How should the dumper be parked on a slope?

When parking a dumper on a slope, it is vital to ensure that the vehicle is secured to prevent it from rolling. The correct practice involves turning the wheels towards the downhill side. This orientation helps to mitigate the risk of the dumper rolling down the slope if it were to move unexpectedly. By directing the wheels downhill, any potential movement would be contained by the tires against the slope, ideally stopping the vehicle from rolling further and enhancing safety.

In addition to turning the wheels, it is also critical to engage the handbrake and ensure the dumper is in gear if applicable. Parking on a slope requires careful consideration of these factors, as improper parking can result in accidents or equipment damage. The other options provided do not offer the same level of safety and security when parking on an incline.
