Question

please select the best answer.

which is the best load handling technique?

drive with the load raised high for better visibility
retract the boom first before lowering it
lower the load with the boom extended
none of the above

Explanation:

Analyze stability principles for boom operations

$$ \text{Center of Gravity (CG) stability} \propto \frac{1}{\text{Boom Extension}} $$

Lowering or moving a load with an extended boom increases the load moment, shifting the combined center of gravity forward and risking a tip-over.

Evaluate the given options

• Driving with a raised load raises the center of gravity, destabilizing the vehicle.
• Retracting the boom first keeps the load close to the machine's stability triangle before lowering, which is the safest practice.
• Lowering with the boom extended maximizes the tipping moment.

Answer:

• Drive with the load raised high for better visibility
• Retract the boom first before lowering it (Correct answer)
• Lower the load with the boom extended
• None of the above
