DST® technology drives more efficient dock operations

Integrated into the VANTRAAX® system, Dock Stabilizing Technology™(DST®) represents the latest technological advancement that addresses loading dock issues of trailer drop and walk. DST consists of an optimized plumbing system including our patented HEIGHT CONTROL DIFFERENTIAL DUMP VALVE™(HCDDV™).

Hendrickson installs the HCDDV and adjusts the system to the correct ride height at our factory to help ensure optimum performance in the field. New plumbing also simplifies installation and maintenance.

With activation of parking brake, DST automatically exhausts twice as fast as traditional configurations. This allows the trailer to rest on the air-spring bumpers before the parking brakes fully engage, thus eliminating further trailer drop.
