STC Starting Torque Controller
1-11
Figure 1.13 Aircraft Hangar Door
Problem: A chain driven aircraft hangar door was started across-
the-line. The starting torque caused chain alignment
problems. This required frequent inspection and
maintenance.
Solution: An STC controller was installed to provide controlled
acceleration. This minimized the mechanical shock
encountered during across-the-line starting and reduced
maintenance inspection. The digital adjustments of the
STC controller were easily set and did not drift with ag
or vibration.
