Machine repair

Industrial machine repair in Switzerland

VLD Service GmbH repairs industrial machines and production plants in Switzerland. Our technicians handle fault finding and repair on mechanics, electrics, drives, sensors and PLC controls. For production breakdowns we run a 24/7 on-call service (Pikettdienst) from our operational base in Wangen bei Olten, canton of Solothurn.

Which industrial machines do we repair?

Machines and lines that run in production plants, with a focus on the food industry. The brand does not matter: we arrive with measuring instruments, a programming laptop and tools for mechanics, electrics and controls.

  • Conveyor systems

    Belt conveyors, roller tracks, chain conveyors, screw conveyors: belt replacement, drives, bearings, sensors and PLC integration.

  • Production lines

    Interlinked lines with several stations, where the fault sits in a handover, an interlock or a step sequence.

  • Washing and cleaning systems

    From crate washers to tunnel washers: nozzles, pumps, heating, seals, valves and controls.

  • Packaging and sorting systems

    Sorting systems, packaging lines, infeeds: mechanics, drives, safety circuits and PLC.

  • Filling and process plants

    Filling, pasteurisation, CIP piping, tank storage: stainless steel piping, valves, pumps, sensors.

  • Drives and gear motors

    Gear motors, frequency converters, soft starters: reading fault codes, checking parameters, measuring load, replacing the component.

  • Control cabinets

    Contactors, circuit breakers, converters, safety relays and wiring to EN 60204-1, even without up-to-date schematics.

  • PLC-controlled machines

    Siemens S7-300, S7-1200 and S7-1500 with TIA Portal, Beckhoff TwinCAT: reading the program, tracing interlocks, correcting parameters.

Which faults do we fix?

Assigning a fault to one trade is rarely clear-cut. A converter trips because the mechanics have become stiff; a sensor bounces because the terminal is damp after the wash cycle. That is why mechanics, electrics and controls come with the same team to the same machine.

Mechanical faults

Failed gear motors, torn conveyor belts, seized drives, worn bearings, broken shafts, leaking pipework, damaged stainless steel structures. Repaired on site, with TIG welding directly on the plant where needed.

Mechanics and assembly

Electrical faults

Short circuit, earth fault, cable break, failed safety circuit, a contactor or breaker that keeps tripping. Measured, isolated and fixed, including on older plants without current schematics.

Electrics and panel retrofit

PLC and automation faults

Program crash, a step sequence that stalls, an interlock that will not release, bus errors on Profinet or Profibus, an HMI showing stale values. We go online on the controller instead of copying the error message.

Automation and PLC

Sensors and actuators

Proximity switches, light barriers, encoders, valve terminals, cylinders: signals measured at the device, not assumed. Loose contacts, damp terminals and cable breaks are found at the machine, not at a desk.

Fault finding at the machine

Drives and frequency converters

Reading fault codes, comparing parameter sets, measuring load behaviour. Converters from ABB, Siemens, Danfoss and SEW, including the question of whether the drive itself is failing or only reporting what the mechanics cause.

Converters and drives

Conveyor technology

Belt replacement and tracking, drive exchange, bearing checks, sensors and PLC integration on conveyor systems from any manufacturer, from Intralox and Habasit to custom builds.

Conveyor system repair

Food industry machines

Plants that are washed down every day: moisture, detergents and temperature swings are a frequent cause of faults in this industry. We know these conditions from over 60 interventions since 2025.

For production companies

How we proceed when a machine fails

From the call to the report in five steps. During an ongoing stoppage everything runs through the on-call number, around the clock.

  1. Call and first assessment

    Which plant, which message, what changed recently. This narrows the search to one area and decides which material comes along.

  2. On site at the machine

    Measuring instruments, programming laptop and tools for all three trades travel in the same vehicle. No second appointment because the electrician is missing.

  3. Cause, not symptom

    We keep searching until it is clear why the fault occurs. A replaced part without a found cause costs you the next stoppage.

  4. Repair, in two stages if necessary

    If the line is down, production comes first: a safe interim solution so you can run, then the permanent fix in a planned window.

  5. Test and report

    Trial run under production conditions, then a report with photos, measured values and replaced parts. Plus the measure that stops the fault from coming back.

Service area: Switzerland

The operational base is in Wangen bei Olten, on the Swiss Plateau between Bern, Basel and Zurich. In German-speaking Switzerland we are usually on site within 4 hours. Interventions in western Switzerland and Ticino on request; the team works in German, French and Italian.

  • Solothurn
  • Aargau
  • Bern
  • Basel
  • Zurich
  • Lucerne
  • St. Gallen
  • Thurgau

Since 2025 at 25 production sites in Switzerland.

Manufacturer-independent service

We repair machines of any brand, including older controllers the manufacturer no longer supports. No spare-parts contracts or service agreements with individual brands tie us. Systems we work with on site:

  • Siemens S7-300, S7-1200, S7-1500, TIA Portal
  • Beckhoff TwinCAT
  • WinCC, Ignition (HMI/SCADA)
  • ABB, Siemens, Danfoss, SEW (frequency converters)
  • Intralox, Habasit, FlexLink, Interroll (conveyors)
  • Profinet, Profibus, OPC UA

24/7 on-call service for production stoppages

The on-call number is staffed 365 days a year, around the clock. You speak directly to a technician, not a call centre. Billing by time and material: hours, parts and travel.

Frequently asked questions

Who repairs industrial machines in Switzerland?
VLD Service GmbH from Wangen bei Olten (SO) repairs industrial machines and production plants across Switzerland: manufacturer-independent, with mechanics, electrics and PLC in the same intervention. The focus is the food industry. Since 2025, more than 60 interventions at 25 production sites are documented.
How fast are you on site during a production stoppage?
In German-speaking Switzerland usually within 4 hours of the call, around the clock. The exact time depends on your location and the current workload. You get a realistic estimate immediately on the phone.
Do you also repair machines you did not install?
Yes, that is the normal case. We work on plants of any brand, often precisely where the original supplier is abroad or the controller is considered too old for manufacturer service.
What does a machine repair cost?
We bill by time and material: hours, parts, travel. Fault finding cannot be planned as a flat rate, so we keep you informed during the intervention. For recurring support we prepare an offer with a fixed frame; the starting point is a free on-site analysis.
Can you narrow down the fault remotely?
Partly. Where remote access to the controller is set up, we read diagnostic data before anyone drives out. Sporadic faults on sensors, wiring and mechanics, however, are found at the machine, with the meter in hand.
What happens if a spare part is not immediately available?
We first secure production with an interim solution, then complete the repair in the agreed window as soon as the part arrives. We tell you on the phone what is realistic.
Do you also take over maintenance after the repair?
Yes. Many plants start with one intervention and then move to ongoing support: maintenance plan, documented condition reports and on-call coverage.
