What is the purpose of positive stops on overhead pivot gates?

• A. To limit travel to the fully opened and closed positions.
• B. To allow continuous travel.
• C. To adjust the speed.
• D. To secure the gate during wind.

Answer: (A)

Positive stops define the end-of-travel points for the gate. They are positioned so the gate’s moving parts contact them at the fully open and fully closed positions, causing the mechanism to stop exactly there. This ensures the gate lands in precise, repeatable end positions, which is essential for reliable latching, proper sealing, and safe clearance. It also prevents over-travel that could stress the pivot, linkage, or drive system, reducing wear and potential damage. They aren’t used to keep the gate moving continuously, nor to adjust speed, nor to secure the gate against wind—the drive system controls speed, and wind protection relies on other hardware.
