An operator is reviewing a load chart for a telehandler that specifies a maximum allowable forward reach of 10 meters with a 0 kg load. If a 1,000 kg load needs to be lifted, why would the maximum permissible forward reach likely be less than 10 meters for this non-zero load?

Question: An operator is reviewing a load chart for a telehandler that specifies a maximum allowable forward reach of 10 meters with a 0 kg load. If a 1,000 kg load needs to be lifted, why would the maximum permissible forward reach likely be less than 10 meters for this non-zero load?

Answer options: ✅ The increased weight of the load shifts the machine's centre of gravity forward more quickly, reducing stability at greater reaches.

• The hydraulic system loses efficiency and power as the boom extends further out.
• The operator's field of vision is restricted, making precise placement difficult at maximum reach.
• The structural members of the boom become less rigid under load at maximum extension.

Correct answer: The increased weight of the load shifts the machine's centre of gravity forward more quickly, reducing stability at greater reaches.

Explanation: Adding a load to the telehandler significantly shifts the combined centre of gravity further forward. This shift increases the overturning moment, making the machine less stable at a given reach. Therefore, to maintain stability and prevent tip-over, the maximum allowable forward reach must be reduced when carrying a load compared to an empty boom, as per CSA B354.6.
