1. June 26th, 2022, Dorchester Massachusetts:
- Accident: Mobile Crane Overturns into Building
- Cause: Failure to deploy outriggers before initiating crane operation. The crane tipped over because its load, boom extension, and boom angle exceeded the manufacturer’s center of balance parameters.
- Avoidance: The crane operator, riggers, and supervisors should not have proceeded with mobile crane operations without ensuring that the equipment was properly stabilized. This includes an awareness of the manufacturer’s equipment limits (included in their manual with the equipment) and OSHA safety regulations. With proper training, this accident could have been avoided.
2. January 7th 2019, New York, New York:
- Accident: Mini-crane overturned and fell four stories.
- Cause: The crane operator was insufficiently trained, and thus unaware of its load limits.
- Avoidance: The employer (Western Waterproofing Company Inc.) should have done due diligence in verifying the crane operator’s competence. In avoiding this, they are liable to pay penalties of up to $155,204 for workplace violations.
3. October 14th 2021, Beaumont, Texas:
- Accident: Crane collapsed onto a passing vehicle, killing its two occupants.
- Cause: Employees of Hemphill WBE Pile Driving Company Inc. improperly assembled a crane, by exceeding its load limits, causing it to buckle and land on the passing vehicle.
- Avoidance: The crane operator and occupants present should have been aware of the equipment’s load limits before operation. Measures should also have been taken to minimize or divert movement in the area under the crane.
The Need for Safety Training
Mobile Crane Operator Training
- Pre-use crane inspection
- Signal person hand signal training
- Manufacturer manual interpretation (e.g., load chart training)
- OSHA regulations on proper crane operation and the risks incurred from not following them
- Duties and responsibilities not only to their role, but to other personnel on the work site, such as riggers.
