What do you have to consider when tipping bulk goods?

You answered correctly. When tipping bulk goods with a vehicle, it's important to ensure the vehicle is on firm ground so that it remains stable during the tipping process—this prevents accidents or the vehicle from tipping over. Additionally, the safety devices designed to secure the tipping bridge must be unlocked before you start tipping, so the loading area can move freely and completely. This ensures the operation happens smoothly and safely. Remembering these points helps prevent dangerous situations and damage to the vehicle or surroundings. The instruction about opening the side walls only at the end position does not apply in every tipping process and is not always necessary—that’s why it isn’t a correct answer here.
