Crawler Crane Overturns – Major Safety Alert

Jan 17,2025

A recent safety incident at a residential construction site has drawn attention to the dangers that can occur during the operation of heavy machinery. During the construction of the project, a crawler crane overturned due to ground subsidence. Fortunately, the accident did not cause any casualties, but it resulted in the destruction of the construction facilities and significant delays to the project. This is a reminder for construction companies to implement thorough site assessments and safety measures to prevent similar accidents in the future.

Key elements to prevent a crawler crane from tipping over include:

1. Selecting the right crawler crane:

- Consider the characteristics of the load to be lifted, radius, lifting height and moving area.

- Select a crane that is suitable for the specific lifting operation, ground conditions and space available for access.

2. Siting of crawler crane:

- Ensure the crane is mounted on stable ground and that the ground bearing capacity is sufficient to support the crane.

- Carry out a thorough ground survey to assess the nature of the soil and potential hazards underground.

- Avoid installing the crane near high-risk areas such as open trenches or excavation areas.

3. Foundation design and outrigger support:

- Provide a stable working platform for the crawler crane to travel and operate.

- Use suitable support pads under the outriggers and ensure that the outriggers are fully extended and centered on the support pads to relieve ground pressure and ensure even weight distribution.

4. Maintenance and inspection:

- Regularly inspect and maintain the crawler crane in accordance with regulations and standards to ensure it is in optimal operating condition.

- Monitor the settlement and movement of the crane to prevent potential instability.

5. Safe work systems and personnel training:

- Implement safe work systems for all lifting operations, including planning, preparation, and supervision.

- Ensure that all personnel involved in the operation are adequately trained and understand their responsibilities.

- Proper supervision and coordination of crane movements to prevent collisions and ensure safe operation.

Overall, preventing crawler cranes from tipping over requires careful planning, thorough assessment of ground conditions, proper maintenance and inspection, and compliance with safety protocols and regulations. By implementing these key components, the risk of crane tipping over can be minimized, ensuring safe and successful lifting operations.
