A concrete panel weighing 1,800 kg has a very large surface area. A telehandler with a maximum load capacity of 2,500 kg at the required reach is attempting to lift it. The manufacturer's load chart typically does not account for wind resistance. If the wind speed is 40 km/h, what is the primary stability concern?

Question: A concrete panel weighing 1,800 kg has a very large surface area. A telehandler with a maximum load capacity of 2,500 kg at the required reach is attempting to lift it. The manufacturer's load chart typically does not account for wind resistance. If the wind speed is 40 km/h, what is the primary stability concern?

Answer options: ✅ The large surface area of the panel will act as a sail, drastically increasing the effective load and potentially causing lateral tipping.

• The telehandler's hydraulic fluid will overheat due to the increased resistance.
• The engine will stall because of the additional power required to lift against the wind.
• The panel will rotate uncontrollably, regardless of wind speed.

Correct answer: The large surface area of the panel will act as a sail, drastically increasing the effective load and potentially causing lateral tipping.

Explanation: Loads with large surface areas, such as concrete panels, create significant wind resistance. This resistance generates a lateral force that can exceed the telehandler's lateral stability, effectively adding a 'side load' that is not accounted for on the load chart, and can lead to lateral tipping. This is a critical consideration under CCOHS guidance and provincial regulations related to crane and heavy equipment operations.
