Well Bilt Industries, Williston, Fla., supplied a 122 2/3- by 34-foot (37- by 10-m) door with a 150-mph wind load for the west common hangar for Falcon Trust Air, a top-ranked fixed base operator, at Tamiami Kendall Airport in Miami.
The Super Bi-fold door was constructed using 8- by 2- by 1/4-inch
(203- by 51- by 6-mm), 8- by 2- by 3/16-inch (5-mm) and 8- by 4- by 3/8-inch (203- by 102- by 10-mm) rectangular steel tubes, in addition to 8- by 3/8-inch HRS plate. The door is powered by eight 2-horsepower units with a gear reduction of 240:1. The door also features an auto-lock system, safety edge and warning bell, as well as a keyed lockout control panel and fused safety disconnect.
Well Bilt Industries custom fabricates all door hardware for its door systems, and for this project, all hardware was super-sized by 200 to 300 percent to accommodate the door’s size, weight, and vertical and horizontal reactions. The Dade County-approved Super Bi-fold door was delivered in May 2008, and the project was completed later that year.
