a somewhat rough, even surface that can be immediately opened to traffic. This is accomplished by bringing a rotating mandrel or "head" into contact with the pavement at an exact depth or slope. The mandrel has hundreds of hardened spikes on its surface, which bite and tear away at the roadway's surface. The surface material that is removed is normally fed by conveyor into a dump truck or semi trailer, but can be left in place or wind rowed to be removed at a later date or recycled. A water spray system provides cooling for the mandrel, as well as dust management.

CAT PM 201

COMPACT TRACK LOADER

A track loader is an engineering vehicle consisting of a tracked chassis with a loader for digging and loading material. The history of track loaders can be defined by three evolutions of their design. Each of these evolutions made the track loader a more viable and versatile tool in the excavation industry. These machines are capable in nearly every task, but master of none. A dozer, excavator, or wheel loader will out perform a track loader under a set of conditions, but the ability of a track loader perform almost every task on a job site is why it remains a part of many companies' fleets.

CAT 299 C

COMPACTOR

A compactor is a machine or mechanism used to reduce the size of waste material or soil through compaction. A trash compactor is often used by homes and businesses to reduce the volume of trash.

Normally powered by hydraulics, compactors take many shapes and sizes. In landfill sites for example, a large bulldozer with spiked wheels called a landfill compactor is used to drive over waste deposited by waste collection vehicles (WCVs).

CAT 836 H

Hope you liked the first set of Construction Equipment, I will soon be adding the construction equipment 2 watch out for more...

India Tower

India Tower (previously known as the Park Hyatt Tower; also known as the Dynamix Balwas Tower or DB Tower) is a supertall skyscraper that is under construction in the city of Mumbai in Maharashtra, India. If completed as proposed, the 125-storey tower would stand 720 m (2,360 ft) high, and would become the world's second-tallest skyscraper, after the Burj Khalifa in Dubai.

The Dynamix Balwas realtor group first proposed the project, under the name of Park Hyatt Tower, in 2008. The Dynamix proposal would have been an 85-storey tower with a height of 301.1 metres (988 ft). The project was subsequently dropped, before being revived and amended in 2010. In January 2010, the Brihanmumbai Municipal Corporation authorised the tower's construction on a site located on Charni Road in Marine Lines, just north of Mumbai's historical district.


the picture shown above is not the real picture its a proposed model picture expected to be completed by 2016. lets hope India completes this building soon enough.

Honjo Masamune : The legendary Japanese Sword

The Honjo Masamune is a ritually forged, ancient Japanese katana with a blade so perfectly balanced and aligned that it splits light, rendering its wielder invisible.

• The sword was forged by Gorō Nyūdō Masamune, and is said to have kept the ruling shogunate in power for hundreds of years by making them invincible in battle.
• Artie claims that the beauty of the sword rests not in its appearance, but in the way was originally forged. He waxes poetic when he says "it was a hammered and folded blade, with millions of layers of steel and a carbon content that's right off the charts. And each layer only atoms – atoms thick."
• It was lost in history and the incomplete blade was rediscovered at a dig site in Okinawa, Japan in 2009.
• The blade is so perfectly forged that its balanced and alignment make it possible for light to split in its path and go around the person holding it, rendering them invisible if the blade is held point up and directly in front of them.

• The idea of bending light was originally proposed by Sir Isaac Newton in 1704 at the end of his treatise on the nature of optics. Little was done with the idea until it was revived in 1911 by Albert Einstein when he wrote "On the Influence of Gravitation on the Propagation of Light" and which he continued to refine and correct into more a elegant theory through 1915 when he completed his general theory of relativity.

• The Honjo Masamune is one of the most controversial and important swords of Japan its current ware about are not known to anybody.

Here are some original pictures of the blade of Honjo Masamune

Undoubtedly the HONJO MASAMUNE is one of the most powerful, important and a legendary sword, such a sword could not be produced again, the skill and art used to produce such a wonderful sword is lost somewhere in history. It is a really amazing sword with amazing properties forged with amazing science, tradition and workmanship...

Causes for HUMAN EXTINCTION

The present state of earth which you see is not constant, our planet is ever changing and always in a danger from unknown forces which can lead to extinction of human species on earth.

Here are some probable reasons why the Human species could be a victim of extinction.

1. WORLD WAR 3 ( NUCLEAR WAR)
The present nuclear weapons that we humans posses for our safety could be the very reason for our extinction, if a world war is to arise then mankind would have to face extinction.

2. INVASION BY COMPUTERS (MACHINES, ARTIFICIAL INTELLIGENCE)

The intelligent computers and robots that we create could someday acquire their own intelligence (artificial intelligence) and try overthrow their own creators by waging a war upon us, the results of such an invasion would be devastating.

3. MASS DEATHS DUE TO PLAGUES, VIRUSES etc.

There have been many incidents and cases in the past where large civilizations have been wiped out by plagues, if such a mutated virus with immense resistance is created it would not be long before we see the end of human race.

4. MEGA DRAUGHTS

Draughts have been a common story since ages, but due to the changes caused by humans to the nature could result in wide range draughts with dire consequences.

Now lets have a look at causes which are beyond our control

5. SUPER VOLCANO

Scientists suggest that there could have been huge super volcanoes in the past which led to the extinction of dinosaurs if such a volcano is to occur now there would be little hope for our survival.

6. MEGA TSUNAMI

A a huge undersea earthquake could unleash a monster tsunami which could drown the entire land surface, there are many such places on earth which could possible cause such havoc.

7. PENDING ICE AGE

Scientists say that the ice age of the past is not a single event but has occurred many times following a particular cycle, We dont exactly know when exactly the next ice age would occur but if it occurs its sure to shun life on earth.

8. BLACK HOLE IN THE SOLAR SYSTEM

The universe is vast with many hidden mysteries, one such mysterious thing is the black hole. If a black hole is supposed to enter our solar system all the planets and sun would be sucked into a pin head sized zone of infinite gravity.

9. METEOR STRIKE

There are many asteroids lurking in space, if an unnoticed asteroid of enough size would hit the earth with just the right velocity, then our fate would just be similar to that of the dinosaurs

Now lets see a situation which we have heard but not sure about it

10. ALIEN INVASION

Suppose an superior species invades our planet..?

We humans such a young species are at the mercy of nature, we should never forget our place and always be thankful for everyday of our life, cause we never know what's gonna happen...

THE RAREST BLOOD GROUP

           
          hh antigen blood group system also known as BOMBAY BLOOD GROUP is the rarest blood group in the world found in only 4 persons per 1000000 persons in the world this makes it the ultra rare blood group in the world.

This blood phenotype was first discovered in Bombay now known as Mumbai by Dr. Y. M. Bhende. The individual with blood group can only give or receive blood only from another person who has a similar blood group, hence as a result any person in need of this rare blood group the transfusion would be highly difficult since such blood is not available in the blood banks.

Bombay phenotype ( Bombay Blood group ) is a rare blood group which shows absence of A,B,H antigens on red cells and presence of anti-A, anti-B and anti-H antibodies in serum.
The rare individuals with Bombay phenotype do not express H substance on their red blood cells and therefore do not bind A or B antigens. Instead, they produce antibodies to H substance (which is present on all red cells except those of hh phenotype) as well as to both A and B antigens and are therefore compatible only with other hh donors.
Individuals with Bombay phenotype blood groups can only be transfused with blood from other Bombay phenotype individuals. Given that this condition is very rare to begin with, any person with this blood group, who needs an urgent blood transfusion, may be simply out of luck, as it would be quite unlikely that any blood bank would have any in stock.
If a Bombay Blood Group recipient is not transfused the blood of a Bombay Blood Group person, it can lead to a haemolytic transfusion reaction, which can be fatal and lead to death.

IF IN CASE YOU FOUND TO HAVE THIS BLOOD GROUP OR FIND ANYBODY WITH THIS ULTRA RARE GROUP MAKE SURE TO DONATE IT, ITS VERY VERY PRECIOUS...

Most Mysterious Places On Earth

Our home planet is full of mysteries and unsolved puzzles, lets see some of the mysterious places whose mysteries still revolve around them

1. BERMUDA TRIANGLE

The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where a number of aircraft and surface vessels allegedly disappeared under mysterious circumstances.


2. EASTER ISLAND

Easter Island is a Polynesian island in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian triangle. A special territory of Chile that was annexed in 1888, Easter Island is famous for its 887 extant monumental statues, called moai, created by the early Rapanui people. It is a World Heritage Site (as determined by UNESCO) with much of the island protected within Rapa Nui National Park.


3. NAZCA LINES

The Nazca Lines are a series of ancient geoglyphs located in the Nazca Desert in southern Peru. They were designated a UNESCO World Heritage Site in 1994. The high, arid plateau stretches more than 80 kilometres (50 mi) between the towns of Nazca andPalpa on the Pampas de Jumana about 400 km south of Lima. Although some local geoglyphs resemble Paracas motifs, scholars believe the Nazca Lines were created by the Nazca culture between 400 and 650 AD. The hundreds of individual figures range in complexity from simple lines to stylized hummingbirds, spiders, monkeys, fish, sharks,orcas, llamas, and lizards.


4. STONEHENGE

Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 2.0 miles (3.2 km) west of Amesbury and 8 miles (13 km) north of Salisbury. One of the most famous sites in the world, Stonehenge is composed of earthworkssurrounding a circular setting of large standing stones. It is at the centre of the most dense complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds.


5. MACHU PICCHU

Machu Picchu ) is a pre-Columbian 15th-century Inca site located 2,430 metres (7,970 ft) above sea level. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cusco and through which theUrubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often referred to as the "Lost City of the Incas", it is perhaps the most familiar icon of the Inca World.
