6 Monster Machines That Are Changing Construction

6 monster machines that are changing construction: #1 The ScreedSaver BOSS 240 smoothes out concrete using rollers and blades. It uses GPS to ensure accuracy. #2 The Hunklinger makes bricklaying much quicker. It lays 1,000 bricks of any size and shape per hour! #3 This $100 million monstrous excavator can dig up 240,000 tons of rock a day. The excavator is 310 feet tall and weighs 15,500 tons. It was built to remove coal and excess rock from mines. #4 The BMM300 rolls out brick after brick.  #5 This road-building machine rolls out bricks like a carpet. As the RPS6 Roadprinter rolls backward, gravity brings the bricks flat to rest on the ground. This creates a perfect brick road.  #6 This 6,700-ton monster machine was digging under Seattle for years. "Bertha" the boring machine has a 57.5-foot diameter. The machine was designed to dig a  two-mile-long highway tunnel.
