Collapse of truck mounted concrete pump with boom

21st March 2019

In March 2019, a truck-mounted concrete pump with boom (TMCPWB) collapsed on to an operator.  The injured person had his leg pinned by the boom, causing leg injuries.

Possible contributing factors:

  • Ground under the TMCPWB insufficiently compacted.
  • Underground services not identified. When pressure is placed on underground services such as pipes, they may be damaged causing soil subsidence.
  • TMCPWB not correctly set up
  • Insufficient operator training or experience.
  • Insufficient operator attention to the task of setting up the TMCPWB.

WorkSafe WA's safety alert details how to manage the risks of truck-mounted concrete pumps with booms.
