Terex Bid-Well 4800 Paver for Bridge Decks, Roads and Other Flatwork
The Terex Bid-Well 4800 paves both complex bridge designs and standard-duty flatwork with equal ease and efficiency, improving machine utilization and increasing return on investment. The 4800 automatic roller paver makes quick work of slab-on-grade paving projects. These include everything from urban development roads to port decks and parking lots.
The automatic roller paver’s adaptable frame design is the key to quickly paving complex slabs that flair or require variable or inverted crowns. To adjust from a perfectly flat slab, machine crown points can be manually set at any hinge on the frame, enabling the contractor to establish single or multiple crowns in the slab from +6% to -1.9%. The frame rides the rail on four heavy-duty, 6-inch (15.2cm) diameter legs and eight bogie screed rollers, offering an 11.5-foot (3.5m) total span. “Our wide wheelbase helps to reduce machine pivoting from any slight deviations in the rail to help boost surface flatness,” said Service Manager for Terex Bid-Well, Dean Johnson.
The Terex Bid-Well 4800’s 48-inch (121.9cm) deep truss frame offers standard machine lengths from 36 to 120 feet (11.0 to 36.6 m) for paving variable widths from 12 to 116 feet (3.7 to 35.4 m). Standard 18-foot (5.5m) truss end segments offer up to 15 feet (4.8 m) of leg travel to each side of the machine for on-the-fly variable width paving, so contractors can vary paving width up to 30 feet (9.1 m) without rebuilding the truss frame.
“Contractors using the 4800 have said they can pave twice as much concrete in half the time with half the labour force than paving one, 12-foot (3.7m) wide slab at a time with a vibratory screed.” - Larry Eben, Terex Bid-Well District Manager
Powered by its own standard 23-hp (17kW) Tier 4 compliant gas engine, the 4800’s paving carriage rides along the truss via a heavy-duty dual chain drive. Innovative dual spud vibrators impart vibration right up to the edge of the slab and consolidate up to 30 inches (76.2 cm) of concrete. The carriage’s automatic pivot feature ensures that excess concrete is continually pushed forward by the two, 8-inch (20cm) diameter rotating strike-off augers.
The 4800’s Rota-Vibe system sets this automatic roller paver apart from the competition. Rota-Vibe reconsolidates the top 2.75 inches (6.9 cm) of concrete, delivering a denser and more uniformly consolidated surface. Dual 5-foot (150cm) long finished rollers improve surface smoothness and feature independent rotational direction control to adapt to concrete conditions and enhance finish. The machine’s height-adjustable drag pan allows operators to adjust the pressure applied to the concrete surface to provide a better seal.
