Types Of Construction Equipment And Their Uses

By Lucy Bartlett

Construction equipment range from the very heavy equipment to the portable and mobile lighter equipment, some of them with a precise description of their functions are detailed below.

Engineering equipment with a front bucket/shovel and a small backhoe in the rear combined with a tractor is known as backhoe loader. It is mostly used in small construction sites and in urban engineering such as fixing city roads.

A crawler, which is very powerful and attached with a blade, is called a bulldozer. Even though any heavy engineering vehicle is known as bulldozer, it is actually a tractor with a dozer blade.

Combat engineering vehicles are used for engineering work in the battlefield and for transporting sappers. They are mostly armoured vehicles.

A compact excavator is a wheeled or tracked vehicle with a backfill blade and swing boom. It is also known as mini excavator. The functions and movements of the machines are carried out by transferring hydraulic fluid. This makes a compact hydraulic excavator different from other construction equipment.

To compact gravel, dirt, asphalt and concrete in construction work and road laying a road roller which is also known as roller-compactor would be used.

A motorized cultivator with a rotating blade to work in the soil is known as rotary tiller. They are either drawn behind a tractor or self-propelled.

A crane is a derrick or tower equipped with pulleys and cables for lowering and lifting materials. The cranes used in construction industry are mostly temporary structures.

Dragline excavation systems are heavy equipment mostly used in surface mining and civil engineering. The smaller type of dragline excavator is used for port and road construction. The larger type dragline excavator is used in strip-mining operations for coal extraction.

In the building industry, to make foundations, a drilling machine is used. It is also used in oil wells and water wells.

An excavator commonly known as a digger is an engineering vehicle, with a cab mounted on a rotating platform or pivot, and a backhoe on top of an undercarriage with wheels or tracks.

In untamed regions which are being reclaimed for construction, a feller buncher, a machine having an attachment, which fells trees, is used.

A forklift, lift truck or forklift truck is an industrial truck used to pick up and transport heavy material using steel forks under the material to be lifted. The most common usage of a forklift is to move materials stored on pallets.

A loader also known as a bucket loader, front-end loader, scoop loader, shovel, or front loader is a type of tractor using buckets, which can be tilted to lift and move material.

A paver is used to spread asphalt on roadways.

Smoke from massive warehouse fire in Buffalo, New York USA can be seen 40 miles away

Monday, May 14, 2007

Buffalo, New York — A massive warehouse complex of at least 5 buildings caught on fire in Buffalo, New York on 111 Tonawanda Street, sending a plume of thick, jet black colored smoke into the air that could be seen as far away as 40 miles.

As of 6:40 a.m., the fire was under control, and firefighters were attempting to stop it from spreading, but could not get to the center of the fire because of severe amounts of debris. Later in the morning, the fire was extinguished.

“The fire is mostly under debris at this point. It’s under control, but it’s under some debris. We really can’t get to it. We’re just going to have to keep on pouring water on it so it doesn’t spread,” said Thomas Ashe, the fire chief for the North Buffalo based fire division who also added that at one point, at least 125 firefighters were on the scene battling the blaze. One suffered minor injures and was able to take himself to the hospital to seek medical attention.

Shortly after 8:00 p.m. as many as 3 explosions rocked the warehouse sending large mushroom clouds of thick black smoke into the air. After the third explosion, heat could be felt more than 100 feet away. The fire started in the front, one story building then quickly spread to three others, but fire fighters managed to stop the flames from spreading onto the 3 story building all the way at the back.

According to a Buffalo Police officer, who wished not to be named, the fire began at about 7:00 p.m. [Eastern time], starting as a one alarm fire. By 8:00 p.m., three fire companies were on the scene battling the blaze. Police also say that a smaller fire was reported in the same building on Saturday night, which caused little damage.

At the start of the fire, traffic was backed up nearly 4 miles on the 198 expressway going west toward the 190 Interstate and police had to shut down the Tonawanda street exit because the road is too close to the fire.

At one point, traffic on the 198 was moving so slow, at least a dozen people were seen getting out of their cars and walking down the expressway to watch the fire. That prompted as many as 10 police cars to be dispatched to the scene to force individuals back into their cars and close off one of the 2 lanes on the westbound side.

One woman, who wished not to be named as she is close to the owner of the warehouse, said the building is filled with “classic cars, forklifts, and money” and that owner “does not have insurance” coverage on the property. The building is not considered abandoned, but firefighters said that it is vacant.

Officials in Fort Erie, Ontario were also swamped with calls to fire departments when the wind blew the smoke over the Niagra River and into Canada.

It is not known what caused the fire, but a car is suspected to have caught on fire and there are reports from police and hazmat crews, that there were also large barrels of diesel fuel being stored in one building. Firefighters say the cause of the blaze is being treated as “suspicious.” The ATF is investigating the fire and will bring dogs in to search the debris.

Manitoba’s flood creating hazardous conditions

Tuesday, April 14, 2009

The Red River at Winnipeg is almost clear of ice blocks and ice jamming, however there are still dangers from the Red River flood.

Ice blocks which were as high as two storey buildings were ripping out trees, fences and railway ties. “You’ll see huge pans of ice standing vertical, up to 20 feet (6.1 m) high,” said Steve Topping, an official with the provincial Water Stewardship Department. “Ice was shoved up on the shore and took out trees with a very devastating effect. It has changed people’s view of the river.”

“It is incredible, the force. One piece of ice pushed out of the river about 20 feet. You watch the force push this up right in front of your eyes,” said Dean North, of the Selkirk Golf and Country Club.

Royal Canadian Mounted Police are ticketing sight seers who are driving through road closure signs and approaching excavators, cranes and crews breaking up the ice. Vehicles, people, boats, and kayaks are getting in the way.

An eight year old boy is in critical condition after slipping on a culvert Thursday. He was pulled underwater by the speed of the flowing water and remained under for about five to ten minutes until adults could rescue him. The air ambulance supplied by Alberta’s STARS (Shock Trauma Air Rescue Society) remains in the city of Winnipeg, Manitoba.

“This is not a spectator sport. It’s not about getting the best pictures for the family albums. I know floods are seen as a bit of an event, but some of the instances I’m hearing about, people should give their head a shake, they really should,” said Steve Ashton Manitoba Emergency Measures Minister, “Those who fall into the river or get into trouble in another way would be not only endangering themselves but the emergency response crews trying to rescue them. I don’t want to see a situation … where we’re trying our darndest to prevent flooding and save lives and somebody [who] decides to go have a white-water experience ends up killing themselves.”

Early Easter Sunday morning floodwater reached the rural municipalities of St. Andrews and St. Clements north of Winnipeg. Residents were sent an evacuation advisory Good Friday, however some residents remained. Rescue efforts commenced Saturday night to find those stranded and unable to leave as their vehicles cannot travel in the swollen overland floodwaters. Some people were rescued from roof tops as entire houses were swept off of their foundations by the large ice blocks hurtling down the river.

Highways in the area remain closed. Neil Gobelle, of Manitoba Infrastructure and Transportation said to “definitely continue to watch the Red River Valley and north of the city up in the Selkirk area. Things are changing quite a bit, quite quickly, so we’ll keep an eye on those areas.”

As of Easter Sunday, Winnipeg is expected to be ice free on the Red River. The River rose 4 feet (1.2 m) in the course of 24 hours. Rain is in the forecast and the higher temperatures of 17 °C (62.6 °F) will cause melting of snow and ice.

A weather system caused by La Niña is being watched by the United States National Weather Service and its potential effects between April 16-18 for residents along the Red River Valley. “We want people to be aware there is a very real possibility of the river going higher than what is out there,” said Mark Ewens, data manager at the NWS, “To have spring floods like this back-to-back is just an unfortunate series of events that have come along to plague us this spring. We’re wanting people to understand that this is a potentially serious problem.”

Obama lessens US ban on offshore drilling

Thursday, April 1, 2010

US President Barack Obama has announced that he will ease the country’s ban on offshore oil drilling, which has been in place since the 1980s.

According to the plan, offshore drilling would now be allowed in parts of the Atlantic, from Delaware down to 125 miles beyond the shoreline of Florida, in the eastern Gulf of Mexico.

The move, however, does have some restrictions; drilling further northeast or along the West Coast is still prohibited. Contracts in Bristol Bay, Alaska were also suggested, but were scrapped due to environmental concerns.

The president remarked that he decided the move was needed to lessen the country’s need for additional energy, adding that he had studied the issue for over a year. “This is not a decision that I’ve made lightly,” he said.

“We’re announcing the expansion of offshore oil and gas exploration but in ways that balance the need to harness domestic energy resources and the need to protect America’s natural resources,” Obama continued, speaking at Andrews Air Force Base in Maryland. “My administration will consider potential new areas for development in the mid and south Atlantic and the Gulf of Mexico.”

“Drilling alone can’t come close to meeting our long-term energy needs, and for the sake of our planet and our energy independence, we need to begin the transition to cleaner fuels now. I know that we can come together to pass comprehensive energy and climate legislation that’s going to foster new energy — new industries, create millions of new jobs, protect our planet, and help us become more energy independent.”

Obama said that the plan was partially intended to garner support from Republicans in Congress for a climate-change bill to lower greenhouse gas emissions, which has been languishing for months due to lack of support from Republicans.

Some environmental groups, however, condemned Obama’s move. Phil Radford, who is with the Greenpeace group, said that “[e]xpanding offshore drilling in areas that have been protected for decades threatens our oceans and the coastal communities that depend on them with devastating oil spills, more pollution and climate change.” Greenpeace also said that lifting the ban fuelled the US’ “addiction to oil”.

Republican leader for the House of Representatives John Boehner, meanwhile, said he agreed with lifting the ban in the Atlantic, but remarked that it “makes no sense” not to have lifted it in other areas as well. “Opening up areas off the Virginia coast to offshore production is a positive step, but keeping much of the Pacific Coast and Alaska, as well as the most promising resources off the Gulf of Mexico, under lock and key makes no sense at a time when gasoline prices are rising and Americans are asking ‘Where are the jobs?'”, he said.

“Today’s announcement is a step in the right direction, but a small one that leaves enormous amounts of American energy off limits,” said the Senate Minority leader, Republican Mitch McConnell.

According to the US Minerals Management Service, the eastern Gulf of Mexico and parts of the Atlantic south and east of the continent could contain up to 5.8 billion barrels of oil and 40.5 trillion cubic feet of gas. The West Coast, meanwhile, which remains off limits for drilling, contains 10.5 billion barrels of oil with 18 trillion cubic feet of gas.

Asbestos controversy aboard Scientology ship Freewinds

Friday, May 16, 2008

Controversy has arisen over the reported presence of blue asbestos on the MV Freewinds, a cruise ship owned by the Church of Scientology. According to the Saint Martin newspaper The Daily Herald and the shipping news journal Lloyd’s List, the Freewinds was sealed in April and local public health officials on the Caribbean island of Curaçao where the ship is docked began an investigation into the presence of asbestos dust on the ship. Former Scientologist Lawrence Woodcraft supervised work on the ship in 1987, and attested to the presence of blue asbestos on the Freewinds in an affidavit posted to the Internet in 2001. Woodcraft, a licensed architect by profession, gave a statement to Wikinews and commented on the recent events.

According to The Daily Herald, the Freewinds was in the process of being renovated by the Curaçao Drydock Company. The article states that samples taken from paneling in the ship were sent to the Netherlands, where an analysis revealed that they “contained significant levels of blue asbestos”. An employee of the Curaçao Drydock Company told Radar Online in an April 30 article that the Freewinds has been docked and sealed, and confirmed that an article about asbestos ran in the local paper.

Lloyd’s List reported that work on the interior of the Freewinds was suspended on April 27 after health inspectors found traces of blue asbestos on the ship. According to Lloyd’s List, Frank Esser, Curaçao Drydock Company’s interim director, joined Curaçao’s head of the department of labor affairs Christiene van der Biezen along with the head of the local health department Tico Ras and two inspectors in an April 25 inspection of the ship. “We are sending someone so that they can tell us what happened, where it came from, since when it has been there,” said Panama Maritime Authority’s director of merchant marine Alfonso Castillero in a statement to Lloyd’s List.

The Church of Scientology purchased the ship, then known as the Bohème, in 1987, through an organization called Flag Ship Trust. After being renovated and refitted, it was put into service in June 1988. The ship is used by the Church of Scientology for advanced Scientology training in “Operating Thetan” levels, as well as for spiritual retreats for its members. Curaçao has been the ship’s homeport since it was purchased by the Church of Scientology.

According to his 2001 statement, Lawrence Woodcraft had been an architect in London, England since 1975, and joined Scientology’s elite “Sea Organization” (Sea Org) in 1986. He wrote that he was asked by the Sea Org to work on the Freewinds in 1987, and during his work on the ship “noticed a powdery blue fibrous substance approximately 1 ½” thick between the paint and the steel wall,” which he believed to be asbestos. He also discovered what he thought was blue asbestos in other parts of the ship, and reported his findings to Church of Scientology executives. Woodcraft discussed his experiences in a 2001 interview published online by the Lisa McPherson Trust, a now-defunct organization which was critical of the Church of Scientology.

The Freewinds regularly inspects the air quality on board and always meets or exceeds US standards.

Church of Scientology spokeswoman Karin Pouw responded to Radar Online about the asbestos reports, in an email published in an article in Radar on May 1. “The Freewinds regularly inspects the air quality on board and always meets or exceeds US standards,” said Pouw. She stated that two inspections performed in April “confirmed that the air quality is safe,” and asserted that the inspections revealed the Freewinds satisfies standards set by the United States Occupational Safety and Health Administration and the U.S. Clean Air Act.

Pouw told Radar that “The Freewinds will be completing its refit on schedule.” The Church of Scientology-affiliated organization Citizens Commission on Human Rights (CCHR) had been planning a cruise aboard the Freewinds scheduled for May 8, but according to Radar an individual who called the booking number for the cruise received a message that the cruise had been delayed due to ongoing work on the ship. Citing an article in the Netherlands Antilles newspaper Amigoe, Radar reported on May 6 that a team from the United States and supervised by an independent bureau from the Netherlands traveled to Curaçao in order to remove asbestos from the Freewinds.

…if the Church of Scientology claims to have removed the blue asbestos, I just don’t see how, it’s everywhere. You would first have to remove all the pipes, plumbing, a/c ducts, electrical wiring etc. etc. just a maze of stuff.

“I stand by everything I wrote in my 2001 affidavit,” said Lawrence Woodcraft in an exclusive statement given to Wikinews. Woodcraft went on to state: “I would also comment that if the Church of Scientology claims to have removed the blue asbestos, I just don’t see how, it’s everywhere. You would first have to remove all the pipes, plumbing, a/c ducts, electrical wiring etc. etc. just a maze of stuff. Also panelling as well, basically strip the ship back to a steel hull. Also blue asbestos is sprayed onto the outer walls and then covered in paint. It’s in every nook and cranny.”

Many Scientologist celebrities have spent time aboard the Freewinds, including Tom Cruise, Katie Holmes, John Travolta, Kelly Preston, Chick Corea, Lisa Marie Presley, Catherine Bell, Kate Ceberano, and Juliette Lewis. Now magazine reported that Tom Cruise has been urged to seek medical attention regarding potential asbestos exposure, however a representative for Cruise stated he has “absolutely no knowledge” of the recent asbestos controversy. Cruise, Holmes, Travolta and Preston have celebrated birthdays and other events on the Freewinds.

There is not now and never has been a situation of asbestos exposure on the Freewinds.

In a May 15 statement to the United Kingdom daily newspaper Metro, a representative for the Church of Scientology said that “There is not now and never has been a situation of asbestos exposure on the Freewinds.” The Asbestos and Mesothelioma Center notes that agencies have recommended anyone who has spent time on the Freewinds consult with their physician to determine if possible asbestos exposure may have affected their health.

Raw blue asbestos is the most hazardous form of asbestos, and has been banned in the United Kingdom since 1970. Blue asbestos fibers are very narrow and thus easily inhaled, and are a major cause of mesothelioma. Mesothelioma is a form of cancer which can develop in the lining of the lungs and chest cavity, the lining of the abdominal cavity, or the pericardium sac surrounding the heart. The cancer is incurable, and can manifest over 40 years after the initial exposure to asbestos.

“This is the most dangerous type of asbestos because the fibres are smaller than the white asbestos and can penetrate the lung more easily,” said toxicologist Dr. Chris Coggins in a statement published in OK! Magazine. Dr. Coggins went on to note that “Once diagnosed with mesothelioma, the victim has six months to a year to live. It gradually reduces lung function until the victim is no longer able to breathe and dies.”

The Shocking Truth About Video Game Testing Jobs

By Mike Chen

Picture this: you and some buddies kicking back and spending the day playing the latest video games – before they are even released to the public! Sound good? Now imagine you’re getting paid too; you’re one of the lucky people doing video game testing jobs from home!

On the surface of course, working from home testing the latest video games probably seems like the ultimate career opportunity for young gamers. Having access to the hottest upcoming titles, the programmers and artists and being a part of the team bringing game to market is exciting and rewarding. But this type of opportunity requires far more than good hand/eye coordination!

Testing is part of an overall quality assurance process that requires an eye for detail, excellent communication skills and an enormous amount of patience. Playing a video game over and over or repeating a series of actions to reach a specific point in a game 30 or 40 times is tedious and can cause burnout very quickly. It’s literally not all fun and games!

[youtube]http://www.youtube.com/watch?v=GzbFgAuO8Vw[/youtube]

When you’re actually sitting there playing a video game, testing specific features and functions, you also have to follow a process for communicating bugs or other errors. For example, when you identify a problem with the game, you first check a log to determine whether or not it’s already been reported. If not, you need to carefully document the error, often writing several pages of a description of what occurred and of course instructions for replicating it.

Once the bug has been corrected, regression testing kicks in – you go back and test again and again to ensure that the problem is indeed fixed. You also have to re-test the video game to ensure that the changes made to the original bug did not in turn create any new problems. This is where the process gets especially boring and repetitive. Remember, you’re not doing this to win the game!

You should also be aware that video game testing begins around the time the game is approximately 75% complete. Most often this means that there will be gaps in game sequences, codes that don’t work, audio tracks may not be available and so on. So as part of your work to test the game, you’ve got to keep a clear division between what is incomplete and what is really a bug. On the upside though, if you are one of those people who tends to easily notice the bugs in games, you’ll be happy to know that some employers even offer bonuses for the number of bugs a tester finds.

Really the truth is that every job has its downside and, despite all of the not-so-fun parts of testing video games, the testers do have very cool jobs. After all, they do get to work from the comfort of their home, which often means setting their own hours. Playing video games for different platforms or game consoles exposes them to the latest gaming technology well ahead of their friends. If you’re an enthusiastic gamer, finding good video game testing jobs from home could become a fantasy career for you!

Ahmadinejad sends letter to George W. Bush

Tuesday, May 9, 2006 For the first time in three decades, direct and at least partially public diplomatic communication will commence between the United States (US) and Iran. Iranian government spokesman Gholam-Hossein Elham said that Iranian president Mahmoud Ahmadinejad has sent a letter to the U.S. president George W. Bush proposing “new solutions for getting out of international problems and the current fragile situation of the world”.

Mr Gholam-Hossein Elham did not say whether the letter mentioned the nuclear dispute, one of the diplomatic problems currently straining relations between Iran and the USA. This information arrived one day after the Iranian parliament announced that it might retract from the Nuclear Non-Proliferation Treaty (NPT) if Western pressure over its programme was to increase.

Differing reports have been made as to whether or not the letter will be made public, and if so, when. In its online report of 8 May 2006, 09:25 GMT, the BBC quoted Iranian Foreign Ministry spokesman Hamid Reza Asefi as saying that the contents of the letter would be made public once Bush had received it. The updated version of the report of 8 May 2006, 14:52 GMT, quotes Asefi as saying that the contents would be made public “at the right time”. An ABC report quoted Gholam-Hossein Elham as saying “it is not an open letter.”

Iran’s foreign affairs minister, Manouchehr Mottaki, delivered the letter to the United States’ interests section in the Swiss embassy in Tehran on Monday. The United States has not held diplomatic relations with Iran since the 1979 Iranian hostage crisis.

U.S. Secretary of State Condoleezza Rice said “this letter isn’t it. This letter is not the place that one would find an opening to engage on the nuclear issue or anything of the sort.”

“It isn’t addressing the issues that we’re dealing with in a concrete way,” she added.

John R. Bolton, U.S. Ambassador to the United Nations, also read the letter, saying, “I think it is typical of Iran that when major decisions are about to be taken … that they have tried to throw sand in the eyes of the proponents of the action. That’s what this may be.”

The letter has since been put on an official Iranian website, and on Tuesday, Ahmadinejad said “the letter to US President George Bush carries the Iranian nation’s views and comments on international issues as well as suggestions for resolving the many problems facing humanity.”

Chinese authorities say they are preparing to launch a crackdown on melamine-laced milk after the scandal over tainted products, which made hundreds of thousands of children ill two years ago and damaged China’s brand reputation overseas, resurfaced.

China has dispatched inspectors to sixteen provinces to urge local governments to thoroughly investigate cases concerning food safety.

The decision comes after milk products tainted with the industrial chemical melamine were removed from sale in Shanghai and the provinces of Shaanxi, Shandong, Liaoning and Hebei, the state-run Xinhua News Agency said.
