marketplace | by Amy Materson AMaterson@randallreilly.com PRECISE PAVING Volvo Construction Equipment's new tracked pavers provide power and precision for delivering a perfectly smooth mat in demanding conditions. The P8820C ABG can pave widths up to 42.7 feet and place up to 992 tons per hour, and the P7820C ABG can pave widths up to 36 feet and place up to 992 tons per hour. The pavers are equipped with D8 Tier 4 Interim six-cylinder, 7-liter engines that deliver 268 and 235 horsepower, respectively. Designed to maximize fuel economy, the machines conserve fuel without affecting paving operation via an operator-selected smart power mode. The smart power mode lowers the power to 1,600 rpm when engaged, which reduces fuel consumption by up to 30 percent. When combined with sound-lowering components, the noise level can be reduced by up to 50 percent. An ergonomically designed cab provides operators with a direct view into the hopper, auger channel and work area for all around visibility, and the seat position and control pane can be adjusted. Both pavers feature EDI T PICOR'S K a large hopper – 30,860 pounds on the P8820C and 29,760 pounds on the P7820C. An optional front hopper apron that empties material at the front of the hopper into the conveyor system virtually eliminates over-spill. The units have independent reversible hydrostatic drives for both bar conveyors and augers that ensure paving material is evenly distributed to both sides of the screed. Both fixed and variable extending screeds are available that can be used on bituminous, concrete base, aggregate and more. MANEUVERABLE ROLLER Efficiently compact granular and cohesive soils with BOMAG's BW211-50 Series of single-drum vibratory rollers, which includes the BW211D-50 smooth drum roller and the BW211PD-50 padfoot roller. Powered by a Tier 4 Interim 120-horsepower Deutz diesel engine, the rollers feature ECOMODE, a fuel conservation system. The rollers deliver frequencies of 1,800 and 1,980 vibrations per minute across an 84-inch operating width. The BW211D-50 generates 53,100 and 32,141 pounds of centrifugal force in high and low amplitude, respectively, and the BW211PD-50 delivers 61,825 and 37,434 pounds of centrifugal force. The series features a 12-degree oscillating angle and 35-degree steering angle for maneuverability on the jobsite, and a single lever control manages travel and vibration modes. The rollers offer 47 percent max gradeability with and without vibration. Heavy duty 12-ply tires and a rear axle with no-spin differential deliver traction in difficult conditions. The BW211-50 Series features a vertically opening polymer hood for quick access to the engine, hydraulics and service points. Options for the series include compaction measurement and control systems; front and rear working lights; padfoot or smooth drum segment kits; front frame or diamond tread rear tire ballasts; ROPS cab with heating, air conditioning, swivel comfort seat, CD radio with auxiliary input and rotary beacon; and speedometer, voltmeter, frequency and tachometer gauges.
