Cause of death

Severe crush injuries sustained when struck by the boom of an overturned crane

AI-generated summary

Herman Holtz, a 62-year-old tower crane operator, died on 4 August 2016 when crushed by an overturned mobile crane at a university construction site. The crane operator, inadequately trained and unfamiliar with the site, was pressured to move a 10.3-tonne generator using an unsuitable 'pick and carry' crane. Critical safety failures included: failure to conduct risk assessment, improper fitting of the counterweight preventing load monitoring, operating the crane on slopes exceeding manufacturer limits (up to 10.27° vs 5° limit), operating in darkness without adequate lighting, and repeatedly overriding safety alarms. The operator was unaware of a colleague's earlier safety concerns about crane suitability. Multiple organisations failed statutory duties: inadequate operator training, no pre-lift risk assessment, poor site supervision, and failure to use safer alternatives. The investigation and prosecution took 5 years 7 months, causing prolonged family trauma. Systemic construction industry safety culture failures in ACT were evident.

Contributing factors

  • Unsafe operation of crane on unsuitable terrain with slopes exceeding manufacturer limits
  • Operator inadequately trained and unfamiliar with site
  • Failure to conduct pre-lift risk assessment
  • Improper fitting of counterweight preventing load monitoring system function
  • Repeated override of safety alarms despite system warnings
  • Operating crane in darkness without adequate lighting
  • Excessive load height and improper rigging using dragging lugs instead of lifting points
  • Communication failure: operator unaware of earlier safety concerns raised by colleague
  • Pressure from employers to complete task urgently despite safety concerns
  • Inadequate supervision and site induction not conducted
  • Failure to use safer alternative crane (200-tonne slewing crane)
  • Inadequate pre-planning and site assessment by both principal contractor and crane company

Coroner's recommendations

  1. Government should consult with the Court and other stakeholders with a view to reviewing the operation of sections 58 and 58A of the Coroner's Act 1977 (ACT), considering the Victorian Coroners Act 2008 model which vests greater discretion in coroners to manage hearing timing in cases involving related criminal proceedings
