Preventative Maintenance and Inspection

Regular maintenance and inspections keeps your testing systems running and ensures your safety and the safety of the machine. Additionally, you can significantly minimize wear and reduce downtime.

Cleaning and maintenance work should be performed by trained ZwickRoell service technicians. Settings and fill levels are adjusted and checked so that the calibration of your testing machine can follow.

prolonging your testing system's service life.

Preventive and regular maintenance and inspections carried out by ZwickRoell ensure that your materials testing machines and instruments function properly and reliably. Maintenance and inspection maintain the value of your machine and protects against unexpected repairs, prolonging your testing system's service life.

During the inspection, vulnerabilities can be uncovered and rectified in advance which could otherwise lead to erroneous test results and thus defective products. The system's general condition, its functions, and most importantly the safety-critical points should be checked regularly. Additionally, the wear and tear of wear parts should be assessed and documented.

The DIN EN ISO 7500-1 standard specifies the need for inspection prior to calibration.

The inspection not only maintains the reliability and full functionality of your testing machines, With a service agreement we track inspection intervals and industry-specific calibration intervals for you.

In addition to maintenance, we monitor individual maintenance intervals.

Your materials testing machine and instruments including all accessories must be serviced at regular intervals. On request, we perform these services for you as described in the user guide. In addition to maintenance, we monitor individual maintenance intervals. As part of maintenance services, we document the condition and any detected defects and recommend further measures.

Inspections are carried out in detail using checklists.

We determine the condition of the materials testing machine and instruments during the inspection. Necessary repairs and replacement of wear parts are completed immediately when possible. Our service technicians point out preventative measures and actions in order to plan and initiate the appropriate steps in a timely manner. Our service technicians have fully equipped service vehicles and always carry common spare parts and wear parts with them.

Changing the oil and filter

During operation, hydraulic oils are subject to wear and aging and must be changed at regular intervals. The need for this can be determined during a ZwickRoell on-site support visit.

Alternatively we recommend a preventive oil and filter change every two years to ensure that the hydraulic system is supplied with “fresh” oil. This will minimize wear to all hydraulic components and extend the service life of your testing system.

Oil analysis

Constantly increasing demands on the reliability, availability and cost-effectiveness of hydraulic systems call for ever-cleaner hydraulic fluids.

In addition to the size of the particles, the number is also decisive for the wear process of the system. Not every particle is damaging to the system, however, the smaller the number of critical particles the lesser the likelihood of damaging the components. Oil analyses can be performed at regular intervals by our ZwickRoell service technicians during on-site support. Both the quality and the suitability of the hydraulic oil will be verified.

If a determination is made that impurities, contamination or other influences are negatively affecting your hydraulic power pack, ZwickRoell offers proper measures to restore the necessary oil quality.

Hydraulic hose change

The use of aging hydraulic hoses can be dangerous. Hydraulic oil escaping at high pressure or whipping hoses can not only permanently damage your machine, they can also present heightened safety risks for your employees.

To eliminate these risks caused by wear, aging or damage, hydraulic hoses must be replaced according to requirements after a specified time in operation and storage. At ZwickRoell you get everything from a single source
