| General Requirements Requirements for installation vary by type of equipment selected. These
general requirements will serve as a guide to assist you in preparing your building for
the installation of Schindler elevators.
All designs, clearances, construction, work-manship and materials,
unless specifically excepted, shall be in accordance with the requirements of the ASME
A17.1 or CAN/CSA-B44 Code plus applicable Building Code. For specific rules, refer to ASME
A17.1 Parts I and II or CAN/CSA-B44 Sections 1, 2 and 3 for traction elevators. Local
requirements must be used if more stringent.
Items To Be Provided
To complete the installation, the following items must be
considered, which are not included in the elevator contract:
Hoistway
1. Clear, plumb hoistway, with variations not to exceed 1"
(25mm) at any point. Two-hour fire resistance rating of hoistway walls or rating to meet
applicable local codes.
2. 750 bevel guards on all projections, recesses or
setbacks over 2" (51mm) ASME A17.1 or 100mm CAN/CSA-B44 except on side used for
loading or unloading.
3. Number of cars in hoistway, minimum size of cars, venting and
fire rating of doors and entrances must be specified per applicable Building Code.
4. Maximum allowable vertical spacing of rail supports to be 16'
(4877mm). Divider beams between hoistway at each floor, and under machine room floor, for
guide rail bracket supports.
5. Lighting for each elevator machine room, as indicated by elevator
contractor.
6. Recesses, support and patching, as required to accommodate hall
button boxes, signal fixtures, etc.
7. All barricades either outside elevator hoistways or between
elevators inside hoistways as required.
8. Dry pit reinforced to sustain normal vertical forces from rails
and buffers. Consult Schindler sales representative for rail forces and buffer impacts.
Where there is space below the pit floor which can be occupied, a counterweight safety is
required. Consult your elevator contractor for incremental hoistway dimensions.Buffer
inspection ladders and platforms if required.
9. Convenience outlet and light fixture in pit with switch located
adjacent to access door per ASME A17.1 Rule 1061e and CAN/CSA-B44 2.7.5.
10. Where access to pit is by means of lowest hoistway entrance,
vertical ladder of non-combustible material extending 42" (1070mm) minimum above sill
of access door or handgrips shall be provided to the same height.
11. Entrance wall and finished floor are not to be constructed until
after door frames and sills are in place.
a. where front walls are of reinforced concrete,
the concrete openings must be minimum 12" (300mm) wider than the outside trim of door
frames and 6" (150mm) higher than head trim.
b. Where drywall or sheet rock construction is
used for front walls, it shall be of sufficient strength to maintain the doors in true
lateral alignment. Drywall contractor to coordinate with the elevator contractor. Note : A
support member (spreader beam) must be provided for floor heights greater than 12'-0"
(3658mm) to support entrance header struts.
c. Door frames are to be anchored to walls and
properly grouted in place to maintain legal fire rating (masonry construction).
12. Furnishing, installing and maintaining the required fire rating
of elevator hoistway walls, including the penetration of fire wall by elevator fixture
boxes, is not the responsibility of the elevator contractor.
13. The interface of the elevator wall with the
hoistway entrance assembly shall be in strict compliance with the elevator contractor's
requirements.
14. For applications requiring grouted sills, provide sill supports
with 21/2"x4" (65mm x 102 mm) minimum floor recess the
full width of the hoistway. Grout full length and width after sills are set.
15. When sill angles are provided by the elevator manufacturer,
hoistway should be capable of accepting stud type fasteners and supporting loads imposed
based on loading of elevator.
Machine Room
16. Enclosed and protected machine room.
17. Access to machine room and machinery space as
required by governing code or authority.
18. Lighting, convenience outlets, heating, cooling and ventilation
of machine room and machinery space. Machine room temperature to be maintained between 55°
F and 90° F (13° C and 32° C). Relative humidity to be
maintained at 95% or less non-condensing.
19. A fused disconnect switch for each elevator and
light switch located per National Electrical Code, (NFPA No. 70), and where practicable,
located inside machine room adjacent to door.
20. Suitable copper feeder, ground and branch wiring circuits for
signal system and power operated door, including main line switch. Feeder and branch
wiring circuits for car light and fan, including main line switch. Ground fault protection
as required by NEC 620-85.
21. Reinforce concrete machine room floor slab or grating, as
specified, which must not be placed over the hoistway until elevator machinery is set in
position.
22. Hoisting beams, trap doors, ladders or stairs and other means of
access to machine room of maintenance and equipment removal purposes.
23. Supports for machine and sheave beams including wall pockets and
patching after beams are set in place. Beams for machine and sheave will be mounted on top
of building supports. Consult elevator contractor and elevator shop drawings for overhead
reactions and elevation of supports.
24. Convenience outlet and telephone outlet on control panel.
25. All conduit and wire runs remote from either the machine room or
the hoistways.
26. Heat, smoke or products of combustion sensing devices connected
to elevator machine room terminals when such devices are required.
27. Architectural precautionary measures to
provide sufficient attenuation for rooms near the machine room in which air borne noise
produced by the elevator system would be inconvenient.
Emergency Provisions
28. Elevator Firefighter's Service is required per ASME A17.1 Rule
211.3 and may be required per CAN/CSA-B44 3.12.15.1.1. Elevator Firefighter's Service
wiring and inter-connections to automatic sprinkler systems or heat and smoke sensing
devices furnished by others. Emergency services may be required by Building Code.
29. When emergency/standby power operation of elevators is required,
the Electrical Contractor should coordinate with your elevator contractor for operation
requirements.
30. Provisions for earthquake protection, dictated by the Building
Codes, may be required. Consult your elevator contractor special requirements. |
