Final answer:
It is generally unsafe to travel with a load raised on machinery, as it poses serious risks such as impaired visibility and load imbalance. Loads should only be raised for stacking or unstacking when the vehicle is stationary to maintain safety.
Step-by-step explanation:
In general, operating a forklift or other piece of machinery with a load raised more than a few inches is unsafe and against standard safety practices. It should only be raised for stacking or unstacking loads when the vehicle is stationary. The concern with traveling with an elevated load includes reduced visibility and load balance which can lead to dangerous situations. For example, if driving with a raised load, any bump or quick stop could cause the load to shift or fall, creating a serious safety hazard. Likewise, a raised load can significantly affect the center of gravity of the vehicle, making it more susceptible to tipping over, especially on uneven ground or when making turns. The protocol under normal circumstances is to keep the load as low to the ground as is safely possible during transport to ensure stability and clear visibility.
