An operator must lift a 1,800 kg load to a height of 8 metres and a horizontal reach of 6 metres. The load chart for the telehandler shows for that reach and height: Capacity at 75° boom angle is 2,000 kg. Capacity at 60° boom angle is 1,500 kg. Which boom angle should the operator utilize, and why?

Question: An operator must lift a 1,800 kg load to a height of 8 metres and a horizontal reach of 6 metres. The load chart for the telehandler shows for that reach and height: Capacity at 75° boom angle is 2,000 kg. Capacity at 60° boom angle is 1,500 kg. Which boom angle should the operator utilize, and why?

Answer options:

• 60° boom angle, because it provides a lower centre of gravity for the machine. ✅ 75° boom angle, because it offers sufficient capacity for the load.
• Either angle, as long as the load is within the machine's maximum capacity at maximum extension.
• Neither, as the chart indicates instability at these parameters.

Correct answer: 75° boom angle, because it offers sufficient capacity for the load.

Explanation: To safely lift the 1,800 kg load, the operator must select a configuration with a rated capacity equal to or greater than the load. The 75° boom angle offers a 2,000 kg capacity, which safely accommodates the 1,800 kg load, as per CSA B354.7 and provincial OHS regulations.
