This machine is fabricated to transport the pre-cast box beam from the casting yard to the rear of the launching gantry and feed beams to the launching gantry. The structure is monolithic, herringbone type, with wing beams connected with main beam that guarantees the maximum stability and safety along the different routing and during the steering operations. Three points isostatic balance system greatly ensures even force on the tyre trolley to avoid overload on deck and to keep the concrete box beam standing on one flute surface.
1.1 Working conditions ·Be suitable for box beam 32m, 24m and 20m’s transportation. ·Surmountable slope 5 % ·Surmountable transversal slope 4 % ·Min. radius of the bridge 1200m. ·Wind speed: 72km/h with load, 144km/h without load 1.2 Main technical characteristics ·16 axles for 900T capacity ·Double effecting shock absorber mounted on wheel bogie ensures that the main beam is under force, and make sure that the trolley is balanced when accidents happen. ·Self-aviation system can be equipped . ·Hydraulic brake for balancing control when start and brake. ·Chain transmission for the small rolling device on top of the trolley creates a safe and stable operation.
