3. Product Description
General Description
NOVA’s NAS Series Premium Air-Powered Dock Levelers
incorporate the use of a low pressure, high volume air system
to raise and lower the platform. A single push-button activates
the air power system to raise the leveler and extend the lip.
Unit conforms to OSHA, U.S. Department of Commerce
Standard CS-202-56 and is manufactured in compliance with
the American National Standard of Safety Performance and
Testing of Dock Leveling Devices (ANSI) MH 30.1.
Operation
The push-button is depressed and held allowing the electric
blower to fill the air bladder which raises the platform. When
the fully yieldable lip extends at the top of the cycle the button
is released allowing the extended lip and platform to lower
onto the trailer bed. Upon trailer departure, the lip can be
retracted and the unit restored to a safe cross-trac position.
In-use and stored positions are achieved without manual
operation. Operable range is 12-inches above/below dock
level. Platform is allowed to automatically float up and down
with trailer movement.
Structural
The platform is constructed of 1/4-inch thick four-way high
tensile 50,000 minimum yield A572 safety tread plate.
Platforms are reinforced and supported by full-length 6-inch
high-formed C channels for 25,000-pound Comparative
Industry Rating (CIR) capacity to 40,000-pound CIR units,
full length 6-inch height structural channel for 45,000-pound
CIR units and full length 6-inches high structural channel and
I-beams for 55,000-pound CIR units, all welded to the deck
for firm structural support.
Front and rear header plates are 1/2-inch thick × 7-inch high
hot-rolled steel. NOVA’s NAS series lips are four-way safety
tread plates, the 25,000-pound CIR is 1/2-inch thick and the
30,000, 35,000, 40,000, 45,000 and 55,000-pound CIR
are 5/8-inch thick. The standard lip length is 16-inches on all
capacities. Hinge tubes have a 1 3/4-inch outside diameter
(OD) × 5/16-inch wall, 1 7/8-inch (OD) × 3/8-inch wall or
2 1/8-inch OD × 1/2-inch wall depending on CIR. All lip
hinge pins are 1-inch diameter M1044 steel. Steel header
gussets are standard on all models with 35,000-pound CIR
and above. All units have grease fittings as standard. All
platforms are designed to compensate for up to 4-inches of
canted trailer bed.
Electrical
Electric blower motor is 115V single-phase, 1400-watts
drawing 11 amps at startup. Electrical control panel is non-
metallic NEMA 4 enclosure. All components, connections and
wiring are UL listed or recognized.
Safety Features
Retractable cross-trac legs of solid steel bar construction provide
multi-position safety at dock level and below. A self-contained lip
extension mechanism yields under impact from incoming trailer. The
leveler is equipped with built-in maintenance strut that is lockout/
tagout compliant night lock security. Full-range telescoping toe
guards close osides even in highest upward position.
