Top climbing a tower crane: Ensuring safe assembly and dismantling

Top climbing, a common way of assembling and dismantling a tower crane, is hazardous work that must only be performed by qualified workers.

The importance of tower crane safety was brought to the forefront in July 2021 when a tower crane collapsed while being dismantled at a construction site in Kelowna. As a result, five people were killed, including four workers and a person unrelated to the construction site. Another worker was injured.

The bulletin notes that failure to follow the manufacturer’s instructions may result in a structural failure that puts lives and property at risk. It provides an overview of top climbing, discusses the hazards, employer responsibilities, safe work practices, and legal and regulatory requirements.
