December 2017 | EquipmentWorld.com 16 marketplace | continued Grinding twice as fast Chicago Pneumatic's new CP3330 and CP3340 vertical grinders can remove material twice as fast as similar tools on the market, the company says. The CP3330 comes with a 3.7-horsepower motor, while the CP3340's motor packs 4.5 horsepower. The com- pany also added safety features, including automatic shut-off to prevent the abrasive from over-speeding and causing accidents; a 1-inch-thick protective wheel guard; and a safety lever that can be easily used while wearing gloves. No trailer required Gradall has designed its newest version of the XL 4100 hydraulic exca- vator to be more fuel efficient, while still achieving speeds up to 60 mph on the road. The XL 4100 V excavator is powered by a 153-horsepower, Tier 4 Final Volvo Penta diesel engine, which achieves a 5 percent improve- ment in fuel efficiency over the IV model, the company says. The company designed the excavator so it doesn't have to be trailered for getting to and from the jobsite. It also comes standard with Gradall AutoDrive, a push- button automatic transmission to make road travel easier. Two-step emissions reduction Liebherr's new PR 766 dozer succeeds the previous 416-horsepower PR 764 and is the newest of the company's Generation 6 dozers, which debuted in 2013. Powered by a 422-horsepower, 8-cylinder Liebherr engine, the dozer meets emissions compliance standards in two techno- logical steps, according to the company. First, using company-designed common rail injection and engine control enables Liebherr to minimize particles in the engine. The company also uses selective catalytic reduc- tion-only, which allows it to forgo the use of a diesel particulate filter. The dozer has a hydrostatic drive, allowing the ability to run at a constant rpm and save fuel.
