Before lifting the crane, within how many degrees must it be leveled?

• A. 1 degree
• B. 2 degrees
• C. 5 degrees
• D. 0 degrees

Answer: (A)

Stability hinges on keeping the crane level so the load path stays vertical and the outriggers can support the full load safely. Even a small tilt changes the load line from straight down, creating a horizontal force component that can push the crane or load sideways and reduce lifting capacity. A very tight leveling tolerance—within one degree—keeps these forces minimal and helps prevent tipping or sway as the load is raised. Zero degrees is ideal but impractical on real job sites, and tolerances like two or five degrees introduce too much tilt for safe lifting. So leveling within one degree is the correct requirement.
