The SLJ900/32, made by the Beijing Wowjoint Machinery Company, is a 580 ton, 300 foot long and 24 foot wide mega machine that looks more like a train than a crane and acts a lot like a Stretch Armstrong action figure. Instead of using a stationary or crawler crane to lift the girder of a bridge from the ground and drop it into its place, the SLJ900/32 drives the girder onto the previously placed girder, slowly extends its arms to the next support platform, pushes the girder towards the front of the machine and then lowers it into place.

More ‘Tofu Buildings’? String of Collapses Causes Alarm in China

A spate of building collapses in China has left more than two-dozen people dead in recent weeks – and the country’s authorities are sounding the alarm.

Chen Zhenggao, China’s housing minister, this week ordered that old buildings be put under intensified checks and renovated if they are deemed to pose a safety risk.
“Especially with the start of the rainy season, you can’t allow a moment’s delay,” Mr. Chen said during an emergency meeting Wednesday, according to a statement posted by the ministry on its website. He added that cities need to invest more money, bring in private funds for the renovation of shabby structures, and ensure that people take responsibility for safety of buildings.

The move follows a series of startling collapses in several Chinese cities since May 20 – one in the northern city of Tianjin and three in southwest China’s Guizhou province, one of the country’s poorest regions. In the wake of the incidents, China’s online social networks have been flooded with chilling pictures of exposed apartment buildings still standing amidst rubble.
In Guizhou’s provincial capital Guiyang late last month, heavy rainfall resulted in a landslide that caused a nine-story building to collapse, killing 16 people.
A little more than a week later, a seven-story building collapsed in Guizhou’s city of Zunyi, with no fatalities. A nine-story building collapsed days later in the same city, resulting in 4 dead and 3 injured. And on Tuesday, a two-story bathhouse collapsed in Tianjin, leaving six people dead and six injured.
The statement on the ministry’s website did not specify whether China’s central government would be allocating more money or resources to the renovation of old buildings. Many of China’s Internet users also voiced skepticism at the ministry’s orders.
“Here’s an excuse for a new round of city-building,” one user wrote on Weibo, a Chinese equivalent of Twitter, airing a common complaint that local officials in China often pursue needless construction projects in order to line their own pockets with money from developers.
Progress on the standard of construction in China is still wanting, with construction workers also bearing risks.

In December, ten workers were killedduring the construction of a gymnasium in Tsinghua High School in Beijing when a portion of the stadium floor collapsed, burying the workers below.
Structural failures and collapses are the most common cause of death or injury for construction workers, according to China Labour Bulletin, a labor rights group.
Many people have complained about lax construction practices, especially in the smaller cities where towers are often built by unskilled migrant workers. The moniker “tofu buildings” came about after an earthquake in Sichuan 2008 caused school buildings to collapse but left other nearby structures intact. In 2009, a nearly-finished 13-story apartment building in Shanghai tipped over entirely, due to excavations that led to a weakened foundation, according to local press. One worker was killed.
