What is the lifting capacity of gasoline-powered cranes?

Gasoline-powered cranes are commonly used for various lifting tasks, particularly in construction and logistics environments. The correct lifting capacities, which include 6,000 pounds, 10,000 pounds, and 20,000 pounds, align with industry standards for cranes powered by gasoline.

The capacities listed in the other options generally do not encompass the upper range of typical gasoline-powered cranes. For example, the combination of four thousand and six thousand in option A would be insufficient for more robust lifting needs that require the capabilities provided by option B. Meanwhile, the capacities in option C, which include eight thousand and twelve thousand, fall short of the higher operational demands often encountered in logistical operations. Lastly, the capacities listed in option D do not reach the maximum lifting capabilities provided in option B, particularly the twenty thousand pounds, which is critical for certain heavy-lifting applications.

Overall, option B reflects the most relevant and practical lifting capacities for gasoline-powered cranes in operational settings, making it the most suitable choice for understanding their capabilities in various logistics and construction scenarios.
