A major theme park owner was concerned of a fall hazard on a platform that required maintenance services at night, but during the show needed to remain clear of obstructions. The solution was a pop up rail that locked in place when necessary to protect maintenance staff, but could fold down when not in use.

​Further complicating the situation were the tight clearances around the equipment. Hageneering performed a motion study to ensure that the rail would clear all surrounding equipment throughout its entire range of motion.

​In order to comply with the rigorous safety standards associated with guardrails, Hageneering did a comprehensive stress analysis on the system.
