Crack Testing Services
Heavy duty wheels & rims used in Earthmover, Mining, Industrial & Agricultural applications, are often exposed to extreme loads and harsh operating conditions.
Tyres fitted to heavy duty 3 Piece and 5 Piece wheels and rims are inflated to very high operating pressures and as such are classified as pressure vessels.
Most industrial sites operating heavy equipment now require all wheels and rims to be periodically crack tested.

This specialised service is called Magnetic Particle Inspection (MPI) Crack Testing and must be carried out by a specially trained wheel technician.
