Escalator Maintenance Checklist & Inspection Guide

By Mark Strong on April 6, 2026

Escalator failures injure passengers and shut down revenue-critical transit points — and 70% of those failures show detectable precursor conditions at the prior inspection. This checklist gives facility engineers and escalator maintenance teams a structured component-by-component assessment protocol covering 42 inspection items across six zones. Each item is a single observable or measurable condition with a priority rating based on failure consequence. Complete it at every scheduled PM visit and as a walkdown observation between visits. For digital completion with automatic work order routing, deploy via OxMaint's zone-based inspection module. Book a demo to see how OxMaint converts this checklist into live digital work orders.

Checklist Scope and Usage

This checklist covers six zones: step chain and sprockets, handrail and drive system, comb plates and step treads, safety devices, drive machine and brakes, and controller and electrical. Critical items have a short window to passenger injury or code violation. Monitor items require a work order and defined re-inspection. Routine items are documented and trended. All FLAG findings require photo documentation before the work order is raised.

Step Chain Handrail Comb Plates Safety Devices Drive and Brakes Controller

Zone 1 — Step Chain and Sprockets

The step chain is the primary drive mechanism. Chain elongation beyond 2% requires immediate replacement per ASME A17.1. Sprocket tooth wear accelerates chain elongation — both must be measured together.

Chain Condition — Monthly Measurement

Step chain elongation below 2% of original pitch — measured with calibrated chain gauge at minimum 3 positions per chain strandCritical No cracked, bent, or seized chain links visible on both inner and outer chain strands through full travel inspectionCritical Chain roller bushings rotating freely — no flat spots, seizure marks, or excessive lateral play on accessible rollersMonitor Chain tension within manufacturer specification — chain sag at midpoint between drive and return sprockets within limitMonitor Chain elongation measurement logged with date, positions measured, and values recorded for campaign trendingRoutine

Sprocket Condition

Drive and return sprocket teeth showing no hooked profile, root cracking, or asymmetric wear patternCritical Sprocket keyway and shaft fit secure — no axial movement or wobble observed during slow-speed operationMonitor Chain-to-sprocket engagement smooth with no climbing, skipping, or abnormal noise at drive and return stationsRoutine

Zone 2 — Handrail and Drive System

Handrail speed must match step speed within 2% per ASME A17.1. Speed mismatch causes passenger imbalance — the second most common escalator injury mechanism after comb plate entrapment.

Handrail Speed and Condition — Weekly Check

Handrail speed within 2% of step speed — measured with tachometer or calibrated timing method at upper and lower landingCritical No cuts, tears, or splice separation visible on handrail surface through full-length visual inspectionCritical Handrail entry points at upper and lower landings free from gaps exceeding 8mm that could trap fingers or clothingCritical Handrail drive roller pressure uniform — no slipping, hesitation, or speed variation during loaded operationMonitor Handrail guide channel clean and aligned — no debris accumulation or guide misalignment causing handrail tracking driftRoutine

Zone 3 — Comb Plates and Step Treads

Comb plate entrapment is the leading cause of escalator passenger injuries. Missing teeth, worn step cleats, and excessive comb-to-step clearance create entrapment hazards that must be checked daily.

Comb Plate Condition — Daily Visual / Monthly Measurement

All comb plate teeth present and intact at upper and lower landings — no missing, broken, or bent teethCritical Comb-to-step cleat clearance within specification — no gap exceeding 6mm at any point across the full comb plate widthCritical Comb plate seating secure — no vertical movement or rocking when firm pressure applied to the plate surfaceMonitor Comb plate impact switch functional — confirmed by manual depression test during maintenance mode operationMonitor

Step Tread Condition

Step tread cleats complete with no missing, cracked, or worn-smooth cleats on any step in the visible runCritical Step-to-step gap at upper and lower transitions within specification — no gap exceeding 6mm between adjacent step nosingsMonitor Step roller tracking smooth — no clicking, bumping, or hesitation at transition curves on slow-speed inspection runRoutine

Zone 4 — Safety Devices

Every safety device must be tested on schedule. A failed safety device that goes undetected creates maximum liability exposure — regardless of the condition of every other component.

Safety Device Testing — Monthly

All emergency stop buttons functional at upper landing, lower landing, and any intermediate access points — tested by activationCritical Skirt deflection switches functional on both sides — confirmed by inserting test object to simulate clothing entrapmentCritical Broken step chain device functional — confirmed by test activation per manufacturer procedure (not live chain break)Critical Step level fault sensor operational — detects step sagging or misalignment that could cause tripping hazardCritical Handrail entry safety switch functional at upper and lower entry points — triggers stop on obstruction detectionMonitor Missing step detector functional — confirmed by removing one step during maintenance mode and verifying shutdown triggerMonitor All safety device test results logged with date, tester ID, pass/fail status, and next test due date per unitRoutine

Zone 5 — Drive Machine and Brakes

Brake failure causes either runaway (acceleration beyond safe speed) or sudden uncontrolled stop — both produce serious passenger injuries. Stopping distance must be measured, not estimated.

Brake System — Monthly Test

Operational brake stopping distance within manufacturer specification — measured under loaded conditions at rated speedCritical Auxiliary (emergency) brake engages correctly on power loss simulation — escalator decelerates smoothly without jerk or reboundCritical Brake pad thickness above minimum — measured with caliper or visual indicator mark per manufacturer specificationMonitor No oil contamination on brake disc or pad surfaces — oil film prevents proper friction engagement and extends stopping distanceMonitor

Drive Motor and Gearbox

Motor current draw within rated specification — measured under loaded operation and compared to baseline trendMonitor Gearbox oil level within sight glass normal range — no discolouration, metallic particles, or emulsification visibleMonitor No abnormal noise or vibration from gearbox during operation — compare to baseline sound recording if availableRoutine Motor bearing temperature below 70°C — any bearing exceeding 85°C flagged for immediate investigationRoutine

Zone 6 — Controller and Electrical

Controller faults cause intermittent shutdowns that frustrate building operators and reduce escalator availability. Relay degradation and contactor wear are progressive — test proactively.

Controller Inspection — Quarterly

Controller enclosure clean and free from dust, debris, and moisture — environmental contamination accelerates relay and contactor failureMonitor Relay contacts showing no pitting, burning, or discolouration — contacts with visible degradation replaced proactivelyMonitor All wiring connections tight with no signs of thermal damage, insulation cracking, or corrosion at terminal blocksMonitor Fault log reviewed — any recurring fault codes documented and investigated rather than cleared and ignoredRoutine

Frequently Asked Questions

How often should escalators be inspected?

Daily visual checks for comb plates and step treads. Weekly handrail speed verification. Monthly safety device testing and chain measurement. Annual full inspection per ASME A17.1 or EN 115. OxMaint auto-schedules all frequencies per unit. Book a demo.

What is the most common escalator safety hazard?

Comb plate entrapment — where shoes, clothing, or objects are caught between step cleats and comb teeth. Preventable with daily visual checks and monthly gap measurement, both auto-tracked in OxMaint.

When should a step chain be replaced?

ASME A17.1 requires replacement when elongation exceeds 2% of original pitch. OxMaint tracks monthly measurements per unit and alerts when any chain approaches threshold. Start free.

Can OxMaint manage escalators and elevators together?

Yes. OxMaint manages your entire vertical transportation fleet — escalators, elevators, and moving walkways — from a single dashboard with asset-specific PM templates and portfolio-wide reporting.
