Reviewed by Lukasz Zelezny for the Montanari Giulio range. Inside many UK lifts — Otis, KONE, Schindler, TK Elevator badges included — sit Montanari Giulio components. This page helps engineers and technical building managers identify which Montanari Giulio part is fitted, understand its typical failure behaviour, and order the correct spare first time. It is not an end-user guide, and all mechanical work is engineer-only.
Quick Diagnosis
Answer up to three questions. We'll point you at the most likely Montanari Giulio fault on this page — full detail stays visible below either way.
Common Montanari Giulio Faults
The montanari giulio lift problems reported most often to UK service desks — expanded in the order owners typically encounter them. Several are resolved by routine Montanari Giulio maintenance rather than a call-out, and the rest are far quicker to fix when you can describe the symptom precisely to whoever handles your Montanari Giulio repair.
Identifying a Montanari Giulio drive or machine in the machine room
Engineer onlyConfirming the Montanari Giulio drive, motor, or gearless machine fitted to your lift.
Most people arriving at Montanari Giulio troubleshooting pages describe the problem in roughly these words.
The drive or traction machine of a UK commercial lift is the single most expensive component in the fitting, and identifying it accurately protects the value of every spare and every service decision.
The plate on a Montanari Giulio machine gives the model designation, serial number and often the maximum load — photograph it in full.
On modern MRL (machine-room-less) lifts the Montanari Giulio machine is above the shaft rather than in a separate machine room. Either way, only a competent lift engineer should be inside the space.
Building operators should ask their contractor for a photo of the Montanari Giulio plate at the next visit and file it with the lift's log. Keep the Montanari Giulio maintenance paperwork with the lift.
Whoever attends the Montanari Giulio repair will want to see when the last service was done.
Montanari Giulio brake not holding or not releasing
Engineer onlyThe Montanari Giulio traction brake is showing symptoms of holding failure or drag.
Before you phone anyone about a Montanari Giulio repair, work through the description below.
The brake on a Montanari Giulio traction machine is a safety-critical component: it must hold the loaded car at the floor with the motor de-energised. Must release cleanly when the drive commands a start.
When a Montanari Giulio brake fails to hold, the car rolls slightly at every stop and produces the classic levelling error above or below the floor; when it fails to release.
The drive trips on over-current within seconds of the call. Both are engineer-only diagnoses on any Montanari Giulio machine and both are more and more urgent.
A brake fault is one of the fastest routes from "in service" to "unsafe". Building operators noting the symptom pattern accurately helps the Montanari Giulio engineer diagnose the fault at the first visit.
Faults in this family are largely prevented by keeping to the Montanari Giulio servicing schedule, so check the date of your last Montanari Giulio maintenance visit while the paperwork is out.
Montanari Giulio encoder feedback loss
Engineer onlyThe Montanari Giulio drive has tripped with an encoder or feedback fault.
This symptom accounts for a steady share of the Montanari Giulio repair enquiries we see each month. The encoder on a Montanari Giulio traction machine reports position and velocity back to the drive.
It is the reference the drive uses to command the motor.
An encoder fault on a Montanari Giulio drive shows up either as a specific coded trip on the drive display or as more and more erratic levelling at floors.
Diagnosis is engineer-only; the Montanari Giulio drive log records the trip and the underlying cause is usually an encoder cable fault, a connector working loose with vibration, or the encoder disc itself contaminated.
Building operators seeing the same Montanari Giulio trip repeatedly should pass the trip code to the contractor rather than accepting a mains reset as the resolution. Add it to the log.
Planned Montanari Giulio maintenance is always cheaper than reactive Montanari Giulio repair. The log is what turns a vague complaint into a booked servicing job.
Montanari Giulio motor overheating
Engineer onlyThe Montanari Giulio traction motor thermal is tripping the lift out of service.
This is one of the most common reasons UK owners look up Montanari Giulio troubleshooting in the first place.
A Montanari Giulio traction motor has a thermal cut-out that fault-locks the lift when the motor winding temperature exceeds its rated limit. Repeated thermal trips on a Montanari Giulio motor are always symptomatic.
They can be caused by airflow to the machine or MRL space being blocked, by ambient temperatures in the machine room rising above the design limit in summer, by mechanical drag increasing the load on the motor, or by a fault in the Montanari Giulio drive that is pulling more current than the motor can shed as heat.
Building operators should check the Montanari Giulio machine-room airflow is clear and log any recent changes. The underlying cause is a Montanari Giulio engineer diagnosis.
Where the checks do not settle it, describe the symptom in your own words when you ask for Montanari Giulio repair. A plain description helps far more than a guessed diagnosis.
Montanari Giulio drive tripping on over-current or over-voltage
Engineer onlyThe Montanari Giulio VVVF drive is showing repeated over-current or over-voltage trips.
Of every Montanari Giulio troubleshooting question sent to us. This symptom is among the most frequent.
The Montanari Giulio VVVF (variable-voltage, variable-frequency) drive protects itself and the traction machine by tripping on abnormal current or voltage.
Repeated Montanari Giulio trips on the same indicator are diagnostic: over-current usually points to a mechanical load fault (brake dragging, guide-shoe seizure), over-voltage to a regenerative-braking issue where the Montanari Giulio drive can't dump the energy of a descending loaded car quickly enough.
Neither is a building-operator diagnosis. The Montanari Giulio drive event log is the primary source of truth.
The value of building staff noting the pattern is that it tells the engineer whether to bring parts for the mechanical or the electrical suspect.
A short entry in the Montanari Giulio maintenance log now avoids any later doubt about whether the fault was reported before the next Montanari Giulio servicing visit.
Montanari Giulio traction machine bearing noise or vibration
Engineer onlyThe Montanari Giulio machine is developing a rumble or vibration that carries into the car ride.
Read this through before booking any Montanari Giulio repair. The answer is often simpler than it looks.
Bearing wear on a Montanari Giulio traction machine is characteristically an ageing symptom: the ride quality of the Montanari Giulio lift gradually degrades, a low-frequency rumble appears on travel that wasn't there at start-up testing, and vibration more and more transmits into the car.
Left alone, bearing wear ends with a machine seizure and a long out-of-service period.
The value of catching it early is huge — a planned Montanari Giulio bearing service is a fraction of the cost and time of a failed-machine recovery.
Building operators should log ride-quality changes on the Montanari Giulio lift on the maintenance log rather than waiting for a fault to be reported by users.
Whatever the outcome, note the date and the symptom in your Montanari Giulio maintenance record. A clear history makes the next Montanari Giulio servicing visit quicker.
Montanari Giulio repair
Before booking a Montanari Giulio repair, separate the symptom from the cause. A lift component that halts mid-travel, one that will not start, and one that starts then stops are three different jobs even when they look identical from the landing. Note which of the three you have, plus the last thing that changed — a power cut, a new floor covering, a delivery knock — and hand that to whoever attends.
Anything behind a cover or panel, in the pit or shaft, or involving doors, gates and interlocks is engineer-only work. Your part of a Montanari Giulio repair is to check and report: mains power on, isolator on, emergency stop out, nothing in the door threshold, and a written note of the fault code.
What Noise Is Your Montanari Giulio Lift Making?
Lifts talk. Not eloquently — but a grind, a beep or an ominous silence each means something. Press play, compare, and pick the closest match.
Example sounds are synthesized approximations to help you compare — not recordings of Montanari Giulio equipment.
Grinding — likely causes on a Montanari Giulio lift
⚠️ Engineer only- Motor bearing at end of life on a drive unit
- Door-operator gearbox worn out
- Sheave or pulley bearing failure
Grinding from a Montanari Giulio lift component in service is a bearing or gear reaching end of life — motor, sheave, door-operator gearbox, or drive input.
The correct response from a lift engineer is to spot which unit is the source (bearings and gears each have distinct signatures on a stethoscope), order the correct Montanari Giulio service part, and plan the shutdown.
This is not a page for end users to work from: any mechanical work on Montanari Giulio drive. Motor or door components needs manufacturer training and the correct lifting equipment.
Building managers should log the fault and route the Montanari Giulio part number to their contractor.
What Light Is Your Montanari Giulio Lift Showing?
Lifts also talk in light. Pick what you can see.
Steady red — on a Montanari Giulio lift
⚠️ Engineer only- Drive-unit fault LED latched on the controller
- Door-operator fault indicator raised at end-of-stroke
- External enable input from the whole-lift controller withdrawn as a fault
Solid red on a Montanari Giulio lift is the controller saying it will not move until an open safety input is closed or a latched fault is cleared.
The common causes here are the boring ones, which is good news. The right first step is simple: confirm the doors close fully. That no stop switch is left operated.
That nothing visible is holding a safety contact open. If it clears, resume normal use. If it persists, report it: keep the lift powered, avoid repeat attempts.
Give your service company the precise light state along with what you already checked.
Is It Safe to Keep Using It?
Three questions. Ten seconds. Answer honestly.
When to Call an Engineer
Safety-critical systems are the engineer's remit, not yours. Contact the company servicing your Montanari Giulio lift, or use the form below, if you see:
- Repeat faults minutes after a reset.
- Burning smell, smoke, or visible cable or control damage.
- Water in the pit, machine room or car.
- The car outside its normal range or not level at the landing.
- Doors, gates or interlocks that behave differently each trip.
Montanari Giulio servicing
Regular Montanari Giulio servicing is the cheapest fault prevention available. A visit typically covers the drive and safety circuits, battery condition, charge points, limit and door detection, and a test of the alarm — the same items that generate most emergency calls when they drift out of tolerance.
Keep every service sheet. A dated history of Montanari Giulio servicing tells the next engineer which parts have already been changed, supports any warranty claim, and is the first thing a buyer's surveyor asks for when the property changes hands.

Montanari Giulio maintenance
Treat Montanari Giulio maintenance as a short weekly routine: confirm the lift component responds normally from every landing, confirm the alarm is audible where somebody would hear it, and confirm the charge indicator behaves as it always has. Anything outside that pattern goes to your provider rather than into a toolbox.
Nothing in owner-level Montanari Giulio maintenance involves removing covers, entering the pit or shaft, or adjusting doors, gates or interlocks. If a check cannot be done from the landing with the equipment behaving normally, it belongs to a qualified engineer.
Frequently Asked Questions
Is my own Montanari Giulio component covered by this page?
Montanari Giulio is a component (machines/motors) manufacturer active in Italy (global). The ranges most often met in the UK are Gearless machines, gearboxes, motors, overspeed governors.
The fault-finding below is written around the behaviour those Montanari Giulio ranges share rather than around one model number.
So start here and then confirm your exact model from the rating plate before you quote anything to an engineer.
One thing worth knowing: the reference note for Montanari Giulio reads "Fitted across many lift brands". This can change whose manual actually applies to your machine.
Where does a Montanari Giulio component show its fault code?
On Montanari Giulio equipment the sign is described as: Mechanical symptoms; drive-side fault codes. Codes are not standardised between makers, or even between board generations within Montanari Giulio, so photograph exactly what you see.
The characters, the lamp colour, the flash pattern — and report that with the model from the plate. Read the sign; do not open the Montanari Giulio controller or any panel to chase it.
Which Montanari Giulio problem comes up most often?
The fault this page opens with is "Identifying a Montanari Giulio drive or machine in the machine room". Confirming the Montanari Giulio drive, motor, or gearless machine fitted to your lift.
The next most reported Montanari Giulio symptom is "Montanari Giulio brake not holding or not releasing".
Work through the safe checks listed against each one, note what you observe, and pass that to a competent lift engineer.
All on this page stops at check-and-report: nothing here asks the maintenance contractor to force a door, move a stalled car, remove a panel or enter a pit or shaft.
Is there an official Montanari Giulio source for fault information?
The authoritative reference for this brand is the Montanari Giulio product manuals. Montanari Giulio publishes to its own channels and to registered trade accounts rather than openly.
So if you have no account, ask your maintenance contractor to supply the Montanari Giulio document that covers your fitting.
Our own coverage of Montanari Giulio is currently rated "System-level", so treat this page as an orientation and the manufacturer's document as the authority.
How do I identify which Montanari Giulio component is fitted?
The Montanari Giulio manufacturer's plate is on the component itself. It is not the badge on the car — a lift wearing one brand's name usually carries Montanari Giulio parts inside.
Ask your engineer to photograph the Montanari Giulio plate during a planned visit. The car top, machine room and MRL space are engineer-only areas.
