PART 2 EQUIPMENT

This section covers the supply and installation of one inclined wheelchair lift system. [Optional equipment and features are printed in italics, and are extra cost]

2.01 MODEL TYPE: Garaventa Stair-Lift Model XPRESS II: an inclined wheelchair platform lift that travels on two extruded aluminum rails along the edge of the stairway, installed either indoor or outdoor, to serve one flight of stairs, with two landings and two stops, with storage as described below.

2.02 PLATFORM TYPE:

1. Platform and ramps to be folded and unfolded electrically from the call station adjacent to the occupied landing.
2. Platform Size. Standard width is 800mm (31.5"). Two platform lengths are available:
   1. "1000" Platform (39.4" long)
   2. "1220" Platform (48" long)
   3. Add 185mm (7.3") to each end for platform ramps.
3. Platform to be rated for a load of 225kg (495 lbs.), with minimum 5X safety factor.
4. Non-slip surfaces on the deck and ramps.
5. Ramps are 152mm (6") high when folded up to prevent accidental wheelchair roll-off.
1. Sidewall, 175mm (6.9") high, also functions as vandal resistant cover to protect platform control switches when in folded position.
2. Clearances. When folded, the platform should not protrude more than 260mm (10.2") from the mounting surface. When unfolded and in use, it should not protrude more than 1020 mm (40.2") from the mounting surface for a unit without a sideload ramp and 1175 mm (46.2") for a unit with a sideload ramp (based upon direct mount to attachment wall - add 65mm (2.6") if self-supporting towers are used to support the system).
3. Platform to travel at a speed of 4m (13 ft) per minute.
4. Platform to have travel safeties that will cause the lift to stop if an obstruction, causing four pounds of pressure, is met. Two main sensing devices will cause the platform to stop: a Touch-Sensitive Plate under the platform and Multi-Directional Touch-Sensitive Ramps, which operate from both the inside and outside of the platform surface. When traveling in either the folded or unfolded position, contacting the ramp plates will automatically stop the lift. The lift must be capable of "backing away" from any obstruction encountered without the requirement to first clear the obstruction. This important feature ensures that an independent operator can return safely to an unobstructed landing.
5. Fold-down Seat, with a safety belt, to be provided on the platform (optional).
6. Wrap-around safety arms, to be provided at both ends of the platform (optional).

2.03 OPERATING CONTROLS - 24 Volts dc

A. Platform:

1. Key switch, constant pressure directional buttons, emergency stop switch and plug-in extension control for passenger or attendant operation. Platform ramps and platform underside equipped with obstruction sensitive cut-off safeties. Ramps and arms (if so equipped) must cycle automatically when the directional control switch is released at the desired landing.

B. Call Station at each landing:

1. Key switch, constant pressure platform call control.
2. One Touch Control System to automatically fold/unfold the platform and access ramps.
3. One Touch Control System to automatically fold/unfold the platform, access ramps and wrap-around safety arms (optional).

2.04 DRIVE SYSTEM

1. Motor to be .75 HP, 208-240 VAC, controlled by a frequency inverter and positioned within the conveyance.
2. Power Transmission: Worm gear reduction to a pinion moving on a fixed gear rack.

1. Rail System: Main Upper Rail: Bronze anodized aluminum extrusion weighing 8 lbs. per foot, with integrally mounted zinc plated gear rack. Lower Rail: 1.5" x 2.5" bronze anodized aluminum extrusion.
2. Overspeed governor and brake on upper carriage drive, containing mechanical overspeed sensor and lock, with electrical drive cut-out protection.

2.06 AUTOFOLD

This option will automatically fold the platform into the storage position if left unused in the open position at a landing for a period of 1-10 minutes (field adjustable).

2.07 FOLD FROM OTHER CALL STATION

This option allows the platform to be folded into the storage position from the opposite call station.

2.08 AUDIO VISUAL ALERT

· _______ Audio-visual Alert(s) to be installed in the stairway. Alert units must be wall mounted in sufficient numbers to be visible from all flights and landings whenever the platform is operating in the stairway in either the folded or unfolded position. (May be required by local building authorities in some situations.)

2.09 FIRE SERVICE

Fire Service to be provided, to ensure that the lift is not used for emergency egress and that it does not impede stairway traffic. When the building fire alarm system is activated, the lift will not operate if the platform is folded and the key is turned off. If the lift is in use when the fire alarm is activated, it will travel only in one direction – toward the landing that has been designated as the emergency exit. This feature is programmable in the field. This feature includes the circuitry and connections within the lift system only; connections from the lift system to the building alarm system and any alterations to the building alarm system required to accommodate this feature are the work of other trades and are specifically excluded from this section. (May be required by local building/fire authorities in some situations.)

2.10 EMERGENCY EVACUATION DEVICE

· Supply ___ emergency evacuation devices housed in steel storage cabinets located adjacent to each Stair-Lift landing floor above ground level. To fully comply with the following specifications:

TYPE: Garaventa "Evacu-Trac"

CAPACITY: 1 person, 163 kg (360 lbs.) with minimum 1.5 times safety factor.

MAXIMUM STAIR ANGLE: 40 degrees.

SPEED GOVERNOR: Piston brake.
