The 4800’s new skewable power crown adjuster can be mounted in-line on a straight paver or positioned on the frame at the skew when contractors are paving decks with a skew angle.
Today’s Terex Bid-Well 4800 bridge paver boasts new features that improve the machine’s flexibility and ease of operation. The new fogging system offers adjustable and removable spray nozzles that make the system even more user-friendly. Located on each side of the paving rollers, at the burlap drag and drag pan, the independently adjustable nozzles can be positioned to direct the fog where it is required to adjust for wind, mix conditions or to certain specifications. New polyethylene tubing eliminates corrosion within the system to improve system uptime, according to the manufacturer.
The 4800’s new skewable power crown adjuster can be mounted in-line on a straight paver or positioned on the frame at the skew when contractors are paving decks with a skew angle. This optional system simplifies making crown adjustments when paving at extended machine widths. The power crown adjust allows the operator to make quick crown adjustments on-the-fly as the paving carriage reaches the end of the paver.
Two new 23 hp (17 kW) evaporative emissions (EVAP) Tier IV-compliant gas engines power the 4800. One engine powers machine function and movement, while the second engine provides dedicated power to the paving carriage for more consistent paving operation. The new engines meet current emissions standards, improve the operating environment around the machine and provide more fuel efficiency than previous engine models.
The Terex Bid-Well 4800 paver displayed at World of Concrete in Las Vegas was equipped with several options that tailor-suit the paver to meet job site conditions. The available 15-in (38.1-cm) Rota-Vibe system on the show machine’s paving carriage is 30 percent larger than the standard system. This provides longer machine advancements, advantageous when paving streets and highways.
The paver’s two double-flighted augers efficiently meter the concrete in front of the paving carriage. Dual, 5-ft. (1.5-m) long paving rollers provide an improved finish to the concrete surface. The paving carriage on display was equipped with the available dual drag pan arrangement, which helps contractors achieve a better concrete seal and enables the pans to drag directly to the side of the slab, according to the manufacturer.
The show unit featured two leg options available to paving contractors. By offering zero-clearance paving, the machine’s optional swing leg design gives paving contractors an edge when paving in tight site conditions, such as overlays next to live traffic lanes and new bridge construction adjacent to the existing bridge. An available pivot leg design for the 4800 improves paving efficiency when working on severe cross slopes of 6 to 8 percent. This option allows the leg to be pivoted to a true perpendicular position, removing stresses on the side rails and eliminating the need for extra shoring.
With its 48-in. (122 cm) truss frame depth, the 4800 offers standard paving widths ranging from 36 ft. to in excess of 170 ft. (51.8 m). The 4800 paver display unit was set to a 36-ft. (11.0-m) paving width and was equipped with poly drive bogies for additional traction when paving steep grades.
