  • Ability to adjust automatically to trailer motion ensures compatibility with air-ride suspension systems.
Green Power
  • Powered by electricity, the HVR303 is an environmentally sustainable alternative to hydraulic systems.
  •  Low operating cost: only pennies an hour.
  •  Can be interlocked with Blue Giant air-powered dock levelers to build a ‘green’ loading dock solution, allowing builders and developers to qualify for government incentives as well as project the image of an environmentally responsible business.
Intelligent Touch Controls
  • The Blue Genius™ Gold Series II Touch Control Panel features include an LCD menu screen, function buttons and a flat-surface keypad with unique touch sensors.
  • Interior and exterior LED lights keep drivers and warehouse personnel advised of safety conditions.
