Maintenance and Inspection
Maintenance and Inspection
This domain tests the routine work that keeps equipment code-compliant and the inspection process that verifies it. Maintenance is not just lubrication: it includes brake adjustment, rope and sheave inspection, door operation, hydraulic oil condition, and records that show the work was done. Inspections follow ASME A17.2 and the Illinois-adopted rules.
Maintenance essentials
- Follow the manufacturer's maintenance schedule and record each visit, task, and deficiency.
- Check brake lining wear, drum and sheave condition, rope broken wires, rope diameter, and equalization.
- Verify door closing force, reopening device, interlock operation, and clearance.
- For hydraulic units, check oil level, relief-valve setting, jack packing, and rupture valve.
Inspection process
- Annual inspections verify code compliance and support the operating certificate. Critical defects require the unit to be taken out of service until corrected.
- A17.2 inspection items include machine room, hoistway, car, pit, safeties, buffers, and electrical equipment.
- Reinspection confirms corrections; documentation should identify the code edition and the item inspected.
Worked example
During an annual inspection, a car moves with its door open about 2 in. The interlock is not preventing operation. Reasoning: the door interlock must prevent car motion unless the door is closed and locked. This is a critical safety defect, so the car is removed from service and the interlock is repaired and retested. Recording "adjusted door" without verifying the interlock does not close the item.
Traps
Signing off maintenance without testing devices; confusing a routine service call with an annual inspection; failing to document code edition and deficiency; and returning a car to service before a critical defect is corrected.
