2.10.2 Interim Inspection

In addition to the thorough examination and pre-use inspection some cranes will require an interim inspection(s). The number, frequency and extent of interim inspection(s) is based on risk assessment taking into account the possibility of deterioration of components and assemblies based on the conditions of the specific use, to ensure that they are identified before they become a danger to people.

The risk assessment must take into account the manufacturers’ literature, crane duty and the actual conditions of use, for example environmental conditions and utilization that can cause deterioration. The inspection can be restricted to those critical components identified in the risk assessment and therefore are not as detailed as the thorough examination. Typically, the interim inspection will be a detailed inspection of one or more of the items listed in 2.10.1 Pre-use Inspection but may also include components covered by the thorough examination (refer to the Manufacturers literature as guidance for defined scopes of thorough examination including acceptance and rejection criteria).

Interim inspections are often done at the same time as planned maintenance.
