Spec-Dor’s Automatic Guided Door (AGD) system features independently powered, wirelessly controlled door panels. Each panel moves on its own, guided by a central control system. The real-world benefits include increased operating speed, reduced labor and maintenance, and improved safety and reliability. In an AGD installation in Baghdad, Iraq, door opening/closing time was reduced from 15 minutes to 3 minutes, and walk-beside operation was eliminated.
The US Army Corps of Engineers commissioned Spec-Dor to create a high-flexibility door system for a state-of-the-art maintenance hanger at Wheeler Army Airfield in Oahu, Hawaii. The doors had to facilitate high-frequency operations for up to six helicopters simultaneously. Configuring six independently motorized panels on parallel tracks allows single bays to be opened without opening the entire hanger. For the tropical storm-prone ocean climate, the doors also meet the with US Dept. of Defense Unified Facility Criteria (UFC) and the Hawaii Building Code (HBC) wind-load codes for great than 145 mph, and uses corrosion-resistant steel and sealed bearings to withstand salt-laden air.
Major door replacement can take a hangar out of commission for weeks. A regional airline at Richardson International Airport (YWG) in Winnipeg, Canada, couldn’t afford the downtime. The Spec-Dor solution: build the new door in front of the old one. Adding a new external steel framework to support the new hangar door system allowed the hangar to remain in operation with minimal disruption. The decades old structure gained significant energy efficiency, faster, smoother operation, and compliance with current safety standards.
Spec-Dor’s engineering-first approach thrives on unconventional hangar door situations. At the Utah Test and Training Range (UTTR), a major facility of the US Department of Defense, the focus is on missiles and aerial combat systems. A tall, mobile hangar required a highly secure vertical door system. Spec-Dor designed a retrofit 43-foot-tall custom door, precision engineered to accommodate the flex of a moving structure, Several unique Spec-Dor technologies were employed, including a time-tested passive fail-safe system, a unique drive system with counterbalanced weights, and a structural design that allows for standard shipping of non-standard sized hangar doors. A personnel door was included for emergency egress.
