What are the main reasons for crane overturning?
. Overload
The lifting capacity of the self-propelled boom crane changes with the inclination angle of the boom. The lifting capacity and the inclination angle of the boom should meet the design requirements, and overload operation is prohibited.
In actual work, rollover accidents may occur due to the crane losing its stability.
. Outriggers
The main reasons for crane rollover accidents caused by outriggers:
The ground in contact with the outriggers varies in softness and hardness, causing the outriggers to sink unevenly.
The ground endurance of the crane cannot meet the load-bearing requirements, or the foundation has sunk due to the rainy season.
The support of the outriggers is not standardized, such as: the outriggers are supported on steel plates, supported on loose objects, the outriggers are not fully opened, and the outriggers on the side carrying larger rotations do not have secondary outriggers, etc.
3. Rotation
The main reasons for crane rollover accidents caused by rotation are:
The angle of rotation is on the small side (the position with the minimum bearing capacity).
The rotation movement is too fast and the object loses its stability.
Rotation and lowering or hook-dropping actions are performed at the same time, which reduces the stability of the crane.
