Crane Hook is considered a “Safety Related” component, having high-level tests and inspections before and during its life span.
1.1 TENSILE
A sample is subjected to a controlled tension until failure.
1.2 IMPACT (Charpy)
The Charpy impact test is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture.
1.3 HARDNESS
With an indenter tool, a force is applied on the material surface during a specific time.
NON DESTRUCTIVE TESTS
Internationally called NDT, where the integrity of the piece itself is tested.
Mandatory NDT tests performed are:
2.2 MPI (Magnetic Particle Inspection)
This inspection technique aims to detect discontinuities in the surface of the forging made by ferromagnetic steel grade.
2.3 FAT (Functional Acceptance Test)
It consists of some testing operations which aim to ensure the correct functional operation of the different elements.
2.4 PLT (Proof Load Test):
Mandatory in some countries (as the US, GB Common Wealth Countries…) and applications (Offshore, Subsea, Mooring, Nuclear…), this is the key test where a physi
Mandatory DT & NDT test results are an integral part of EN10204-3.1 Certificate issued by the hook manufacturer, which can be validated by a recognized third party (LRS, BV, A
