Aerospace Sub-Grade Engine Lift with Automated Locking Pins
Introduction
Raising Engines from Sub-Grade Service Areas for Safe, Ergonomic Maintenance
Project Challenge
The customer required a solution to bring engines up from a below-grade work area to a comfortable and safe height for servicing. In addition to smooth, vertical travel, the lift system needed to work within the constraints of an existing iris floor mechanism. The iris platform opens/shuts around the engine securing it onto of the lift platform so work can be safely conducted on the jet engine.
Our Solution
Autoquip engineered a fully pit-mounted vertical lift system that raises heavy engines from a recessed service area to a technician-friendly height. The circular platform design supports stable and balanced engine placement, while the lift’s travel path aligns precisely with the existing floor opening.
To ensure safety and stability, automated locking pins engage at specific points in the lift’s travel. These pins:
Secure the platform at working height for safe load transfers.
Prevent unintended movement, protecting both the equipment and surrounding infrastructure.
Operate automatically with sensor verification to ensure pins are properly engaged before the lift can be used.
Key Features:
Pit-Mounted Engine Lift: Enables vertical travel from a sub-grade service area to working height.
Circular Platform: Provides stability and easy access around the engine during maintenance.
Iris Floor Integration: Designed to fit seamlessly with existing floor openings.
Automated Locking Pins: Locks the platform in place to ensure safety during service operations.
Sensor-Controlled Engagement: Confirms secure locking before platform motion is enabled.

The Results
Improved Ergonomics: Raises engines to an optimal working height, reducing technician strain.
Safe Load Handling: Locking pins add mechanical security during maintenance procedures.
Infrastructure Compatibility: Works with the customer’s current floor setup without requiring major structural changes.
Reliable Operation: Automation and sensor control minimize operator error and maximize uptime.
Conclusion:
Autoquip’s custom-engineered pit-mounted engine lift is a purpose-built solution that improves both safety and efficiency in heavy engine maintenance. By lifting engines from a sub-grade service area and securing the platform with automated locking pins, this system supports safer, more productive service operations tailored to the facility’s existing layout.
