Flugzeug-Windkanal-Test-Wartungsplattform | Schwerlast-Scherenhebebühne für Triebwerkstests
Überblick über das Projekt
This heavy-duty fixed scissor lift is engineered for aircraft engine maintenance in wind tunnel test cells. Installed at the tunnel entrance, it provides technicians a stable, precision-positioning platform during full-thrust engine operation.
The system utilizes proportional valves for synchronous control of multiple lifting units, integrates string potentiometers for real-time stroke feedback, and incorporates stainless steel bi-directional swing gates with position monitoring to ensure operational safety and compliance.
