CSA B167 load testing for older bridge cranes

An older bridge crane often brings together original drawings, later modifications and decades of maintenance records. CSA B167, the Canadian standard for maintaining overhead travelling cranes, offers a useful framework, but Australian operators must still meet the Work Health and Safety laws and crane standards that apply at the workplace.

CSA B167 commonly sets a 48-month maximum between satisfactory proof-load tests for cranes rated above 10,000 kg, while lighter units may have a 60-month interval in the applicable edition. Treat either limit as a ceiling, not a default booking for an ageing machine: repairs, structural alterations, impact, suspected overloading, prolonged lay-up or deterioration can require testing sooner, and Australian rules or contracts may be stricter.

What CSA B167 covers

CSA B167 covers inspection, maintenance and repair of overhead travelling cranes; it does not replace design rules for crane structures or local law. It expects competent people to examine the crane, maintain traceability and use suitable test equipment. The precise duty depends on the edition cited in the crane’s documentation.

For an older bridge crane, follow the applicable B167 series and manufacturer instructions rather than mixing requirements from different editions. A controlled copy matters because inspection terminology, test provisions and record expectations can change. Confirm that the purchased document is the edition required by the client, safety system or regulator.

Why age changes the assessment

Age alone does not determine the next test date, but it weakens assumptions about condition and documentation. Legacy cranes may have unknown weld procedures, superseded component ratings, replaced controls or modified spans. A current-looking certificate may describe an earlier configuration and say little about the bridge above the workshop floor.

Older equipment also accumulates operational history: hard stops, chain blocks used for temporary lifts, overload events, water ingress and production-critical repairs. Australian crews may call a long-serving crane “the old girl,” but informal confidence cannot replace examining cracks, wheel flats, gearbox oil, brake wear, ropes and electrical protection.

Reading the load-test interval

The routine CSA B167 proof-load interval is generally expressed as no more than 48 months between satisfactory tests for cranes above 10,000 kg; some editions allow 60 months for lower-capacity cranes. The clock should follow the last valid test of the actual configuration, not a purchase date or annual inspection. A thorough examination, brake check or calculation does not replace a proof load test.

Any major repair, altered runway, new hoist, different trolley or changed safe working load can invalidate earlier assumptions and require engineering review. For related crane, lifting and materials requirements, browse the related standards catalogue, then confirm each document’s scope, edition and relationship to the governing procedure.

Australian requirements in practice

Australian duties sit under the model Work Health and Safety framework and the relevant state or territory regulator. A workplace controller, principal contractor or plant supplier may have separate duties, and workers must follow reasonable instructions. Appoint a competent person where legislation, the manufacturer or a risk assessment requires one.

AS 2550.4, AS/NZS ISO 9927 and relevant parts of AS 2550 may form the inspection regime; AS 1418 addresses crane design and construction. These documents do not become law merely because they are published, but they can be adopted through legislation, procurement contracts, safe work procedures or recognised risk controls. CSA B167 can be specified contractually.

Expect sharper rules around Pilbara mining, Newcastle port handling and Melbourne manufacturing. During a shut-down, a rigger, dogger and operator may call the work a lift and issue a lift ticket, yet that ticket may not satisfy the thorough-examination record required by legislation. Local language is useful; regulatory evidence closes the compliance gap.

Preparing for a proof load

Start with a pre-test examination and document review. The competent person should confirm the crane’s identity, rated capacity, reeving, span, trolley travel, runway condition, modifications, prior defects and maintenance history. Resolve uncertainty about structural adequacy or the test method before applying load.

The test plan should state the proof load, test positions, loading method, measuring equipment and acceptance criteria. Calibrated weights or a suitable load cell must be traceable, and the test must not overload the runway, trolley, hoist or other components. Exclusion zones, competent signalers and control of suspended loads are essential; nobody should stand beneath the load.

Where ALS2 project material forms part of the asset’s engineering file, use the ALS2 project record to trace design assumptions and alterations, then reconcile it with the machine and site conditions. It may support the engineering basis, but it cannot replace inspecting the physical crane or applying the current standard.

Essential records and checks

A test is only one part of the compliance file. The crane register should show what was checked, when, by whom and under which revision of the governing procedure. Keep records through the asset’s life, including transfer or disposal.

• Record the manufacturer, serial number, year of manufacture, rated capacity, configuration, location and every authorised modification.
• File the signed test report, applied load, crane configuration, calibration records, acceptance result, defects found and remedial close-out.
• Link the proof test to thorough examinations, maintenance, rope and brake inspections, incident reports and risk assessments.
• Identify the competent person or testing authority and retain their qualifications, authorisation and the applicable standard edition.

Digital copies are convenient, but controlled access matters. Store the report where supervisors, maintenance planners and auditors can retrieve it, and keep a printed copy for remote work or a site shut-down. Backups should preserve signatures and document revisions.

Keep the next inspection ready

Set an owner and calendar reminder against the applicable limit, then review the interval after every maintenance or modification. If no satisfactory test record exists, or the last test covered a different configuration, have a competent person determine the crane’s status before normal service resumes. Restrict use where structural doubts remain.

Buy the current controlled standard, brief the maintenance team and close the last defect before booking the next test.

Schedule the next proof load now, assign responsibility and turn the crane’s history into evidence the crew can trust.
