A telehandler's load chart specifies a maximum capacity of 3,500 kg at a 0-degree boom angle (horizontal) when the boom is fully retracted. As the boom is extended horizontally without changing its angle, what happens to the allowable capacity?

Question: A telehandler's load chart specifies a maximum capacity of 3,500 kg at a 0-degree boom angle (horizontal) when the boom is fully retracted. As the boom is extended horizontally without changing its angle, what happens to the allowable capacity?

Answer options:

• It increases exponentially.
• It remains constant. ✅ It decreases.
• It fluctuates depending on ground conditions.

Correct answer: It decreases.

Explanation: As the boom extends, the load radius increases, which places greater overturning moment on the telehandler. Consequently, the allowable capacity must decrease to maintain stability, regardless of the boom angle remaining constant. Ground conditions are a separate factor affecting overall stability, not solely the capacity listed on the chart.
