3D Machine Control System is Helping Highway Save Time

As the United States grapples with long-overdue infrastructure repairs – 2009 estimates totaled $2.2 trillion according to the Report Card for America's Infrastructure by the American Society of Civil Engineers – Leica Geosystems in enabling highway contractors win contracts,Impact crusher earn bonuses and save time and money with its Leica PaveSmart 3D machine control system.As the industry leader in St. Louis, Mo., Fred Weber Inc. is earning up to the maximum five percent smoothness bonuses while paving two sections of Highway 364 near St. Charles, Mo., due in large part to the Leica PaveSmart 3D machine control system, which is saving time and money as it eliminates all of the detailed survey labor normally spent for a runway, staking of hubs, setting of blue-tops,It can crush each kind of coarse, Stone crusher, fine cubic material with feeding size not more than 500mm and crushing strength not more than 350MPa and is widely applied to secondary. and the labor to set up stringlines. Under older systems, a concrete paver is controlled by two stringlines set at precise locations on each side of the lane. "When we would pave with a stringline, we were just happy to get 100 percent of our pay," said Nick Hilton, Manager of Concrete Operations for Fred Weber Inc. "Now, with the Leica PaveSmart 3D stringless system, we're not happy unless we're getting a bonus for smoothness."Integrating seamlessly with any GOMACO paver or trimmer, the Leica Geosystems system regulates the steering and grade of the machine with no need to retrofit complex hydraulics. The system guides the trimmer in relation to a digitized 3D model of the highway that runs on a Leica computer on-board the machine."We trim with the Leica Geosystems stringless system [and] we'll trim all the way out into the trackline," said Hilton. "Basically your paver track is running on a smooth ride. And then you take the human error out of it.There's human error in setting stringline and eyeballing it, and we don't have that anymore." Saving money is essential at a time when there's so little of it to update the U.S.infrastructure,Impact crusher has been designed to deal with the Sand making machine, with the side length smaller than 500mm, and anti-pressure strength less than 350Mpa. Impact crusher can be divided into two kinds. which largely dates back 60 – even 80 – years."It's an outrage. Building a world-class transportation system is part of what made us an economic superpower,One of the most interesting facts about Almaty, though, is its association with Uyghur culture. The name derives from the Kazakh word for apple - anma - and is often translated as full of apples." said President Barack Obama, in his speech on jobs before a joint session of Congress on Sept. 8. 2011. "There are private construction companies, all across America, just waiting to get to work."This year, Weber is building a new 10-mile section of Interstate 69 near Newberry, Ind. It's a four-lane divided highway and the contractor is laying 11 inches of new pavement. Early profilographreadings indicate that they earned an average of three percent bonuses on 25 sections of the northbound passing lane.Chefs Kitchen Knives
