Inboard-Mounted Safety Latch Mechanism for Preventing a Walkway Platform Flip Door From Being Raised Without a Guardrail Installed
In an example, a system is described. The system includes a guardrail having a post, and the post having a post dog. The system also includes a latch eye configured to be coupled to a flip door. The system also comprises a safety latch mechanism configured to be coupled to a fixed structure and including a body, a socket configured to receive the post, and a door latch rotatably coupled to the body and biased in a latched position that is configured to engage with the latch eye and thereby retain the flip door in a lowered position. Based on the post being inserted into the socket of the safety latch mechanism, the post dog engages with and rotates the door latch from the latched position to an unlatched position, thereby allowing the flip door to be raised from the lowered position to a raised position.
