Question

please select the best answer.

select whether the telehandler is stable or unstable based on the lifting scenario:

load weight: 10,000 lbs
horizontal extension: 20 feet
boom angle: 40°

stable
unstable

Explanation:

Locate coordinates on the load chart

Using the horizontal extension of \(20\text{ feet}\) on the horizontal axis (bottom scale) and the boom angle of \(40^\circ\) (radial lines), locate the intersection point on the chart.

Determine the maximum allowable capacity

The intersection of the \(20\text{ ft}\) horizontal reach line and the \(40^\circ\) angle line lies within the zone labeled \(6,000\text{ lbs}/2,722\text{ kg}\).

Compare load weight to capacity

$$ \text{Load Weight} = 10,000\text{ lbs} > \text{Maximum Capacity} = 6,000\text{ lbs} $$

Since the load weight exceeds the safe lifting capacity at this configuration, the telehandler is unstable.

Answer:

• Stable
• Unstable (Correct answer)
