What do you have to consider when tipping bulk goods?

The selected combination of considerations for tipping bulk goods is correct because both points are crucial for ensuring safety during the tipping process.

1. The vehicle must stand on sufficiently firm ground to prevent instability, which could lead to accidents or the vehicle tipping over during the unloading process.

2. Unlocking the relevant safety devices is essential because it ensures that the tipping bridge can operate correctly and completely tilted without any obstruction or malfunction, which is critical for safe loading and unloading.

The third option, about opening the side walls only when the tipping bridge is in its tilted end position, is also necessary. This is to prevent material from spilling or causing accidents before the bridge is fully tilted.

In summary, all considerations are important to adhere to safety regulations and prevent hazardous situations on the road. Understanding these rules helps promote overall safety in traffic operations concerning heavy goods transport.
