What type of ground should an excavator be parked on to ensure safety?

Parking an excavator on firm level ground is crucial for maintaining safety and stability. This type of surface provides a solid and even base that minimizes the risk of tipping or sliding, which can occur on less stable surfaces. Firm level ground helps to distribute the weight of the excavator evenly, reducing the chances of ground deformation or equipment failure.

On soft and uneven ground, the excavator could sink or become unstable, which poses serious safety risks. Loose gravel does not provide the required support and can shift under the weight of the excavator. Sandy surfaces can also lead to instability as they tend to shift and may not support heavy machinery well. Therefore, the most secure option for parking an excavator is firm level ground, which ensures safe operation and reduces the risk of accidents.
