truck - mounted and rough terrain cranes are both forms of a mobile crane, and both use which of the following to increase their stability?

Explanation:

Outriggers are commonly used on truck - mounted and rough terrain cranes to extend outward and downward, increasing the base of support and thus stability. Balance beams are not typically used for this purpose in these crane types. External and internal balance calculators are tools for calculation, not physical components for stability.
