An operator is instructed to use a jib attachment for an overhead lift. Upon connecting the jib, the machine's load chart display automatically changes, showing a significantly reduced lifting capacity compared to using forks. What is the reason for this change?

Question: An operator is instructed to use a jib attachment for an overhead lift. Upon connecting the jib, the machine's load chart display automatically changes, showing a significantly reduced lifting capacity compared to using forks. What is the reason for this change?

Answer options:

• The jib's weight adds to the overall load, reducing available capacity. ✅ Jibs typically have a higher centre of gravity and longer load distance than forks, which decreases stability and lifting capacity.
• The jib attachment itself is structurally weaker than the standard fork carriage.
• The machine's software automatically defaults to a lower capacity for all alternative attachments.

Correct answer: Jibs typically have a higher centre of gravity and longer load distance than forks, which decreases stability and lifting capacity.

Explanation: Jibs extend the load further from the machine's front axle, increasing the load moment and reducing the lifting capacity due to the principles of leverage and stability. The telehandler's load sensing system recognizes the attachment and adjusts the load chart accordingly.
