The WSH series vibratory truss screed, which spans up to 65 feet, resists rough handling and allows operators to strike off slabs up to 11 inches deep. The 8-hp and 13-hp gasoline-driven models produce 8000 vpm. The pneumatic models produce up to 9500 vpm for low-slump concrete or deep lifts. Vibrators are spaced at 30-inch intervals for uniform consolidation. Multiquip Inc., 800-421-1244,
