How should outriggers be positioned on soft ground?

• A. Partially retracted to save space.
• B. Only one outrigger deployed.
• C. On loose gravel without pads.
• D. Fully extended with level and on appropriate pads or mats; ensure even contact and not over-extended.

Answer: (D)

On soft ground the priority is to create a wide, level, well-supported footprint so the crane doesn’t sink or tip. Outriggers should be fully extended to their designed operating length, placed on appropriate pads or mats, and leveled so all contact points share the load evenly. This distributes the weight, keeps the base stable, and ensures the crane stays within its rated stability limits. Avoid using only one outrigger, as that concentrates weight and increases tipping risk. Placing outriggers on loose gravel without pads is unsafe because the ground can give way, causing instability. The goal is even bearing on a flat, padded foundation, not partial extension or unsupported contact.
