BEFORE CHOOSING YOUR DOCK LEVELER,
COMPARE TOTAL UNDER DECK BEAM SUPPORT
As shown, BLUE GIANT provided up to 500% more structural under-deck support than some competitive formed beam configurations. Note, total top deck plate beam support equals number of beams multiplied by the beam width e.g. surface dimension in contact with deck.

BLUE GIANT 'FHC' VS. KELLEY 'FX'
Manufacturers of hybrid dock levelers including air bag design claim that they are better than mechanical dock levelers and less expensive than hydraulic models. In reality, they are power assisted mechanical dock levelers that do not offer all the features that a customer can gain with conventional industry proven hydraulic dock levelers.
BLUE GIANT FHC
KELLEY FX
Hydraulic lip = reliability and no maintenance Mechanical lip = regular maintenance and cost
Rear hinge has 7 support points full width Rear hinge has only 4 support points, partial width
Quiet and fast (up to 1.5 times faster) cycle times Full inflation before operating = more time
Capacities up to 30,000 lbs and up to 80,000 lbs with 'FHC' Capacities up to 50,000 lbs only
Formed box beam deck support with approximately 20 times greater under deck area support coverage Formed tube beam deck support with "flex" design
Easy access and clear visual inspection under deck Maintenance hindered due to air bag location
Available in all common voltages 115 voltage only; requires 10 amp dedicated line
Push-button activated lip control - no extra time wasted, no operator bending over for below floor level trailers Manual chain release activation by attendant required for each below level cycle
Hydraulic fall safe protection maximum of 3" drop Mechanical fall safe protection up to 12" drop
'FX' Comparison
The most significant structural design aspects for all dock levelers are the amount or type of deck support (total width of supporting beams Vs. total width of deck) and how the dock moves to accommodate tilted truck beds. In addition to design parameters, the two primary operating functions of any dock leveler are to raise the deck and extend the lip. Functionally the air bag lifts only the deck, NOT the lip. The 'FX' lip is extended by a mechanical linkage system as mechanically operated dock levelers. The BLUE GIANT fully hydraulic system lifts the deck and extends the lip with separate hydraulic cylinders. Therefore the customer is only receiving 50% powered automatic operation compared to BLUE GIANT fully automatic operation.
