An inspection of a construction crane that collapsed in Halifax during a storm in September revealed it wasn’t working properly four months earlier.

Citing government documents, Global News says the tower crane — owned by Lead Structural Framework Ltd. — was modified in May and June of 2019 after a malfunction.

A report prepared by BMR Structural Engineering says the turntable of the crane malfunctioned in May 2019 and a so-called top kit was replaced on the crane’s mast.

The document confirms the crane was certified by an engineer in June and the work site was visited by a Department of Labour officer before post-tropical storm Dorian slammed into the port city on Sept. 7.

However, the document — obtained under freedom of information legislation — does not explain why the hybrid crane collapsed because the findings were almost entirely redacted.

As a result, it remains unclear whether the malfunction had anything to do with the collapse.

This report by The Canadian Press was first published Jan. 4, 2020.
