Which factor can significantly affect crane stability?

Ground conditions significantly affect crane stability because they determine how well the crane can distribute its weight and resist tipping or sinking into softer materials. Stability is crucial when operating a crane, as it relies on a firm and level base to ensure that its load is balanced and secure. Poor ground conditions, such as soft soil, loose gravel, or uneven terrain, can compromise stability.

If the ground is not prepared properly—like being too soft or saturated with water—there's a risk of the crane tipping over or becoming unstable during operations. A firm, well-compacted surface is vital for crane stability, allowing the weight of the crane and its load to be supported adequately without excessive deformation or movement.

While factors like weather conditions, load sway, and operator skill level influence safety and operational efficiency, the immediate and direct impact on stability is predominantly associated with the conditions of the ground beneath the crane.
