Milwaukee Electric Tool Corp. Cordless vacuum Three years ago, Milwaukee Electric Tool Corp. juiced up the $12.3-billion tool sector with 28 Volts of cordless power, pushing past a longtime 18-Volt plateau with lithium-ion cells. Refinements to batteries and motors are now enabling new lines of speciality tools. The Brookfield, Wis.-based tool maker is starting to roll out new li-ion tools geared toward smaller, niche tasks, partly in hopes of mitigating effects of a sluggish economy but also to take advantage of the lightweight combination of battery chemistry and “frameless” electric motors. In the mix are a copper-pipe cutter, hacksaw, vacuum

Construction markets are sinking, forcing some contractors that built today’s foreclosed housing tracts to make payroll by selling their iron. But heavy global demand is a bright spot in the U.S. equipment glut. Sukut Construction Inc. Earthmovers go to work inside Nevada gold mine. One builder in Southern California is cashing in on its fleet of “green” machines by renting them out. “We’ve got a lot of equipment, and a lot of it is parked right now,” says Michael Bobeczko, who leads Santa Ana, Calif.-based Sukut Construction Inc.’s marketing department. The contractor, which runs 120 scrapers and other giant earthmovers
Haishan Design Animals inspired dump truck’s “legs.” When Guangzhou, China-based industrial designer Haishan Deng looks for inspiration, he dreams of mammals that carry precious cargo and lizards that morph. Then, he takes those visions and applies them to heavy equipment that not only looks cool but is incredibly versatile. Enter the “Super Tipper Truck,” which Deng recently designed in Munich for Germany-based F.X. Meiller GmbH, a large producer of dump bodies. Deng says he drew on four-legged animals to create a suspended chassis that can squat, stand up and bounce to allow its underbelly to pour off or scoop up
Elastic Sealant: Resists Water and Impacts The Loctite 5510 Adhesive/Sealant is a permanently elastic, primerless formulation that is able to bond and seal a variety of dissimilar substrates, including metals, glass, nylon and plastics. The single-component, oderless adhesive is free of solvents, isocyanates, PVC or silicones. It bonds and seals simultaneously, skinning over relatively quickly and cures to a tack-free surface in 24 hours. Able to fill gaps, resist weather and moisture and withstand ongoing shock and impact, it has many potential uses, including air/water penetration joints, expansion joints, doors, windows, wall penetrations or precast panels. The sealant is available
