Hilti's Firestop Silicone Joint Spray CFS-SP SIL is designed for curtain-wall and edge-of-slab applications. One 5-gallon bucket can cover 245 linear ft at a 4 in. gap. Applied via spray or brush, it has a low-slump formula, allowing for use on vertical surfaces. The spray is moisture-resistant after only a few hours of applying.

The W 50 Ri Cold-Milling Machine features Wirtgen's new Level Pro Plus auto-leveling control system. Displacement sensors in the side plates' hydraulic cylinders maintain the preset milling depth. The slimmer design for the W 50 Ri's chassis allows for unobstructed views of the milling edge on the front and sides, and the elevated loading conveyor provides a view of the rear of the machine. The rear conveyor can slew 30� to the left or right, allowing for material to be discharged in crowded jobsite conditions.

The John Deere 350G LC Excavator is powered by a 271-hp Deere PowerTech engine that meets Tier 4 Final emissions standards. According to the manufacturer, the engine's diesel-particulate filter can run 15,000 hours before ash removal is required. The 350G is available with factory-installed sensor mounts, allowing for quicker installation of grade-monitoring sensor packages.

Atlas Copco has introduced three new models of its electric- powered demolition breakers. The B22 weighs 44 lb and is able to deliver 37 ft-lb of impact energy, while the B-25 is able to deliver 55 ft-lb of impact energy at a rate of 1,300 impacts per minute. Both breakers feature brushless motors with built-in power inverters to prevent voltage fluctuations from damaging the breaker. The larger B 30 weighs 70 lb and is able to deliver 74 ft-lb of impact energy. All three of the breakers feature vibration- dampening elements in the handles and casing, allowing for longer periods of continuous use.
