If a forward tipping dumper starts to tip, what should be done immediately?

When a forward tipping dumper begins to tip, the most effective immediate action to undertake is to lower the load and steer into the slope. This technique works to counteract the tipping motion by shifting the center of gravity back towards the vehicle's base, providing greater stability. By lowering the load, the operator reduces the risk of further instability, allowing the vehicle to regain balance.

Steering into the slope helps to align the dumper more securely with the ground, countering the tipping force. This coordinated response is crucial in preventing a complete rollover, which can lead to severe accidents or injury. It is essential to act quickly and correctly in these scenarios to maintain safety and ensure control of the dumper.

Other suggested options, such as shutting off the engine and exiting the vehicle, may seem safe but do not directly address the immediate threat posed by the tipping motion. Accelerating to regain balance can further destabilize the vehicle, and raising the load higher would increase the tipping force, worsening the situation. Hence, managing the load and adjusting the steering as described provides the best chance of preventing a rollover.
