The type DES sealing apron features a stable structure and tear-resistance, characterized by great cross stiffness, adaptable to different truck types. This facilitates multi-purpose usage.

Framework:

The front and rear frames are not rigidly connected but instead are flexibly connected by a special cushioning system. These connections reduce the chances of damage from trucks hitting the dock. Effective sealing is also ensured when docking is less than perfect. The tilt‑arm structure is equipped with protective chains. Unlike scissor arms where the apron seal is stretched with each use, this structure retains its attractive appearance longer.
