A GOMACO GHP-2800 paver with the new 5400 series mold and bar inserter attachments slipforms a project in Iowa.
Las Vegas, Nevada -- GOMACO Corporation is proud to introduce the new 5400 series paving mold, designed with a structural integrity that is unmatched in the industry. The new series also includes a rear-loading, front-inserting 5400 series bar inserter, along with other bar placement attachments. The new 5400 series mold and bar inserter were introduced at World of Concrete 2010, displayed on a GOMACO two-track GHP-2800 paver.
The mold, with a 54 inch (1372 mm) finishing length, has a new “box” design and durable 0.5 inch (13 mm) paving skin for structural integrity. It features a spreader plow, independent of the mold, or an optional auger to spread the concrete across the paving width. A newly designed strike-off is mounted to the paver’s mainframe, independent of the mold. The strike-off has a modular design with a wedge-lock system for easy width changes. It has hydraulic crown adjustment and up to 10 inches (254 mm) of hydraulic height adjustment. The new mold also features hydraulic Vertical Hinged Sideplates (VHS), self-contained to the inside of the mold, allowing minimum track clearance.
The mold was built to be easy to assemble, with inserts that are bolted together with front and rear alignment pins. The mold is mounted to the paver with pivoting beams. The pivoting ability eliminates any stress points. Vertically adjusting mounts on the mold allow precise leveling of the mold to the paver. A front and rear T-bar at the top of the mold adds structural integrity and is utilized for attaching paving accessories. A new vibrator mounting tube attaches to the T-bar on the mold and can now be vertically raised or lowered to accommodate paving conditions or transporting needs.
The mold was also built to be versatile. The 5400 series mold will have telescoping end sections with 12 inches (305 mm) of width variation on each side of the paver. The transition adjustor is self-supported and driven with a 3.5 inch (89 mm) ACME screw for up to a six inch (152 mm) crown. Split, pressure-compensated sideplates allow a standard paving depth from zero to 24 inches (0 to 610 mm). The mold will also be available with edge slump, batter adjustment and optional tamper bar.
The new 5400 series bar inserter offers ease of use with rear loading from the paver’s work bridge, while the bar is inserted in front of the mold. It features a reliable and highly efficient bar loading chain system with bars traveling in a flat, straight path. The bar insertion process and timing is controlled by GOMACO’s new G+ system. The new inserter mounts to the 5400 series mold’s T-bar, where it can allow on-the-go crown changes while maintaining a constant bar depth. Individual depth guides on the right and left side of the bar inserter keep the bars parallel to the top of the slab during insertion. The system is able to accommodate #3 to #8 diameter bars between 20 to 40 inches (508 to 1016 mm) in length, and inserts the bars up to 7.5 inches (191 mm) deep into the concrete slab. The bar bundles are loaded into a bar box that is mounted to the paver’s rear T-rail for easy access and loading of the bar magazine. The bar loading chain system and bar magazine are capable of holding up to 50 bars.
