A telehandler's load chart specifies a maximum capacity of 3,000 kg with a fork attachment. The operator needs to use a truss boom attachment that weighs 350 kg. If the load chart for the truss boom attachment indicates a reduced rated capacity, what action must the operator take when calculating the safe working load?

Question: A telehandler's load chart specifies a maximum capacity of 3,000 kg with a fork attachment. The operator needs to use a truss boom attachment that weighs 350 kg. If the load chart for the truss boom attachment indicates a reduced rated capacity, what action must the operator take when calculating the safe working load?

Answer options:

• Subtract the weight of the truss boom from the original 3,000 kg fork capacity. ✅ Refer only to the specific load chart for the truss boom attachment.
• Add the weight of the truss boom to the load being lifted.
• Assume the 3,000 kg fork capacity is still applicable as long as the total weight is less than that.

Correct answer: Refer only to the specific load chart for the truss boom attachment.

Explanation: When using any attachment other than standard forks, the operator must always refer to the specific load chart provided for that attachment. Attachments significantly alter the telehandler's centre of gravity and leverage, often reducing its rated capacity. Subtracting the attachment weight from the original fork capacity or assuming the original capacity is still valid would be incorrect and unsafe.
