8.6.4 Maintenance and Testing of Electric Elevators
(a) Guide rails, except those of elevators equipped with roller or other types of guiding members not requiring lubrication, shall be kept lubricated.
(b) Where sliding-type safeties are used, the guide-rail lubricants, or prelubricated or impregnated guide shoe gibs, where used, shall be a type recommended by the manufacturer of the safety (see 188.8.131.52.2 and 2.17.16).
(a) The oil level shall be maintained at the level indicated by the manufacturer. The grade of oil to be used shall be as indicated on the buffer marking plate, where required (see 184.108.40.206 and 220.127.116.11).
(c) Buffer oil shall not be stored in the pit or hoistway or on top of the car.
(a) residual pads (antimagnetic pads)
(b) lining and running clearances
(c) pins and levers
(e) sleeves and guide bushings
(f) disks and drums
(g) brake coil and plunger
(a) 1 yr, for machines located over the hoistway.
(b) 2 yr, for machines located below or at the side of the hoistway.
(c) where auxiliary rope-fastening devices conforming to 2.20.10 are installed, refastening at the periods specified is not required, provided that, where such devices are installed, all hoisting ropes shall be refastened on the failure or indication of failure of any rope fastening.
(d) where the elevator is equipped with a drum counterweight, the fastenings shall be examined for fatigue or damage at the socket. Where fatigue or damage is detected, the ropes shall be refastened in conformance with 18.104.22.168.2.
(a) In resocketing babbitted rope sockets or replacing other types of fastenings, a sufficient length shall be cut from the end of the rope to remove damaged or fatigued portions. The fastenings shall conform to 2.20.9. Where the drum ends of the ropes extend beyond their clamps or sockets, means shall be provided to prevent the rope ends from coming out of the inside of the drum and to prevent interference with other parts of the machine.
(b) The suspension wire ropes shall conform to 2.20.7.
(a) the name of the person or firm who performed the resocketing or changing to other types of fastenings
(b) the date on which the rope was resocketed or other types of fastening changed
The material and marking of the tags shall conform to 22.214.171.124, except that the height of the letters and figures shall be not less than 1.5 mm (0.0625 in.).
(c) door reopening devices
(d) vision panels and grilles, where required
(e) hoistway door unlocking devices and escutcheons
(h) sills and bottom guides, fastenings, condition, and engagement
(i) clutches, engaging vanes, retiring cams, and engaging rollers
(j) interconnecting means
(k) door closers, where required
(l) means to restrict hoistway or car door opening and expiration date for the alternate power source, where required
126.96.36.199.2 Kinetic Energy and Force Limitation for Automatic Closing, Horizontal Sliding Car and Hoistway Doors or Gates
(a) Examinations. All working parts of car and counterweight safeties shall be examined to determine that they are in satisfactory operating condition and that they conform to the applicable requirements of 188.8.131.52 through 184.108.40.206 (see 2.17.10 and 2.17.11). Test the function and operation of the switch operated by the safety. Check the level of the oil in the oil buffer and the operation of the buffer compression switch on Type C safeties.
(b) Tests. Safeties shall be subjected to the following tests with no load in the car:
(1) Type A, Type B, or Type C governor-operated safeties shall be operated by manually tripping the governor with the car operating at the slowest operating speed in the down direction. The switch operated by the car safety mechanism shall, for the duration of the test, be temporarily rendered inoperative. If the governor is equipped with a switch that operates when the governor is manually tripped, it must be rendered inoperative. Where application of the emergency brake required by 2.19.3 occurs, the means to actuate the emergency brake, for the duration of the test, shall be temporarily disabled to prevent its assistance in stopping.
In this test, the safety shall bring the car to rest promptly.
In the case of Type B safeties, the stopping distance is not required to conform to 2.17.3.
In the case of Type C safeties, full oil buffer compression is not required.
In the case of Type A, Type B, or Type C safeties employing rollers or dogs for application of the safety, the rollers or dogs are not required to operate their full travel (Item 220.127.116.11).
(2) Governor-operated wood guide-rail safeties shall be tested by manually tripping the governor with the car at rest and moving the car in the down direction until it is brought to rest by the safety and the hoisting ropes slip on traction sheaves or become slack on winding-drum sheaves [Item 2.29.2(d)].
(3) Type A and wood guide-rail safeties without governors that are operated as a result of the breaking or slackening of the hoisting ropes shall be tested by obtaining the necessary slack rope to cause it to function (Item 18.104.22.168).
