TEMPORARY BRIDGE FOR PASSAGEWAY OF CONVEYOR

摘要

The present invention is to provide a self-closing cross-linking device that is installed so that workers can walk on the passage of the truck for transporting the work in the shipyard. On one side of the trolley, the one end is pivotally supported on the wall of the passage while the other end is freely positioned on the floor of the workshop to allow sliding. At the position adjacent to the shaft, a locking device for restraining or releasing the shaft is installed. As a result, when the bridge frame is pushed by the trolley at 90 ° or -90 °, the locking device is caught by the locking device so that it does not impede the passage of the trolley. It is to return to the crosslinked state.
