Escalator annual maintenance checklist

Owner told the escalator will be out of service

Owner and building staff told when the unit stops and for how long, with the alternate route signed so riders are not left looking for a way between floors.

Both landings closed off before any plate is lifted

Full barricades and out-of-service signs at the top and bottom set before the mechanic lifts a landing plate or removes a step, kept in place until the unit is released.

Step, skirt and comb safety devices observed during the contractor's test

Skirt-obstruction, missing-step, comb-impact and handrail-entry devices exercised by the contractor and seen stopping the unit, results noted against what the contractor records.

Broken-step-chain and speed governor checks observed

Contractor's checks of the step chain and overspeed governor witnessed, the unit seen shutting down on the intended fault rather than assumed.

Step-to-skirt clearance measured along both sides

Mechanic's gauge run down both skirts with the unit stopped, clearance within the manufacturer's range at every point, a measured value beyond the quarterly look.

Handrail and step speeds measured by the mechanic

Each handrail's speed read against the step speed on the mechanic's tachometer, within the manufacturer's tolerance and recorded, not judged by eye as on the quarterly round.

Brake stopping distance measured and compared with last year

Mechanic's measured stop from rated speed with the steps empty, within the manufacturer's range and set against last year's recorded distance.

Mechanic's lock and tag observed before the machine space is entered

Lock and tag on the main disconnect and every other source feeding the drive and controller, hung by the mechanic under the site's procedure and verified dead before hands go in.

Pit and truss interior housekeeping observed

Pit and step-band area free of accumulated lint, debris and lost items, no oil pooling under the drive, access panels refitted after the contractor's work.

Machine space, drive and lighting observed

Drive machine and controller free of leaks or scorching, machine-space lighting and the stop switch functional, nothing stored in the space.

Drive train and step rollers observed from the machine space

Drive chain or gear train lubricated per the manufacturer with no dry or stretched links reported, step rollers seen through the opening with no flat spots or cracked tires.

Controller seen with no jumper or bypass left before release

Mechanic shows every jumper, bypass switch and test link removed or back to normal at the controller, and the safety circuit closed, before the unit is released.

Plates refitted and the unit run before the barricades come down

Landing plates flush and fastened, combs meshing, locks removed by the mechanic who hung them, unit run empty in both directions before riders are let back on.

Contractor findings and open items recorded on the building side

Any deficiency the contractor calls out logged with a photo and a date on the site record so it can be tracked to closure separate from the contractor's report.

Elevator inspector's periodic test and report on file

Date the elevator inspector witnessed the periodic test and the inspector's report kept on file, with the renewed certificate from the AHJ replacing the posted copy.
