The figure 6,645 refers to the loader's

• A. Maximum travel speed
• B. Maximum lifting capacity
• C. Payload per hour
• D. Rated hydraulic flow

Answer: (B)

That figure represents the maximum lifting capacity. It shows the heaviest load the loader can safely lift at its rated height and reach, reflecting the machine’s strength and stability limits. It’s not about how fast the machine travels, the amount of material moved per hour, or the hydraulic pump’s flow rate. Travel speed would be given in mph or km/h, payload per hour is a production rate, and rated hydraulic flow is the pump’s fluid volume capacity. Knowing the maximum lifting capacity helps prevent overload and tipping, ensuring safe operation.
