ADF Air-Powered

AIRDOCK® model ADF Air-Powered FLEX-LIP® Dock Leveler lip is designed to provide substantial cost savings on equipment maintenance, fragile goods damage and personnel injuries.
Continuous Hinge Safety Barrier-Lip Model ADFB available to prevent accidental fall off of dock. The leveler lip provides level loading for all heights of trailers, even when below dock.


The smoothest transition from the truck bed to the loading dock


AIRDOCK® model ADF Air-Powered FLEX-LIP® dock leveler features NEXT GENERATION AIR™ technology with the patented PROTECTED SINGLE CHAMBER™ balanced bag design and PULL-ACTION™ lift system that does not push on the underside of the deck or pit floor.

Patented Proven Technology

The patented FLEX-LIP® lip design extends automatically as the leveler deck descends and maintains the lip horizontally in all positions of the platform, even in below dock loading operations.
The risk of grounding low clearance pallet trucks and forklifts while loading and unloading is significantly reduced and excessive forklift tire wear, especially in below dock loading operations, is minimized. Personnel injury, caused by whole body vibration, is also significantly reduced, saving on injury claims and employee absence.

When the lip angle is too great, it can result in low clearance vehicles, such as electric pallet trucks impacting the lip or the trailer bed damaging equipment and impeding loading operations.

Low clearance pallet trucks can impact the crown angle, especially in below dock loading operations, resulting in damage to fragile goods and increased wear and tear on the lift truck substantially reducing maintenance, product loss costs and leveler structural fatigue.

Personnel injury caused by whole body vibration is significantly reduced saving on injury claims and employee absence.

Simple. Safe. Easy. Push button power

When the button is pressed the platform rises to its highest position, releasing the button allows the deck to descend the lip to extend into place automatically until the lip rests on the truck floor.
The lip remains in its optimal horizontal position whether the truck is above or below the building floor height.
When loading/unloading is completed, pushing the button again returns the platform and lip automatically to the stored position.

Short Form Specs


The FLEX-LIP® Series Air-Powered dock leveler is designed to provide substantial lifetime cost of ownership savings by reducing equipment maintenance, damage to goods and injury to personnel resulting in increased safety and productivity.
The patented lip activation maintains the lip horizontally on the trailer bed in all positions providing the smoothest transition available from truck bed to dock floor.
The patented lifting system utilizes a revolutionary PROTECTED SINGLE-CHAMBER™ balanced air bag and PULL-ACTION™ design that reduces parts and friction while allowing easy inspection and access to the deck assembly.
The self-contained design provides easy handling & installation with a fully protected bag and a lift system that does not contact the floor of the pit.
The patented self-cleaning lip lug and header plate design provides the strongest front hinge and deck support and does not allow debris to collect in this critical area.
Available in capacity ratings from 30,000 to 50,000 pounds in increments of 5,000 pounds, and standard nominal platform sizes of 6, 6.5 & 7 feet wide x 6,8 & 10 feet long.
Standard features include full operating range telescoping side guards, night security locks, integral lip and deck maintenance supports, safety black & yellow side skirt labels, and two heavy-duty dock bumpers.


The operator presses the control button until the deck is fully raised. Releasing the button activates the AUTO-DESCENT LIP™ system that extends the lip as the deck lowers placing it smoothly onto the truck bed.
The leveler will float up and down and side to side with the truck during loading and maintain a horizontal lip on the bed of the truck at all times.
To store the dock leveler, the operator presses the control button activating the lift system allowing the lip to automatically retract to a pendant position, releasing the button deactivates the air power to store the leveler in a fully supported position level with the building floor.
The standard 16" lip will extend out 11" beyond a 4" bumper and engage a truck 12" above and below building floor level.
Note: Longer lip option reduces above dock service range.


Unitized platform structure with dual side 33% beam to deck weld pattern and continuous welds at the beam to header plate and lugs for maximum strength.
The deck plate, lip plate and beams are constructed from high-tensile steel and safety tread top running surface.
The deck support structure includes dual flange style beams, center deck support and welded side guards for superior strength.
The frame has four upright, two forward supports and a fixed continuous smooth transition rear hinge to eliminate pinch, trip or impact point.
A security lock system prevents illegal building entry when the overhead door is closed.
Full width zinc plated front & rear hinge rods are constructed from SAE 1045 superior shaft and factory coated with anti-seize lubricant.
A single NEMA 4 push-button control operates the 120-Volt fan motor.
