A bridge needs to be built, so time to bust out the cranes, right? Not so fast, a Chinese company has built a machine that has a creative way of setting girders into place.
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.

Multiple buildings imploded at the same time with multiple different camera views? Sounds like the making of a great demolition video.
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
As the US is experiencing our own natural disaster, by way of Hurricane Florence, China is being hit badly by a Typhoon Mangkhut. According to Independent, the storm has caused a crane, which was being used on a 22-story housing development, to crumble. That collapse was caught on camera by neighbors.
There have been a few devastating structural collapses across America and the world this year. In March, an under construction pedestrian bridge collapsed in Florida, killing 6. In Colombia, ten workers were killed when a large section of a bridge being built collapsed. Both of those tragedies happened while the structures were still being built, but a recent collapse in Texas has a bit of a different story.
If you’re a general contractor in the Davie, Florida area, I have an idea why one of your deliveries might have been late last week.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
