Check the lifting chains, lifting lugs, hammerlocks and other components of the chain assemblies to ensure that they are not damaged. The hammerlocks should be able to fold otherwise they have been overstressed and are in need of replacement
Check the Sidelifter, chassis and twistlocks for damage. For example, check that the container guides on the "non-lifting" side of the crane bases are present and not unduly bent or deformed.
Inspect the lifting module sliding areas on top of the main chassis for cleanliness.
