Lifting Equipment Testing
All lifting equipment is required to be tested post installation, and this is done through replicating the lift with a calibrated load.
We will ensure that any and all equipment is tested safely and efficiently, and can be conducted in the following ways:
MPI (Magnetic Particle Inspection)
Following LEEA guidelines, calibrated weights with a prescribed overload replicate the lift. We conduct this test with our own weights and water bags, where appropriate, on Ship’s cranes and Davits for example.
This is more of an efficient way to test onsite, and consists of using a ram or pulling against a fixed point and measuring the load with a calibrated load cell in order to get the overload.
We have in-house facilities that allow for up to 200t to provide a controlled overload test.
For newly designed equipment or batch testing, we recommend getting a Destruct Test. It determines the SWL of equipment by breaking the apparatus by applying increasing loads on our test beds. We are able to carry out a load test and then submit a certificate for the results. We require a complete set of design calculations for any items with a defined SWL to verify its construction before we can issue a certificate for it.
This may be required by surveyors in order to check the integrity of the welds. The test is performed on a clean weld, 24 hours after the weld has been initially made; it cannot be painted or covered as it will interfere with the testing process.
