About 800 construction workers have staged a protest at a children's hospital site after a major crane accident this week that could have proved fatal.
The Construction, Forestry, Mining and Energy Union said a tower crane terminal fitting, which attaches the crane rope to the jib, failed at the John Holland site in Nedlands on Tuesday morning.
The CFMEU said 50m of crane rope and a two tonne crane block was brought down, narrowly missing nearby workers.
“The workers have had enough,” CFMEU WA State secretary Mick Buchan said.
The CFMEU said the company had verbally agreed to obtain an independent engineer's report into the incident and the operation of another similar crane on the site.
“John Holland reneged, saying no information would be given to the union safety officer Steve McCann representing the workers,“ the CFMEU said.
“Furthermore, any requests for information should now be made through John Holland's industrial relations department, therefore treating the issue as industrial rather than one of health and safety.”
Workers had also reported other operational problems with one of the cranes for more than a month, including regular breakdowns and winch issues, but no investigation had been conducted, the union said.
Comment is being sought from John Holland.
