ELEVATOR, DUMB WAITER, WHEELCHAIR AND PLATFORM LIFT
INSPECTION, TESTING, AND MAINTENANCE MINIMUM REQUIREMENTS
Monthly
| 1 |
| Controllers: Inspect all devices for proper operation including but not limited to contacts. Relay contacts should not be burned or worn, and relay fingers should not be spread. Contacts should have minimum wear and have adequate contact pressure. |
| 2 |
| Pits: Check run-by, buffer, compensating, and emergency stop switches; ensure that their operation complies with Code requirements. Clean ironwork, sweep floors, remove trash, empty and clean drip pans, and remove grease and oils spots and drips. Clean oil return screens. Internal float switch of the oil return system should not allow oil to overflow onto the floor. External float switch of the oil return system should not allow water to leak into the oil reservoir. |
| 3 |
| Motors and Pumps: Where appropriate, check the condition and check for excessive heat, noise, and oil leaks. Lubricate per manufacturer’s instructions. Check brush spring tension and ensure that brushes are moving freely in brush holders. Inspect commutator and clean. Clean end bells and brush riggings with a blower or vacuum. Check oil. Belts should have no more than 3/16 inch vertical displacement. Belts should not bottom out in sheaves. Multiple belts should be replaced in a complete set. Belts should not be excessively worn, deteriorated, or oil saturated. Sheaves should not be excessively worn and should be aligned with one another. Check shaft and coupling fits/connections. Lubricate all bearings. Pumps/Motors/bearings should not make any howling or grinding noises. |
| 4 |
| Hydraulic Jacks: Inspect seals and packing, check alignment, and look for oil leaks. Clean packing head of dirt and debris. |
| 5 |
| Emergency Devices: Ensure that required emergency procedure signs and inspection certificates are installed. Check top and/or side exits; ensure that they and their safety switches operate. Test alarm bell, emergency stop switch, car emergency lighting, and communication systems. Where installed, test other emergency recall systems such as: Fireman’s recall service (key capture and/or smoke detector) for operation. |
| 6 |
| Car and Hoistway Doors: Inspect, clean, and lubricate all door operating mechanisms. Check all timing devices for operation, and adjust: check upthrust and pick-up rollers, door relation devices, interlocks, gear boxes, clutches, cables, proximity and/or photoelectric safety edges, door-open button, gibs, sills, door guides, normal-close speed, force-close speed, and self-close action. Clean car and hoistway sill grooves. |
| 7 |
| Pump Rooms: Check and adjust fluid levels (Complete Leak down Log as required per C.5.4.2.2.1). Clean control cabinets, sweep floors, and remove trash. Empty and clean drip pans. Clean oil return screens. Remove grease, oil spots, and drips from surfaces. |
| 8 |
| Lighting: Replace failed lamps in dispatch panels, car and hall push buttons, position indicators, direction indicators, car interior, pump rooms, and pits. |
Quarterly
| 1 |
| Car Guides: Inspect guides and guide shoes. Clean and lubricate. |
| 2 |
| Car Tops: Clean and lubricate car ventilating fans. |
| 3 |
| Controls: Inspect circuits and other devices for cleanliness and any evidence of overheating or general deterioration. Ensure that such devices are fastened to their frames or panels. Make required performance tests. |
| 4 |
| Leveling: Observe condition and operation of all leveling devices. Clean switches, discs, vanes, etc., and make necessary adjustments to ensure proper operation. |
Semi-Annual
| 1 |
| At the Semi-annual ITM occurring between Annual ITM, the contractor shall coordinate and contract with, on behalf of ERDC, the state of Mississippi approved inspection service, currently Bureau Veritas-National Elevator Inspection Services, INC., for periodic inspection of all lift systems listed in this contract. (See section C.5.6) |
| 2 |
| Motors: Inspect electrical connections for soundness. Check armature and rotor clearances. |
| 3 |
| Jacks: Inspect jacks for leaks and signs of excessive wear. |
Annual
| 1 |
| Perform annual tests required by the latest edition of ANSI A17.1 Code. Furnish a copy of test reports to the COR. Coordinate and contract with, on behalf of ERDC, the state of Mississippi approved inspection service, currently Bureau Veritas-National Elevator Inspection Services, INC., for CAT 1 Test Witnessing/annual inspection of all lift systems listed in this contract. (See section C.5.6) |
| 2 |
| Safety Mechanisms: Inspect, clean, lubricate, and manually operate. Terminal stop devices must slow down and stop the car at or near the terminal landing. Firefighter’s Service must cause the car to return to the designated fire service floor and park with doors open until the firefighter’s service is canceled. |
| 3 |
| Buffers: Inspect parts; adjust oil level. Manually compress buffer and ensure that proper return action is present. |
| 4 |
| Controllers: Check controls, wiring, connections, and fuses. Check that wire boards or switch panels are securely fastened to their frames. |
| 5 |
| Hydraulic Piping and Jacks: Check condition and look for leaks. Burrs, pitting, and gouges in cylinder(s) must be noted if present. Car must not drift. |
| 6 |
| Limit Switches: Check action of slow down, directional and final limit switches; adjust. |
| 7 |
| With a blower or vacuum, dust all surfaces in the hoistway including: top, bottom, and sides of cars; divider beams and brackets; car, rails, frames, and related ironwork; and hoistway walls. Remove grease or oil spots and drips from surfaces. |
| 8 |
| Door Closing Force: Check amount of force required to prevent door(s) from closing (Must not exceed 30 lbf). |
| 9 |
| Pressure Relief Valve: Must have specified bypass pressure when relief valve trips. Must be resealed if the setting is changed. |
| 10 |
| Flexible Hose & Fitting Assemblies: Must sustain a pressure test for 30 seconds without the hose leaking, bulging, distorting, or hose fittings slipping. Must be marked with the date of last replacement. Must be replaced at least every six years. |
| 11 |
| Pressure Switch: Must inhibit the operation of the lowering valves in the event there is not a positive pressure on the top of the cylinder. Must open when car stops on the pit buffer. |
