About this file

This file is a Performance Work Statement (PWS) checklist for preventive maintenance of electric elevators at Fort Huachuca under the Directorate of Public Works. The checklist serves as the inspection and testing protocol that contractors must follow during each preventive maintenance visit, structured according to ASME A17.1 standards for elevator safety and compliance.

The checklist encompasses comprehensive inspections across six major elevator system areas: inside car inspections (door reopening devices, stop switches, operating controls, lighting, emergency signals, doors, flooring, ventilation, and safety systems); machine/control room/space inspections (equipment exposure, access, lighting, ventilation, fire extinguishers, guarding, and machinery components including drive machines, sheaves, ropes, governors, and brakes); top-of-car inspections (stop switches, operating devices, counterweight clearance, terminal stopping devices, broken rope switches, leveling devices, hoistway construction, guide rails, and wire rope fastening); outside hoistway inspections (hoistway doors, locking devices, vision panels, and parking devices); pit inspections (access, buffers, terminal devices, traveling cables, compensating systems, and machinery supports); and firefighters' emergency operations. The checklist requires contractors to document pass/fail/not applicable status for each inspection item, building information, unit identification, mechanic credentials, and test date. Specific technical criteria are provided for wire rope replacement based on ASME standards, including different thresholds for 6x19 and 8x19 class ropes with varying broken wire limits depending on distribution patterns and wear conditions.

- Wire suspension and compensating ropes shall be replaced

(a) if the broken wires are equally distributed per rope lay in the worst section of the rope exceeds the value shown in column A of table 8.11.2.1.3

(b) if the distribution of broken wires is unequal and broken wires predominate in one or two stands, when the number of broken wires per rope lay in the worst section of the rope exceeds the values shown in column B of Table 8.11.2.3 (cc)(1); or

(c) if four or five wires, side by side, are broken across the crown of any strand, when the number of broken wires per rope lay in the worst section of rope exceeds values shown in column C of Table 8.11.2.1.3 (cc)(1); or

(d) if in the judgment of the inspector, any unfavorable condition, such as fretting corrosion (red dust or rouge), excessive wear of individual wires in the strands, unequal tension, poor sheave grooves, etc., exists, the criteria for broken wires will be reduced by 50% of the values indicated in Table 8.11.2.1.3(cc) (1) for any of the three conditions described above; or

(e) if there is more than one valley break per rope lay.

- On winding drum machines, the ropes shall be replaced

(a) if the broken wires are equally distributed among the strands, when the number of broken wires per rope lay in the worst section of rope exceeds 12 to 18; or

(b) if wire breaks predominate in one or two strands, when the number of broken wires per rope lay in the worst section of rope exceeds 6 to 12; or

(c) if there is more than one valley break per rope lay.

- On any type of elevator, the suspension compensation and governor ropes shall be replaced when their actual diameter is reduced below the value shown in Table 8.11.2.1.3 (cc)(3).
