Aircraft Hangar Doors

As of January 31, 2022, U-S Safety Trolley will no longer be accepting new system orders for our Span-Guard, Tri-Bar/Four-Bar, PowerGlide, or Tightwire products. Please reach out to your local representative for more information and inquiries about replacement parts (subject to availability).

The doors that house some of the largest aircrafts in the world need to have a reliable, heavy duty method of opening and shutting every day. In the past, hangar doors were predominantly run by festoon systems that would commonly break and require regular maintenance from everyday wear and tear. Today, two of the U-S Safety Trolley products provide joint-free mobile electrification systems that have been proven to effectively operate the hangar doors of the world’s largest airlines.

The Tri-Bar/Four-Bar system contains solid copper conductors that come in 100 and 125 amps. The system is jointless, meaning drastically less maintenance is required compared to a jointed system, and can extend for hundreds of feet, making it the perfect solution for large hangar doors.

Somewhat similar to Tri-Bar/Four-Bar, PowerGlide is a conductor bar system with retractable wheels for simple insertion and maintenance. This system is rated at 90 amps and is compact and lightweight by design. In addition to being easy to install, PowerGlide’s aluminum housing and optional closure strip ensure dirt and grime stay out of the power path.
