Which pair of percentages is used to indicate reduced shipping loads on outriggers in different conditions?

• A. 85% and 75%
• B. 60% and 40%
• C. 70% and 50%
• D. 90% and 80%

Answer: (A)

The idea being tested is how crane stability during transport is shown with reduced lift capacities on the outriggers. When a mobile crane is moved, the outriggers and ground conditions limit how much it can lift safely, so charts use two percentages to indicate different transport conditions. The higher value (85%) represents a more favorable condition—solid ground and full, proper outrigger contact—where you can use more of the rated capacity. The lower value (75%) covers less favorable conditions—softer ground, uneven surfaces, or less ideal support—requiring a smaller allowable lift.

So, the pair 85% and 75% matches the typical way manufacturers indicate reduced shipping loads on outriggers for different conditions. The other pairs would imply much larger reductions or don’t align with standard practice for outriggers during transport. For example, if the crane is rated for 20 tons, you’d be allowed up to 17 tons in the favorable condition and up to 15 tons in the less favorable condition.
