The Deadly Setup: What a Dallas Crane Tragedy Teaches Us About Construction Safety
Crane mishap kills one on Dallas School project
They reviewed the soil conditions under the crane and found that the soil had sufficient strength and compaction.
However, for your projects, perform a bearing capacity check by a geotechnical engineer for any crane or concrete pump truck outrigger that will be used on the project.
Shifting Center of Gravity
The geotechnical investigation determined that the crane was overloaded.
The center of gravity is vital in
operating a crane. When operating a crane, a crane operator should always
ensure that the center of gravity is maintained within the crane’s body to avoid
crane overturn.
Meet with your crane operator and review a lifting plan before work commences.
Consider all the aspects of the lift;
1) Weight
2) Center of gravity
3) Lifting points on the load
4) The path that the load will travel during the lift.
5) Review the capabilities of the crane, review the load tables, or the instrument of loading.
6) Consider the wind
7) Communication during the whole process of the lift.
8) Are the outrigger pads a sufficient size?
