Specifications include, but are not limited to: 1. Specific Equipment Performance Standards: a). Call-back: Normally four to possibly six per year, excluding nuisance calls. 2. Minimum expected periodic servicing, checking, oiling, and adjustments: a). Every 2 weeks: Ride the car, observing operation, adjust in tank with car at top. b). Every 13 weeks: Check adjustment of car doors and door operator, adjust if needed, check landing switches, check guide lubricators and lubricate. c). Every 26 weeks: Clean and examine Saf-T-Edge, door guides and fastenings. d). Every 52 weeks: Clean, oil and adjust all hoist-way doors, check all control switches, car and corridor stations. Check and make sure that all electrical connections are tight. e). Other: Every 5 years consideration should be given to the need for oil filtration or replacement. If it is dirty, change the oil, you are being paid to maintain the equipment. 3. Doors and Operation: Frequency of inspection and adjustment briefly covered above. a). Car and Hoist-way Doors: Clean and lubricate track and hangers as needed. Check backplate and hanger to door fastenings, relating devices to insure tightness. Check up-thrust adjustment and fastening (nominal 0.010” to track), should clearance exceed 0.035” it should be adjusted. Check tightness of relating devices. Door interlock adjustment to be set to permit the latch to drop within 3/8” or less of full closure. Check contact setting for pressure and contact wipe. Bottom door guides should be fastened tight and replaced when panel may be moved in and out by ¼” or more. Check and tighten non-vision wings/sight guards at each inspection. Final latch cam and spring adjustment to be set to fully close the doors to locking position when within 1” to 1 ½” of full closure. Car door contact should be set to prevent car movement unless door is 2” or less from full closure. b). Car door safety device should be checked quarterly for freedom of movement to permit it to operate with even a somewhat glancing blow, but not sloppy permitting it to rub against door. Where retractable projection is used at the opening, it should be slightly in front the door and should permit the door to be held in the open position with pressure on the edge, in closing, edge should permit door to reopen within 1-1/2” of full closure or less. Reopening action should be such that reversal of the door movement will occur at such a point or before the leading edge of the vane and doors are in the same plane. i.e. at or before the complete collapse of the edge. Active contact line of the edge should be free of cuts and bulges. Control contact cable and retracting cable, where used should be held clear of snagging on other moving parts. Maintain car door kinetic energy and door pressure within ASME A17.1 code requirements at all times. Electronic door detectors are to be set to fault to the open position. Maintain door nudging within ASME A17.1 code requirements. c). Door Operator: Check, lubricate, and adjust quarterly, where gear operators are used, gear oil level should be checked and the unit cleaned and flushed and refilled within five years. Opening motions should be at design speed smooth start, slowdown and stop, with particular care being taken to avoid drag in the opening action as the door reaches full open position. Closing time should be adjusted to comply with the current requirements on kinetic energy and smooth start and stop. Closing adjustment should permit door reversal within travel of the Saf-T-Edge as above without further drift.
