4.10 CABLE

Minimum of two 3/8" (10 mm) IWRC Galvanized Aircraft Cables. Minimum breaking strength of 14,400 lbs. each.

4.11 SAFETY DEVICE

A "slack/broken cable" safety device shall be supplied which will stop and sustain the elevator and its rated load, if either of the hoisting cables become slack or breaks. The safety device shall be resettable by the operation of the elevator in the upward direction. A switch shall be mounted in such a position as to sense the operation of the safety device, and will open the safety circuit to the controller to prevent operation of the elevator in either direction.

4.12 GUIDE YOKE

The 1:2 guide yoke/sheave arrangement shall be supplied with a sheave, guide shoes, roller bearings and adjustable cable guards. The sheave shall be finished with rounded grooves to fit the cables.

4.14 FINAL LIMIT SWITCH

The elevator shall be equipped with a final limit switch to cut off all power to the elevator if the upper normal terminal stopping devices fail.

4.15 GUIDE RAILS AND BRACKETS

4.15.1

Steel 8lb/ft "T" guide rails and brackets shall be securely fastened to the building structure.

4.15.2

Brackets shall securely hold the guides in a plumb and true position regardless of car loading.

4.15.3

Guides shall be bolted through the hoistway enclosure with back-up plates, washers and nuts. Subject to architects’ alterations and approval.

4.16 CAR SLING

4.16.1

Car sling shall be fabricated from steel members with adequate bracing to support the platform and cab.

4.16.2

The buffer-striking member on the underside of the car must stop the elevator before the jack plunger reaches its down limit of travel.

4.16.3

Guide shoes to be solid slipper type with polyurethane inserts.

4.17 WIRING

All wiring and electrical connections shall comply with applicable codes, insulated wiring shall have flame retardant and moisture proof outer covering and shall be run in conduit or electrical wireways. Traveling cables shall be flexible and suitably suspended to relieve strain.

Part 5 - EXECUTION

5.1 EXAMINATION

All site dimensions shall be taken to ensure that tolerances and clearances have been maintained and meet local regulations.

5.2 PREPARATION

Pre-inspect the construction and service requirements for "Work by Others". These requirements will be included in drawings, diagrams, engineering data sheets and special instructions before the work commences.

Rail Orientation to Support Wall

R1 = 304 LBF

R2 = 194 LBF

Rail reactions do not include safety factors. Applicable safety factors must be considered in hoistway design.
