Which option best describes a crane site setup standard?

• A. Ground bearing capacity and levelness.
• B. Ground bearing capacity, levelness, outriggers footprint, mats/cribbing, proximity to hazards, and load path access.
• C. Wind speed and weather conditions.
• D. Operator's experience.

Answer: (B)

Setting up a crane site to standard means verifying the base and surrounding area can safely support lifting operations. It starts with ground bearing capacity and levelness; the soil must support the crane’s weight without excessive settlement, and the surface must be level to keep the crane stable. Then consider outriggers footprint and mats or cribbing; spreading the load over a larger, solid surface reduces ground pressure, prevents sinking, and protects softer ground or finished surfaces. Proximity to hazards is about establishing a safe exclusion zone around the crane to avoid contact with hazards such as electrical lines, edges, pits, or other equipment. Load path access ensures the route for the load from pick to place is clear of obstacles, with adequate overhead clearance and no pinch points, and that the crane’s movements won’t create unsafe trajectories.

Wind speed and weather conditions are important for lifting decisions but are part of the planning rather than the site setup; operator experience matters for safe operation but isn’t a component of the physical site setup standards.
