with building structure, having shelf-angles at each side, tie-down bolts, ancillary bed-plates, metal flooring and overhead support stands, as needed. Provide bearing plates and anchors, as required to secure machine beams to the structural supports.

2. Where structural drawings do not show a floor slab immediately on top of the hoistway, provide suitable solid-metal flooring to meet requirements of all governing authorities, having a non-slip steel checker-plate surface or resilient vinyl over a metal floor.

B. Ground all non-conducting metal parts, including controller cabinets. C. Provide metal and angle iron guards at all floor openings to protect against

accidental contact with moving rope.

2 02 CONTROLLER A. Provide a sheet metal cabinet with removable hinged doors (key-locked) and

with filtered ventilation sufficient to maintain interior temperature at a reasonable level. Position the controller cabinets securely on self-supporting steel frames, so the lowest operating part is more than 150 mm above the floor.

B. Use relays only for safety, dispatcher backup and power circuits. Design relays for electrical and mechanical life equivalent to 30-years of operation. Design the contacts with a wiping action to ensure maximal conductivity.

C. Use microprocessors for all logic functions (motion control, dispatch, car control, etc.). Use crystal-regulated frequencies. Provide dispatch programs in EPROM with at least 25-percent spare capacity. Power each processor by a separate power supply. Isolate inputs and outputs with optical devices or relays.

C. Automatically reset the simulated position at terminal landings when it is out of step relative to actual position.

2 04 GUIDE RAIL A. Provide standard T-section rail (hot-rolled structural steel) with guide surfaces

accurately planed or ground, and sufficiently precise tolerance for Class A rating. Overall length of each pair of rail stacks (car or counterweight) shall be equal. Total thickness variation of each running surface shall be less than 0.25 mm, measured from the base.

B. Fix rail brackets to building structure so no movement can occur. Through-bolt the rail bracket. Pin adjustable brackets after final alignment, with bolts and nuts.

C. Securely fasten the guide rail with suitable slip-clips and brackets. Rail slip-clips shall contain brass inserts and be properly secured (remain in position even if fastening bolts become loose). Place and support the guide rail to prevent distortion due to eccentric loading of the lift car, or application of a safety device.

D. Review structural drawings to verify the locations of rail supports through the hoistway. Size the guide rail for indicated spacing between successive supports, using suitable rail size (or rail-backing) to prevent deflection affecting ride quality. Advise the Consultant of any structural support deficiency, or install intermediate support as needed to provide the specified ride quality.

E. Align and plumb the guide rail with metallic shim (5-20 mm) between rail bracket and rail back. Shims to secure alignment and maintain orientation even if fastening bolts loosen.

F. Use steel splice plates at least 20 mm thick. Machine rail contact surface of splice plates and back of the guide rail to match joints at the rail face with riding surfaces in the same plane and all joints are closed. Provide at least four through-bolts per rail end (eight per fish-plate) Locate rail joints to not interfere with support brackets or divider beams. Do not cut, grind or otherwise modify divider beams (or structural beams).

G. Verify structural tolerance and hoistway plumb as within ± 25 mm at all formed walls. Use jack bolts so rail rests on and is attached to steel structure in the pit, spanning the car rails and the counterweight rails. Align car and counterweight rails so:

1. Distance between rail faces does not vary by more than 0.75 mm at any point, with cumulative variation less than 1.5 mm over any 30-meter length.


10

4. Protect machined surface with factory-applied coat of suitable corrosion protection (readily removable after rail installation). Protect non-machined surface with factory applied paint coat. Protect the guide rail against adverse weather throughout the construction period. Remove corrosion and re-paint non-machined areas prior to Final Acceptance testing. Corroded or damaged rail will not be accepted.

5. Arrange rail stack length to compensate for building compression (6 mm per 4 m) with from 150 to 300 mm top and bottom clearances. Use jack bolts at the bottom, and provide anti-snag guards to prevent fouling the rope or snagging traveling cable.

2 05 TERMINAL STOPPING DEVICES A. Provide normal terminal stopping devices (NTSD) to automatically and

exponentially slow and stop an elevator at top and bottom terminal landings, under any load other than overload, and from any speed attainable in normal operation. Design NTSD to function independently of normal stopping means, and independently of final terminal stopping devices (FTSD). Design NTSD to operate until the FTSD is actuated. NTSD designs that allow an elevator to enter the FTSD shall not be accepted, nor shall high-speed stops be considered equivalent to exponential slowdown.

B. Install slowdown and normal stopping devices on top of each elevator wholly enclosed in dust-proof steel casing. Arrange that, as an elevator approaches a terminal landing, the device causes a roller (noiseless tread mounted on a moveable arm) to contact a cam in the shaft and operate a stop mechanism that (automatically) brings the car to a smooth stop at the terminal landing. Arrange the entire width of roller tread to engage the cam.

B. Provide FTSD to automatically stop an elevator (car and counterweight) within top and bottom over-travel spaces, independently of buffers and NTSD. Through-bolt or dowel the final limit switch brackets, after adjusting an elevator but prior to doing safety tests for the Inspecting Authorities.
