Gomaco has enhanced its bridge deck and flat slab finishing technology with the introduction of a new, high-production truss-mounted screed for paving bridge decks, flat slabs and floors. It allows contractors to economically finish city streets, concrete floors, bridge decks, tunnels and canals at widths up to 31.7 m.
This new high-production screed can advance up to 1.2 m in a single pass, significantly reducing finishing time and providing savings on concrete delivery costs and total project labour. The screed features a 1.7-m-long leading auger with a high-production strike-off action that reduces the number of puddlers needed out front.
A 1.5-m-long finishing cylinder, directly behind the auger, compacts and finishes the concrete in a single pass. A 1.8 m trailing screed delivers the final finish to the surface of the concrete with an innovative Gomaco-designed vibratory system.
The new screed with a patent-pending design for tilt and skew is mounted to the Gomaco C-450 truss system. The new mount is instrumental for the optional 3D package to finish to a 3D design model.
