What should you do when the stacker stops on a slope?

When a stacker stops on a slope, the most effective and safest response is to brake and place the wheel chocks. This action is critical for several reasons. First, applying the brake is essential to prevent the stacker from rolling away due to gravity. Simply relying on the brake without additional measures can lead to failure if the brake system is compromised or if there is a sudden release.

Placing wheel chocks provides an additional layer of security by physically blocking the wheels, ensuring that the stacker remains stationary. In the event of any brake failure, the chocks will help to prevent the stacker from moving down the slope, thereby enhancing safety for the operator and those around them.

Maintaining the wheels straight is important in many operational scenarios, but it does not offer adequate protection against rolling on an incline. Leaving the stacker in neutral undermines safety, as this could easily result in the stacker rolling down the slope. Engaging the parking brake alone, while a good practice, may not provide sufficient security without the use of chocks, especially on a slope where the risk of movement is heightened.
