Lift Terminology
Braun NUVL Series lifts are ADA
compliant and comply fully with
National Highway Traffic Safety
Administration (NHTSA) specifi-
cations. The NUVL855RM24 is
commercial oriented (intended
for operation by an attendant).
Public Use NUVL lift models pro-
vide fully automatic operation of
deploy (extend), up, down and
stow (retract) lift functions. The
NUVL855RM24 can be inter-
faced for fully automatic opera-
tion of the power door system.

Introduction:

Page 6
Lift Terminology
regarding the control switches
and their functions are provided in
the Lift Operation section.
Lift Housing: The lift housing
is the metal structure (casing)
mounted under the vehicle which
contains and protects the platform
carriage assembly. The hous-
ing contains all lift components
except the power (pump) module
when the lift is in the stowed posi-
tion.
Platform Carriage Assembly:
The platform carriage assembly
includes the platform assembly,
the lifting arms, the rolling hori-
zontal arms that carry the plat-
form assembly in and out of the
housing and the electrical/hydrau-
lic drive components that power
the lift.
Platform Assembly: The lift
platform assembly consists of the
flat aluminum plate upon which
the wheelchair is positioned, the
outer barriers, the inner roll stop
and shield handrails.
Outer Barrier: The two-stage
outer barrier system consists of a
spring-loaded tall barrier and an
electric actuator-driven short bar-
rier. The two-stage outer barrier
provides a ramp for wheelchair
loading and unloading at ground
level. Photos and further details
are provided in the Operation
Notes and Details section (pages
18-21).
Inner Roll Stop: The NUV-
L855RM24 is equipped with an
automatic inner roll stop that also
serves as the bridge plate. The
Lift Components
Refer to the Lift Terminology Il-
lustration on page 4.
Pump Module: The remote
mounted pump module consists
of the main hydraulic pump, the
manual hand pump, the electronic
control board and other electrical
components that power the lift
electric/hydraulic systems.
Hand-held Pendant Con-
trol: The hand-held pendant is
equipped with four push button
switches, (DOOR, STOW, DOWN
and UP). The momentary switch-
es activate the automatic lift
functions. Simply press the switch
labeled for the intended function.
The lift function labels illuminate
to identify the function(s). Details

Page 7
Lift Terminology
The inner roll stop and outer bar-
riers sense weight to prohibit lift
operation. The lift will not function
if the inner roll stop or outer barri-
ers are occupied. The lift platform
cannot be stowed if occupied.
The lift platform cannot be raised
or lowered unless the roll stop
and outer barriers are deployed
(up).
Vehicle and Lift Interlocks
Braun Corporation NUVL Series
lifts comply fully with all NHTSA
vehicle and lift interlock speci-
fications. Vehicle movement is
prohibited unless the lift is fully
stowed and the lift will not func-
tion unless the vehicle is parked
and secured.
The NUVL855RM24 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 below floor level.
inner roll stop bridges the gap
between the lift platform and the
vehicle floor. The inner roll stop
automatically rotates from the
horizontal position to the verti-
cal position as the lift lowers and
raises. Further details regarding
the automatic mechanical inner
roll stop are provided on pages
17 and 18.
Platform Cable-activated Man-
ual Release System: A cable-
activated manual release system
releases the platform carriage
assembly drive chain to allow the
platform carriage assembly to be
manually moved out (extended)
or moved in (retracted), should it
be necessary. Further details are
provided on page 36.

Page 8
Lift Terminology
Lift Actions and Functions:
Deploy (Extend): Lift deploy-
ment is the action of the lift plat-
form carriage assembly extend-
ing (moving outward) from the
housing and lowering to ground
level when the DOWN switch is
activated or raising to floor level
when the UP switch is activated.
Stow (Retract): Stow is the
action of the lift platform and car-
riage assembly retracting (moving
inward) into the lift housing. Dur-
ing the stow function, the platform
will automatically raise or lower to
stow level before retracting into
the housing.
DOWN - Platform Lower: Down
is the action of the platform lower-
ing from stow or floor level posi-
tion to fully-lowered (ground level)
position when the DOWN switch
is pressed.
DOWN - Outer Barrier Un-
fold (Down) - When the plat-
form reaches the fully-lowered
(ground) position and the DOWN
switch is continued to be pressed,
the outer barriers rotate down-
ward from vertical position to
ramp position.
UP - Outer Barrier Fold (Raise):
From ground level, the UP func-
tion automatically raises (rotates)
the actuator activated outer bar-
riers to the upright (vertical) posi-
tion before the platform raises.
UP - Platform Raise: Up is the
action of the platform raising from
stow level or ground level to floor
level (fully-raised) position when
the UP switch is pressed. When
the lift is fully lowered, press-
ing the UP switch first raises the
outer barrier.
Note: The lift platform will not
raise if the outer barriers are not
in the upright (vertical) position.
This is a built in safety feature.
Stow Level: Stow level is the
height that the platform and car-
riage assembly moves in and
moves out of the lift housing.
Floor Level: Floor level is the
height that the platform and car-
riage assembly raises to in order
for the wheelchair passenger to
enter and exit the vehicle (fully
raised position).

Operation Notes and Details
NUVL “Public Use” lift models are
specifically designed to be oper-
ated by an attendant. The Lift
Operating Instructions contained
in this manual and appearing on
the lift operating instructions decal
provide instructions for operation
of the lift only. Read and become
familiar with all lift operation safety
precautions, operation notes and
details, operating instructions and
manual operating instructions
before attempting lift operation
procedures.
Lift Access Doors and Inter-
locks: Attendants must become
familiar with the vehicle lift access
door system and vehicle interlock
system(s). Transit vehicles and
lift access door configurations
vary. Door securement devices
(latches, hooks, cables, etc.) and
procedures to operate them vary.
Instructions for operation of ve-
hicle interlocks and door secure-
ment systems are not addressed
in this manual or on lift-posted op-
erating instructions decals due to
the variety of procedures required
for operating them. Braun Cor-
poration NUVL Series lifts comply
fully with all NHTSA vehicle and lift
interlock specifications (detailed
on pages 7 and 34). Infringement
of any lift interlock will prohibit lift
operation.
It is the responsibility of the lift
operator (attendant) to properly
open, secure and close the vehicle
lift door(s), to activate the vehicle
interlock(s), to load and unload the
wheelchair passenger (or standee)
on and off the lift platform, and to
properly activate all lift functions.
W
ARNING
Read and become
familiar with all lift
operation safety
precautions, opera-
tion notes and details,
operating instructions
and manual operat-
ing instructions prior
to operating the lift.
If this information is
not fully understood,
contact The Braun
Corporation immedi-
ately. Failure to do so
may result in serious
bodily injury and/or

Operation Notes and Details
Inner Roll Stop: The NUV-
L855RM24 is equipped with an
automatic inner roll stop that also
serves as a bridge plate. The
spring loaded inner roll stop auto-
matically deploys (rotates) to the
vertical position when the platform
extends from the stow position.
When the UP switch is pressed
and the platform raises to floor
level, this mechanical roll stop
is automatically rotated to the
bridging (horizontal) position to
provide a bridge plate between
the platform and the vehicle floor.
The inner roll stop must rest sol-
idly on the vehicle floor (minimum
1½" overlap). The roll stop auto-
matically deploys (rotates) to the
vertical (roll stop) position as the
platform lowers (DOWN switch is
pressed).
Inner Roll Stop

Page 18
Operation Notes and Details
The inner roll stop automatically
folds down to the platform sur-
face (horizontal) during the stow
function (as platform retracts).
Interlock Feature: The inner roll
stop senses weight (pressure) to
prohibit lift operation. The lift will
not function if the inner roll stop
is occupied.
Discontinue lift operation immedi-
ately if the inner roll stop does not
operate properly.
Outer Barrier: The two-stage
outer barrier provides a ramp for
wheelchair loading and unload-
ing at ground level (see photos
on following page). When the
platform lowers fully to ground
level, the electric actuator unfolds
(rotates) the barriers to the ramp
position (fully unfolded).
The tall outer barrier is spring
loaded but driven by the electric
actuator-powered short outer bar-
rier to rotate from the ramp (hori-
zontal) position to the deployed
(vertical) position.
Note: The tall outer barrier must
be manually raised and lowered

from the platform surface when
extending and retracting the
platform. Details are provided on
pages 20 and 21.
Although the outer barriers are
lift-powered, the activation of the
barriers are controlled by the lift
operator (attendant). Pressing
the DOWN switch unfolds the
barriers. The actuator-powered
two-stage outer barriers fold (ro-
tate) to the vertical position when
the UP switch is pressed.
Interlock Features: The outer
barriers sense weight to pro-
hibit lift operation. The lift will not
function if the outer barriers are
occupied. Lift platform move-
ment shall be interrupted unless
the outer barrier is fully deployed
(up).
