Universal bridge deck vibrating system

摘要: A vibration system that fits on top of a conventional truss with minimal alteration. The comprises propulsion assembly powering assembly. two parallel rails forming lateral path between ends and supporting mobile carriage. Each rail abutting segments coextensively surmounting the truss. segment attaches at respective cross-beams to define continuous runway for carriage movement. also defines channel chain rack anchored opposite ends. an undercarriage offset platform. rail-spanning frame tracking wheels. motor propels by turning axle terminal pinions entrained about rack. counterbalances reduce torsion. coupling hitch protrudes from platform support elevator vertically displaces gang vibrators deployed retracted positions. hydraulic cylinder coaxially centered sleeves sliding arms couple elevator. plurality quick-coupling pendulous across front. drives multiple via split connected several gearboxes in series. When deployed, vibrator tip thrusts into concrete undulates rapidly selected time. Afterwards, retract moves adjacent vibrated sector until completely traversing They may operate automatically or manually.
