1. Working Hours a. Scheduled elevator maintenance is to be performed during regular working hours of IUEC regular working days, hereby designated as 7:00 A.M. to 3:30 P.M. Monday-Friday. b. Callback service during regular working hours is included in Complete Maintenance. c. Scheduled escalator maintenance shall also be performed during regular working hours. 2. General a. If deficiencies are observed during the examination and testing of the elevators, Contractor shall proceed immediately with corrective action except for 4.26 Excluded Work. b. Complete Maintenance - The following listing of Elevator Maintenance Tasks is required and applies to elevators on Complete Maintenance. It is not intended to be all inclusive, and Contractor recognizes that numerous additional services are required per good industry standards and practices, and in order to comply with elevator Code requirements and Performance Standards as listed in Attachment B. c. The minimum frequency is indicated in parenthesis. Your MCP may designate shorter inspection frequencies for various elevators due to conditions indicated in Section 4.25 C & D. d. Examination and Lubrication service - For conveyances on Examination and Lubrication service, this section shall not require parts replacement unless otherwise required in Section 3, nor more frequent inspections than the minimum frequency listed on the maintenance pricing page dictates. Contractor shall work in the general maintenance tasks and procedures at reasonable intervals considering the minimum inspection frequency listed on the maintenance pricing page. Quarterly checks of Firefighters' service operation are included with Examination and Lubrication service. 3. Elevator Maintenance Tasks (Minimum CM Frequency in parentheses) a. General Maintenance Procedures i. At the prescribed minimum frequency (time interval), ride each elevator and perform a general safety inspection, checking initial floor stops in both directions of travel, brake operation (if applicable), releveling, door operation, ride quality, and make adjustments as required for consistent and smooth operation. (Each inspection) ii. At the prescribed minimum frequency (time interval), inspect signal fixtures, including position indicators, call registration pushbuttons, car or hall lanterns, and the operation of all accessibility devices required by ICC/ANSI A117.1, SPS 69, ADAAG 4.10, and ADAAG 4.13. Make adjustments, repairs, replacements or other corrections. (Each inspection) iii. Firefighters’ service operation shall be exercised quarterly on all applicable units and the findings documented in the machine room or control room. (Quarterly) b. Machine Rooms - Maintain elevator machine rooms, including controllers and drives, machines, motors, motor generators, brakes, suspension ropes, drive and secondary sheaves, sheave liners, selectors and tapes or ropes, and governors. i. Proactively examine traction machines for unusual sounds, heat, or improper operation, and make corrections. Maintain, lubricate, and renew bearings, worms, gears, gearboxes and reduction units, coupling pins and bushings, drive sheaves and sheave cable grooves, cable sheave liners, lubricating chains, machine brake, rope gripper, or other emergency brake. Check oil levels, repair leaks, empty drip pans, lubricate bearings, replace seals and gaskets as required. (Semiannual) ii. Verify proper oil level in machine. Drain, flush, clean, and replace machine gear case oil at three year intervals or otherwise at manufacturer’s recommended intervals if containing synthetic oil. (Annual) iii. Motors and motor generators shall have resistance periodically measured and recorded. Blow out or otherwise clean to remove carbon dust, and renew or maintain insulation resistance at minimum 2 meg ohms. For readings < .5 meg ohms, armature or other components shall be steam cleaned, baked, and reinsulated. All armatures and windings, field coils and interpoles, bearings, rotating elements, commutators, filters, fans, blowers, brushes, and brush holders shall be cleaned and renewed or rewound as required. Rotating parts shall be properly aligned within the manufacturer’s design tolerances. (Annual) iv. Machine brakes shall be inspected, cleaned, lubricated, adjusted, tested, or otherwise renewed. DC brake solenoids shall be disassembled, inspected, cleaned, lubricated, adjusted on an annual basis at a minimum, and documented in the maintenance record. Observe operation frequently for proper stopping accuracy in both up and down directions. Clean, inspect, and renew brake cores, sleeves or core liners, coils, pivot pins, solenoids, brake switch, springs, brake switch, and shoe linings. (Annual) All machine brakes shall be tested to safely lower, stop, and hold the elevator car with a 125% capacity load at the time of each Category 5 test, at a minimum. v. Maintain controllers, selectors, and dispatching equipment per equipment manufacturer’s specifications, renew worn or defective components. Disassemble, clean, and adjust power contactors and other relays or components, and proactively replace worn, burned, or defective contacts, shunts or leads, arc shields, fuses, relays, coils, springs, cams, resistors, switches, transformers, transducers, condensers, power supplies, amplifiers, dashpots, timing devices, overloads, rectifiers, wiring, printed circuit boards and connectors, other solid state or electronic components, or any other devices as required. Severe arcing shall be corrected. Temporary wiring shall not be used. Renew all controller fans and air filters. Clean controller cabinet, install covers. Replacements for all fuses and controller contacts shall be available in the machine room or company vehicle. (Bimonthly) vi. Batteries for emergency lighting, emergency lowering, telephone, processors, or other batteries shall be examined and inspected, circuits tested and charger output recorded. Maintain and renew batteries, battery chargers, monitors, and all other components as required. (Quarterly) vii. Verify the operation of group or supervisory systems and make adjustments as required at intervals to insure all circuits and settings are properly adjusted to minimize control system response time for car and hall calls. (Semiannual) viii. Machine and control rooms shall be kept clean, floors painted as needed, and trash and debris removed. All covers and labeling shall be in place. Replacement parts shall be provided and organized. (Semiannual) ix. Callback service and repairs necessary during regular working hours should the elevators fail to function properly after Agency’s testing of emergency power systems, is included at no additional cost. (Upon request) x. Devices for ascending car overspeed and unintended car movement protection where provided shall be maintained, renewed and periodically tested. (Annual) xi. Maintain or renew hydraulic power units and components, including control valves and manifolds, O-rings and gaskets, strainers, springs, pumps, motors, V-belts, mufflers and sound isolation couplings, hoses, shutoff valves, pipe or pressure line and fittings, power unit reservoir, etc. for proper operation and to prevent leakage, which shall not be permitted to accumulate. (Semiannual) xii. Contractor shall monitor and maintain the hydraulic fluid level in the power unit reservoir (Quarterly). Contractor and shall immediately investigate and correct any loss of hydraulic fluid. Loss of hydraulic fluid that cannot be accounted for shall result in Contractor removing the equipment from service and promptly conducting leak down and pressure tests as specified in ASME A17.1-2016, Req 8.11.3.2 at no additional cost to Dane County for Complete Maintenance only.
