As mentioned at the subject certification. The certificate of the product expires after a certain period. Most of the times this is one year. Without a certificate you are not allowed to use the product. Fortunately the inspectors of Kwint can extend the certificates with their experience and knowledge. The products will be visual inspected and checked for errors. If no errors are found, the inspector can recertificate the product.
The visual inspection usually takes place at the customer location. Our mechanic comes along with a service bus and the required tools. The inspector has the tools to fix the most common errors, if it’s repairable of course.
It’s also possible that the certificate can’t be extended by means of a visual inspection. Then the item needs to be tested. Inspections and tests needs to be done, so you can work safely with your products.
In the table below you will find an inspection period matrix of all lifting equipment.

(because the periodic inspection can’t be separated from regular inspection, the inspection periods are contained in the above table.)
If there is evidence of conditions that the risk of damage to the capacity of the lift equipment is minimal, then the inspector can consider to omit a (NDT) test with overload.
- The lifting equipment shows no deformation, damage or excessive wear.
- The lifting equipment show no deterioration due to exceptional circumstances.
- The lifting equipment is at least annually inspected or tested by an expert for good condition.
The lifting equipment is during use, transport and / or storage not exposed to, special circumstances, like corrosion, salt, acids, chemicals, high temperature, pollution, UV radiation etcetera, which can affect the capacity of the lifting gear.
According to the criteria, every piece of lifting gear must be assessed separately. If the product does not meet the three criteria, still the inspection needs to be done according to appendix A or the lifting gear product needs to be rejected.
