Crane Commissioning Inspections: A Handover Checklist for Owners

Record whether the project involves a new installation, relocation, reassembly or a changed configuration. Identify the crane, supporting structure, runway or foundation where relevant, and the boundaries between suppliers. Separate responsibilities prevent an interface from being overlooked.

Commissioning requirements depend on equipment type, manufacturer instructions, the installation and applicable legal and technical requirements. A checklist for an overhead crane cannot simply be copied to a mobile crane or vehicle loading crane without checking what applies.

The crane commissioning inspection service can help establish which checks and documents are relevant to the installed crane before the handover date.

Obtain the documents before the inspection so inconsistencies can be resolved while suppliers are still available. Equipment labels, drawings, serial numbers and configuration records should describe the same asset. A certificate for a component is not necessarily evidence for the completed installation.

For example, a hoist test record may identify the hoist correctly but say nothing about the runway or supporting connections. The owner needs to understand which project records cover those interfaces and which items remain outside the inspection scope.

• Asset identity, rated capacity information and configuration-specific operating documents.
• Manufacturer manuals, installation instructions and relevant approved drawings.
• Installation, assembly and supporting-structure evidence within the project scope.
• Inspection and test plans, applicable reports and unresolved non-conformances.
• Maintenance requirements, operator information and emergency arrangements.

Agree safe access and the commissioning sequence with the site team. Controlled functional checks may involve movements, travel limits, brakes, emergency stops and protective systems, as appropriate to the equipment. Testing needs competent personnel and a coordinated exclusion area.

Load testing, where required, needs its own agreed method, resources and acceptance criteria. Do not assume a universal test load or improvise a site lift. The commissioning plan should identify who authorises each stage and what happens if a defect prevents progress.

A punch list should distinguish a missing document from a defect that prevents operation. Each item needs an owner, a required action and evidence of close-out. Avoid vague entries such as 'supplier to check' without a defined outcome.

Conditional acceptance needs particularly careful control. Restrictions must be clear to the people using the crane, and safety-critical outstanding matters must not be treated as routine administration. Ask the competent assessor to explain how unresolved findings affect handover.

After commissioning, enter the asset into the inspection and maintenance system using its confirmed identity and configuration. Keep baseline reports accessible for later comparison. Provide operators and maintainers with the relevant manuals, limitations and defect reporting arrangements.

Commissioning is not a guarantee that later use will remain compliant regardless of conditions. Changes in duty, location or configuration may trigger further review. The handover should identify how future changes are assessed, rather than ending with a folder of certificates nobody owns.
