A telehandler has a maximum rated lift capacity of 4,000 kg. The operator needs to lift a 2,000 kg load. On the load chart, for a specific boom angle and extension, the capacity is listed as 2,500 kg. If the operator attempts to extend the boom further than this specific configuration while maintaining the 2,000 kg load, what is the most likely outcome regarding the permissible capacity?

Question: A telehandler has a maximum rated lift capacity of 4,000 kg. The operator needs to lift a 2,000 kg load. On the load chart, for a specific boom angle and extension, the capacity is listed as 2,500 kg. If the operator attempts to extend the boom further than this specific configuration while maintaining the 2,000 kg load, what is the most likely outcome regarding the permissible capacity?

Answer options: ✅ The permissible capacity will decrease, as increasing reach reduces stability.

• The permissible capacity will remain the same, as the load is well within max capacity.
• The permissible capacity will increase, due to better leverage at extended reach.
• The load will automatically be de-rated by the machine's internal computer system.

Correct answer: The permissible capacity will decrease, as increasing reach reduces stability.

Explanation: Extending the boom further increases the forward reach, which shifts the combined centre of gravity of the telehandler and load further forward. This action increases the overturning moment, thus reducing the machine's stability and consequently decreasing its rated lifting capacity for that extended configuration, as mandated by CSA B354.7.
