FAIRFAX, Minn. — Wind pins lock the door to the building structure similar to a bolt in a standard door lock. They are an integral structural link between the door and the building to resist negative wind loads. Schweiss Doors hydraulic doors now includes the application of hydraulic wind pins.
Locking in wind pins – until now – was a manual operation. The wind pin had to be manually raised prior to opening and manually lowered after closing the hangar door.
Schweiss Doors streamlined the process with its newly engineered design of an automatic hydraulic wind pin. The system allows the user to push the up/down control button or remote opener to open of close the door securely and set the wind pin in place.
The hydraulic-operated wind pin rises out of the floor socket and the door automatically opens eliminating the chance of forgetting to raise the wind pin, which could result in damage to the door or floor socket. The wind pin is mounted to the interior frame of the door and extends down into the building floor.
