Maintenance · Inspection · Preparation

This page explains our maintenance approach: diagnosis, servicing, technical checks and repairs. Our technician works in workshops, business premises and on work sites to help reduce machinery downtime.

On-site maintenance and repairs

PRONK provides preventive and corrective maintenance for a wide range of machinery and equipment, including:

  • road construction and maintenance machinery;
  • road resurfacing equipment;
  • binder and emulsion sprayers;
  • chip spreaders and spreading equipment;
  • earthmoving and construction machinery;
  • agricultural and grounds maintenance equipment;
  • industrial machinery and technical installations;
  • hydraulic, pneumatic, mechanical and electrical systems.

Each intervention begins with an assessment of the fault or technical requirement. Depending on the situation, the work may include diagnostics, dismantling, repairs, component replacement, adjustments, functional testing and recommissioning.

Independent Machine Condition and Safety Inspection

PRONK provides independent inspections of machine condition and safety, with technical follow-up adapted to each machine.

Our services may include:

  • visual and functional examination of the machine;
  • inspection of mechanical, hydraulic and electrical systems;
  • checking control systems and safety devices;
  • identification of defects, damage and worn components;
  • preparation of machinery for functional checks and tests;
  • technical repairs and corrective work;
  • preparation of a clear list of identified issues and recommended work;
  • implementation of a preventive maintenance programme.

These independent technical inspections assess the machine’s condition and operation and help improve safety, reliability and availability. Any required statutory inspections remain separate.

Road maintenance machinery specialist

PRONK has extensive experience in the maintenance of machinery used for road construction, road maintenance and surface dressing, including:

  • binder and bitumen emulsion sprayers;
  • chip spreaders;
  • tack coat application equipment;
  • surface dressing and wearing-course equipment;
  • binder and aggregate dosing systems;
  • hydraulic circuits, pumps, spray bars and control systems.

We provide seasonal maintenance, fault diagnosis, repairs, complete overhauls, machine adjustments and dosing checks. We can also train operators and technical teams in the correct operation, maintenance and troubleshooting of their equipment.

Industrial maintenance, welding and fabrication

Our technical services are not limited to road construction machinery. PRONK also works on industrial equipment and technical installations, providing fault diagnosis, mechanical repairs and maintenance services.

Depending on the project, we can carry out welding, fabrication, sheet-metal work, machine modifications and mechanical assembly. These services can be used to repair a component, reinforce a structure, adapt existing equipment or modernise a machine.

Independent support in three languages

We look for a technically appropriate, durable solution that meets the business’s actual needs, without imposing a brand. You can speak with us in French, English or Dutch. Spare-part identification and supply, together with operator and technician training, complement this support.

Service area

PRONK is based in Segré-en-Anjou Bleu, in the Maine-et-Loire department of France. We provide on-site services in Maine-et-Loire, Pays de la Loire and throughout France and consider assignments elsewhere in Europe and internationally according to the equipment, urgency and expected duration of the work.

Preparing your request

For a breakdown, preventive servicing or an independent machine condition and safety inspection, provide the model, serial number, location, requested work, fault codes and any photographs or technical documents available.
