Which of the following is a crucial factor in crane setup near excavations?

Ground stability is a crucial factor in crane setup near excavations because it directly affects the safety and operational capability of the crane. When a crane is set up near any excavation, the underlying soil or ground condition is critical in supporting the weight and load of the crane, as well as the materials being lifted. If the ground is unstable, it can lead to settlement, tilting, or even collapse of the crane, posing significant risks to workers and potentially causing damage to the equipment or surrounding structures.

Stability is assessed by considering factors such as soil type, moisture content, and any alterations made to the terrain, like digging or excavation. Ensuring that the ground can adequately support the crane's load and that proper precautions are taken—such as using mats or choosing a location further from the edge of an excavation—can significantly help mitigate risks associated with crane operations.

While proximity to power lines, distance from other equipment, and visibility of the area are also important considerations when setting up a crane, they do not have the same direct impact on the operational stability and safety of the crane as the stability of the ground itself.
