Lift Terminology

Introduction:

Braun NL Millennium Series lifts are ADA compliant and comply fully with National

+LJKZD\7UDIÀF6DIHW\$GPLQLVWUDWLRQ1+76$VSHFLÀFDWLRQV

The NL is commercial oriented (intended for operation by an attendant).

Lift models vary per size (lift model numbers indicate lift dimensions). NL 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 (NL917IB). Right side pump lift models are a mirrored image of rear pump models

(pump module located on opposite end of base plate).

Refer to the Lift Terminology

,OOXVWUDWLRQIRULGHQWLÀFDWLRQRI

lift components.

Lift operation procedures are identical for all NL 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.

Terminology: Become familiar with the terminology that will be used throughout this manual. Become familiar with the

LGHQWLÀFDWLRQRIOLIWFRPSRQHQWV

and their functions. Contact your lift sales representative or call The Braun Corporation at

1-800-THE LIFT

if any of this information is not fully understood.

Direction: The terms "left," "right," "inboard," and "outboard" will be used throughout this manual to indicate direction (as viewed from outside the vehicle looking directly at the lift). Refer to the Lift TermiQRORJ\,OOXVWUDWLRQVIRUFODULÀFDtion of direction terms.

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 platform assembly consists of the steel tubing frame with grating surface upon which the wheelchair is positioned, the outer barrier, outer barrier latch, the inner roll stop, and the hydraulic cylinder assembly that powers 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 cylinderpowered automatic outer barrier provides a ramp for wheelchair loading and unloading at ground level. Photos and further details regarding the outer barrier are provided in the Operation Notes section (pages 19-21).

Outer Barrier Latch: The springloaded latch locks the outer barrier in the vertical position when the platform raises above ground level.

Lift Terminology

Inner Roll Stop: NL 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 and the

YHKLFOHÁRRU7KHLQQHUUROOVWRS

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 NL917IB Series lifts comply fully with all NHTSA vehicle and lift interlock VSHFLÀFDWLRQV9HKLFOHPRYHment is prohibited unless the lift is fully stowed and the lift will not function unless the vehicle is parked and secured.

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

PRUH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

the 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 and the outer barrier latch is positively engaged.
