BOMAG CR 820 Series 8-foot-class asphalt pavers feature a new operator’s platform, new controls, and improved visibility. The paver has a 160-horsepower diesel engine that meets Tier 4-Final emissions standards and a 10-ton hopper. Typical projects for the new machines include parking lots, pavement overlays, development streets, county highways, and interstate shoulders.
Both the tracked asphalt paver and wheeled asphalt paver, the CR 820 T and CR 820 W, respectively, incorporate significant upgrades to the operator’s platform. New dual swing-out seat and consoles provide improved visibility from both the left- and right-hand sides of the paver, and the company’s “Sideview” feature swivels the seat and console outward at four differing angles to enhance views to the sides of the paver and screed end gates. The platform floor’s open-grate design permits direct-line sight to the spreading augers.
A new 7-inch multi-function color screen display at each console provides critical operating functions, gauges, parameters, and fault messages, the latter allowing troubleshooting at the jobsite to improve serviceability and paver uptime. New blade-type toggle switches, each controlling a single paver function, are designed to increase switch reliability and to provide fast, easy replacement anywhere, anytime, says the manufacturer.
A new sound-insulated composite engine hood is designed to reduce paver sound levels, and the hood’s sloped design provides a clear view into the hopper from the operator’s seat. Hopper wings are securely held in the up position with manual locks, improving safety while servicing the machine, says BOMAG.
The CR 820 Series incorporates Three-Point Suspension “to float the paver over subbase irregularities and maintain preset screed slope and grade, delivering higher mat smoothness over commercial pavers with a fixed rear suspension,” says the company. The Frame Raise System allows raising and lowering the rear of the paver to adjust the head of material at the augers. The Smartrac feature automatically maintains proper track tension.
The Stretch 16 hydraulically extendible screed permits variable paving widths from 8-16 feet and a maximum paving depth of 12 inches. Quick-connecting extension kits can extend width to a maximum paving width of 20 feet. An automated screed lock keeps the screed securely in a raised position for transport, maintenance, and storage.
