Chain Inspection
At the Zeros materials testing laboratory, we perform professional non-destructive chain inspections specifically tailored to chain slings and lifting chains. Our testing procedures comply with DIN 685-5:2020-08 and ensure the highest safety standards and quality of your chain components.
We use state-of-the-art methods such as magnetic particle testing (MT) and dye penetrant testing (PT) to reliably detect surface cracks and material defects. The inspections are performed according to the requirements of DIN 685-5 and relevant standards to provide a comprehensive assessment of chain safety.
The triennial crack testing is an important part of the maintenance of lifting chains. We support you in timely execution of these inspections to maximize operational safety and the service life of your chains.
Our logistics service includes pickup of your chain slings directly at your site as well as timely return delivery after testing. This makes the inspection process especially convenient and efficient for you.
