Watch this mega machine erect a bridge
There’s a lot of moving parts when it comes to the construction of a bridge. Like, how do you build a bridge without the help of a bridge? The easiest way? This SLJ900 machine. It moves in coordinated parts to deftly erect a bridge or viaduct, balancing its weight on the beams before laying out the groundwork. It’s really cool to see it slide across and pop out and Watch how this mega machine constructs a bridge in mountains..
Watch: the 580-ton monster machine constructing bridges in China
Our new Extraordinary engineering video series takes a look at a host of awe-inspiring monster machines and feats of modern engineering from around the world.
Created by Beijing Wow joint Machinery Co, this colossal 580-ton machine is used to construct bridges in China, extending itself between pillars and placing beams along the way.
Future episodes in this series will examine a robotic lifeguard called E.M.I.L.Y as well as the Anton An-225 Mriya, the world’s largest aircraft. Watch how this mega machine constructs a bridge in mountains.
Meet Big Stan: Giant Drill Is the Rock Star of the Southwest
Las Vegas is crowded with performers, but few are as huge as Big Stan. Thought to be the world’s largest truck-mounted drill, Big Stan is flexing its muscles south of the Strip on a $252.5-million, 7-mile-long widening of Interstate 15.
Big Stan’s tall stance originally sprang from deep roots. The 250,000-lb, 93-ft-high boring behemoth was built in 1986 by Anderson Drilling.
Lakeside, Calif., now a part of London-based Keller Group PLC.
The mega-machine, which cost $1.5 million to construct, is named after 6-ft, 3-in.-tall Stan Anderson. Who retired as company president in 2006.
It didn’t take long to realize that what you could buy in the marketplace wasn’t adequate enough for the hard ground in Las Vegas, says Anderson. The bigger the rig, the more work you can get done. The region’s cliche-laden soil often requires heavy drills, trenchers and blasters to break up the sedimentary rock.
With 534,000 ft-lbs of torque and 75,000 lb of crowd pressure, the drill can bore down 200 ft at a rate of nearly 39 rpm. Its augers weigh up to 15,000 lbs. They can drill holes as large as 30 ft in dial and remove up to 5 cu yd of dirt one time. Big Stan is mounted on a 40-ft-long, five-axle truck. It can also fit onto a half- or full-crawler tracked carrier.
