Common inspections include:

  • weld inspection and "non-destructive testing" to identify any cracked or reduced thickness welds.

  • Inspection of stainless steel cladding on any mild steel frame to identify areas of ingress of water or corrosion of the mild steel.

  • condition checks of cantilever beams and building reaction points (often badly corroded at the wet end of the machine)

  • inspection of screw-jacks and cylinders to check for reduced load carrying capacity
