First, the shuttle bus needs to be accurately aligned with the formwork platform loaded with heavy bridge deck components on the conveyor line. When the formwork platform loaded with bridge deck components (hereinafter referred to as the formwork platform component) is driven by the supporting rollers to move to the shuttle bus, the formwork platform component is in place and the shuttle bus is started to transport the mold components to different workstations to complete the transportation. This requires the shuttle bus to have the following characteristics: 1) It can carry the narrow and long formwork platform components with large tonnage; 2) The process from the conveyor line to the shuttle bus must be a smooth transition; 3) The shuttle bus is required to have high synchronization accuracy during transportation, etc.
