Proof load testing for lifting and engineered equipment
What is proof load testing?
Proof load testing is used to verify that lifting equipment, fabricated structures and engineered assemblies can safely withstand a specified load under controlled conditions before being placed into service.
Controlled verification under load
During a proof load test, a controlled load is applied using a defined testing arrangement. This allows engineers to verify structural performance, connection integrity and load behaviour under the required proof load condition before the item enters service.
Engineering review
Drawings, dimensions, connection details and required proof loads are reviewed to determine the safest testing method.
Controlled load application
Load is applied using calibrated hydraulic systems, test beds or bespoke engineered arrangements.
Inspection & certification
Following successful completion, inspection findings and certification documentation can be provided where required.
Proof load testing for lifting equipment, structures and engineered assemblies
Durham Lifting supports proof load testing for lifting equipment, fabricated structures, rigging systems and bespoke engineered items using controlled load application methods at Britannia Test House and, where suitable, on site.
Many proof load testing projects involve custom load application methods, engineered fixtures or specialist support structures designed specifically for the item being tested.

Frequently asked questions
Common questions about proof load testing, testing capability, certification, engineered arrangements and on-site testing support.
What is proof load testing?
Proof load testing is used to verify that lifting equipment, structures or engineered assemblies can safely withstand a specified load under controlled conditions before being placed into service.
What types of equipment can be proof load tested?
Durham Lifting supports proof load testing for lifting beams, spreader beams, rigging systems, fabricated structures, pad eyes, lifting lugs, offshore equipment, wire rope assemblies and bespoke engineered fabrications.
Can Durham Lifting carry out proof load testing on site?
Yes. Selected proof load testing projects can be completed on site where suitable access, reaction points and controlled load application methods are available.
Do you provide certification following testing?
Yes. Certification and supporting inspection documentation can be provided following successful completion of the proof load test where required.
Can you create bespoke testing arrangements?
Yes. Many proof load testing projects require bespoke engineered arrangements, specialist support structures, hydraulic systems or controlled jacking methods designed specifically for the item being tested.
What information do you need for a testing enquiry?
Useful information includes drawings, dimensions, connection details, photographs, required proof load, certification requirements and whether testing needs to be completed at Britannia Test House or on site.
Can testing be witnessed by a third party?
Yes. Proof load testing can be supported by client representatives, surveyors or third-party witness attendance where required by the project or specification.
Where is proof load testing carried out?
Many projects are completed at Britannia Test House in Middlesbrough using our horizontal and vertical testing capability, although selected projects can also be supported on site where appropriate.
