What danger exists when loading large boulders onto a truck with an excavator?

When loading large boulders onto a truck using an excavator, there are several risks involved; however, the concern about the boulders tipping out of the bucket onto the truck is particularly significant. This can occur if the excavator's bucket is not properly positioned or secured, leading to a loss of control over the load as it is being placed. This scenario poses a risk not only for the operator but also for anyone nearby, as the boulders can fall unexpectedly, potentially causing injury and damage.

The design of the bucket and the technique used to lift and place the boulders are critical factors in ensuring that the load remains secure throughout the process. Proper training and adherence to operating procedures can help mitigate these risks, allowing for safer handling of heavy materials. Being aware of this risk and taking necessary precautions, such as ensuring the load is balanced and maintaining a safe operating distance, is essential for safe excavator operation.
