Bridging System
Bridge Functions
The widen board is in folded condition during transportation. Each guide beam is inserted into the corresponding bridge section for the convenience of integrated transportation and lifting. During operation, the lifting of the bridge between the transportation vehicle and erection vehicle is accomplished by the crane on the erection vehicle. The oil for the hydraulic system is supplied by the erection vehicle to accomplish bolt connection between bridges.
Bridge Composition
The bridge equipment is the direct load-bearing component to ensure the designed vehicles passing through the obstacles. One set of bridge equipment is composed of 4 middle bridge spans, 2 end bridge spans, 4 middle guide beams, 2 end guide beams, widen board, ramp, and hydraulic system.
Bridge Span
The bridge span is divided into middle and end bridge span. The end bridge span also is divided into end bridge span with bolts and end bridge span without bolts, which are all three-chord trusses. The six longitudinal chords are the main bearing components of the two groups of three-stringed steel truss. The upper double and three ear connectors are welded at the ends of the upper chord. Single and double ear connectors for group bolts are welded at the end of the bottom chord. Two three-chord trusses are connected by a transversal chord and form the main structure of the bridge body. The joints between bridge spans are connected by hydraulic bolts. A Roller system is set up inside the bottom chord of the bridge span to accomplish the erection of a built-in guide beam and fixation during transportation
Hydraulic System
The bridge hydraulic system includes a double-joint control valve, bridge
span hydraulic system, guide beam hydraulic system, and support leg hydraulic system, The bridge span bolt and guide beam bolt are powered by the erection vehicle through fast connectors and controlled by a manual valve. The bolts of the bridge span and guide beam cooperate with the erection vehicle to accomplish the connection and fixation between the bridge span and the guide beam. The guide beam support leg is powered by the manual pump to accomplish the support and retrieval operation
