DM Works diagnoses, repairs, and modernizes elevators and escalators already in service — from a single sticking door to a full control-system rehab — with minimal downtime for the building.
Most service calls trace back to a short list of wear points. We diagnose against the fault first, then decide between a repair and a fuller rehab.
Cab stops short of or past the landing, usually from worn leveling sensors or a drifting drive controller.
Cab or landing doors drag, stick, or rattle as door rollers and tracks wear unevenly over years of cycles.
Relay-based or discontinued controllers with no parts supply, creating growing downtime risk.
Audible clicking or vibration from a stretched step chain or worn chain rollers under load.
Handrail speed no longer matches step speed, or the rail slips under grip due to drive-belt wear.
Cracked or missing comb teeth and worn skirt panels create a real entrapment risk at the landings.
Drive motor trips on thermal overload from a failing bearing, blocked ventilation, or age-related winding wear.
Rumbling or knocking in the cab, typically from worn guide shoes or roller guides losing contact with the rail.
Every rehab job runs against the same list — nothing gets signed off until the item above it is done and tested.
A technician logs every fault against the unit's service history and rates each one by safety risk and downtime cost.
We draw up a repair-vs-rehab scope, source OEM or equivalent parts, and schedule the work around the building's traffic.
Worn parts are swapped in place — rollers, chains, sensors, controllers — with the unit taken offline in the shortest viable window.
Leveling, speed, alignment, and every safety device are retested against original spec, not just against the old fault.
An independent inspection closes out the work order, and the unit's maintenance plan is updated with everything that changed.
