Lift models vary per size (lift
model numbers indicate lift
dimensions). NVL Series lift
models can be equipped with
left or right side pump modules
as needed. A left side pump­equipped lift model is depicted
in the Lift Terminology Illustra­tion (NVL917IB). Right side
pump lift models are a mirrored
image of rear pump models
(pump module located on op-

posite end of base plate).

Lift operation procedures are
identical for all NVL Series
lift models. The operating
instructions contained in this
manual and appearing on lift­posted operating instructions
decals address the lift control
switches and the correspond­ing lift functions. Instruc­tions are provided for manual
operation of the lift in event of
power or equipment failure.

Lift Components

Refer to the Lift Terminology Il­lustration on page 4.

Pump Module: The lift-mounted
pump module consists of the
hydraulic pump, the manual
hand pump, the electronic control
board and electrical components
that power the lift electric/hydrau­lic systems.

Hand-held Pendant Control:

The hand-held attendant's
pendant control is connected to
the pump module. The hand­held pendant is equipped with
two rocker switches, (UNFOLD,
FOLD, DOWN, and UP). The
momentary switches activate the
automatic lift functions.

Lift Frame: The lift frame con­sists of the base plate, threshold
warning plate, towers, parallel
arms, vertical arms, platform
pivot arms and handrails. Two
main hydraulic cylinders are
housed in the parallel arms.
The electrical/hydraulic powered
lift frame components mechani­cally unfold, lower, raise and fold
the lift platform assembly.

Platform Assembly: The lift
“stacking” platform assembly is
made up of an inboard platform
section and an outboard plat­form sections (each section con­sisting of a steel tubing frame
with grating surface). The inner
roll stop/bridge plate assembly
(IB) is mounted on the inboard
platform section. The outboard

platform section is equipped with
the outer barrier.

™

Lift-Tite

Latches: The spring-

loaded latches prevent the
platform from unfolding from the
stowed position in the event of
platform drift. Further details

™

regarding Lift-Tite

latches are

provided on pages 16 and 17.

Outer Barrier: The spring-loaded
automatic outer barrier (outboard
roll stop) provides a ramp for
wheelchair loading and unloading
at ground level. Photos and

Page 6

Lift Terminology

further details regarding the
outer barrier are provided in
the Operation Notes and De­tails section (pages 19-21).

Inner Roll Stop: NVL Series
lift models are equipped with
an automatic inboard roll stop
that also serves as the bridge
plate. The roll stop bridges the
gap between the lift platform
DQGWKHYHKLFOHÁRRU7KHLQ­ner roll stop/bridge plate auto­matically rotates from the hori­zontal position to the vertical
position as the lift lowers and
raises. Further details regard­ing the automatic mechanical
inboard roll stop are provided
on pages 18 and 19.

Vehicle and Lift Interlocks

Braun Corporation NVL Series
lifts comply fully with all NHTSA
vehicle and lift interlock speci-

ÀFDWLRQV9HKLFOHPRYHPHQWLV

prohibited unless the lift is fully
stowed and the lift will not func­tion unless the vehicle is parked
and secured.

The NVL features a visible
and audible threshold warning
system that will activate if the
threshold area is occupied when
the platform is one inch or more

EHORZÁRRUOHYHO

The inner roll stop and outer
barrier sense weight to prohibit
lift operation. The lift will not

function if the inner roll stop or
outer barrier are occupied. The
lift platform cannot be folded
(stowed) if occupied.

The inner roll stop features a
locking mechanism that prohibits
the platform from lowering if the
lock does not engage. The lift
platform cannot be raised more
than 3" above ground level un­less the outer barrier is in the
vertical position.
