The sinister effects of inhaling crystalline silica—which, like asbestos, slowly leads to lung disease and cancer—have been known for years. Only recently have tools that trap the deadly dust become widely available. Slide Show Photo: Tudor Van Hampton / ENR This year’s World of Concrete attracted many new options in dust control. DeWalt now offers cordless portability in dust control “There’s been a drumbeat,” says Matt Gillen, senior scientist at the Washington, D.C.-based National Institute for Occupational Safety and Health. Over the last decade, more suppliers have brought out controls designed to capture dust at the source: the business end

Tension over crane inspection and safety has been playing out in downtown Chicago, where city building officials for nearly a year tried to force a supertall building developer to remove an idle tower crane from a mothballed project.

In 2007, a contractor worked itself into a pickle while building a Midwestern wind farm. There, a Demag CC2600 was being walked from one turbine pad to another. As the 500-ton crawler crane moved down a slight hill, it suddenly tipped forward. The counterweight overcame the upperworks, causing the boom to jackknife and crash to the ground. Photo: WHECO Corp.

Hanging more than 200 ft over a jobsite in down- town Kansas City, Mo., James Hague doesn’t seem to notice the amount of air separating him from the people below. The senior technician fiddles with a dial gauge that measures the amount of play in the crane turntable, the giant gear that rotates the jib. “A bearing could go bad,” he says, suspended from a full-body harness. “And that’s something we want to know before the top falls off.” Slide Show Photo: Tudor Van Hampton / ENR Hague inspects bolts and pins on a J.E.

Terex Corp., Westport, Conn., on Dec. 20 agreed to sell its mining equipment business to South Milwaukee, Wis.-based Bucyrus International Inc. for $1.3 billion in cash. Them firm plans to use some of the proceeds to buy companies “beaten down by the recession,” says Chairman and CEO Ron DeFeo. If the deal closes by the end of next quarter as planned, Bucyrus would provide a wider global footprint in mining, which Terex lacks. Terex would have had to invest $150 million to $200 million “in order to take this business to the next level,” says DeFeo. The move positions Terex
Caterpillar Inc. CEO-elect Douglas R.
