Structural design of Schweiss Doors hydraulic doors now includes the application of hydraulic wind pins.
Wind pins lock the door to the building structure similar to the bolt in a standard door lock and are an integral structural link between the door and the building to resist negative wind loads. Until now, locking in wind pins was a manual operation, according to Schweiss, requiring a walk back to the center of the door to manually lift the win pin out of the floor socket, and a walk back to the door control station to proceed to raise the hydraulic door. When the door closed, the operator had to again manually reset the win pin into. The company’s 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.
