Replace aging bifold, counterweight, or bottom-rolling door systems with a modern hydraulic system — without costly structural modifications. We increase both width and clearance in a single installation.
The majority of airports built before 2000 were equipped with bifold, counterweight, or bottom-rolling door systems. These systems are aging out — they're slow, require significant headroom, develop alignment issues, and are increasingly expensive to maintain.
EvoMotion specializes in replacing these systems with modern hydraulic doors — and we do it without requiring the structural modifications that other manufacturers insist on. Our outside-mount installation approach actually increases both the width and the height of the existing opening.
The result: a faster, quieter, more reliable door system installed in 3–5 days with minimal disruption to your operations.

Our outside-mount approach is specifically designed to avoid modifying the primary structural members of the building. In most cases this preserves the building warranty. We recommend confirming with your building manufacturer before proceeding.
