What should be the first step if a crane begins to tilt during operation?

In the event that a crane begins to tilt during operation, the most appropriate first step is to turn off the crane. This action is essential because shutting down the crane can help prevent further instability, reduce the risk of a complete tip over, and ensure that the crane is immobilized while addressing the situation. Stopping all operations immediately allows operators to assess the situation more safely.

Turning off the crane eliminates any potential for additional movement or mechanical failure that could exacerbate the tilt situation. This step creates a safer environment for other personnel in the area and can help to prevent accidents or injuries.

Once the crane is off, other steps can be taken, such as calling for help, alerting personnel, or attempting to lower the load, but the immediate focus should be on securing the crane to prevent further danger.
