Blaw-Knox’s PF-7110B Asphalt Paver
For highway class paving power, the 10-foot PF-7110B tracked asphalt paver from Blaw-Knox Corporation, Orlando, Florida, features a Tier 4 Final D8 235-horsepower (175 kW) engine designed to improve fuel efficiency by up to 5%. Here’s how it works:
First, the paver operator takes his or her position in the rotating and extending operator seat for 360-degree paving visibility, including unobstructed views into the auger tunnel and hopper.
He starts the Tier 4 Final D8 engine, which offers 235 horsepower at 1,800 rpms.
When the operator signals the haul truck driver to do so, he will charge the 13-ton-capacity hopper and the operator will push forward, paving at a maximum speed of 224 feet per minute.*
Material moves along the conveyor system, to the auger tunnel, where independent augers feed it under the screed. For the PF-7110B tractor, several Blaw-Knox screeds are available, ranging in extendable widths up to 20 feet (with the Ultimat screed) and allowing mat depths of up to 12 inches, according to the manufacturer.
*Best practices suggest paving speeds not exceed 25 fpm for typical projects. Monitor your speed to match the plant’s production or reliable haul truck delivery to minimize starts and stops during mainline paving.
