A telehandler's load chart shows that at a boom angle of 45 degrees, the maximum rated capacity is 3,000 kg with a corresponding load radius of 6 metres. If the operator extends the boom to reach a horizontal distance of 8 metres while maintaining the same load weight, what can be inferred about the boom angle?

Question: A telehandler's load chart shows that at a boom angle of 45 degrees, the maximum rated capacity is 3,000 kg with a corresponding load radius of 6 metres. If the operator extends the boom to reach a horizontal distance of 8 metres while maintaining the same load weight, what can be inferred about the boom angle?

Answer options:

• The boom angle will increase.
• The boom angle will remain the same. ✅ The boom angle will decrease.
• The load radius will decrease.

Correct answer: The boom angle will decrease.

Explanation: As the load radius (horizontal distance from the centre of rotation to the centre of the load) increases for a given height, the boom angle must decrease relative to the horizontal. An increased load radius means the boom is extended further out and lower. The load radius would increase, not decrease, if the horizontal distance increases.
