An operator observes that as the boom of the telehandler is extended outwards horizontally, the load radius increases. How does this increase in load radius typically affect the telehandler's lifting capacity?

Question: An operator observes that as the boom of the telehandler is extended outwards horizontally, the load radius increases. How does this increase in load radius typically affect the telehandler's lifting capacity?

Answer options:

• The lifting capacity increases. ✅ The lifting capacity decreases.
• The lifting capacity remains constant.
• The lifting capacity is only affected by the boom angle, not radius.

Correct answer: The lifting capacity decreases.

Explanation: As the boom extends and the load radius increases, the leverage on the telehandler's stability point also increases, reducing the machine's overall lifting capacity. Load charts consistently show that capacity decreases as radius increases for a given height, or as height increases for a given radius. Both boom angle and radius are critical factors influencing lifting capacity.
