A rough-terrain vehicle is carrying wet cement at a forest road construction site.
To keep the wet cement from spilling due to the vibration, the operator
has raised the bed of the vehicle slightly so that the wet cement is being
carried in the rear of the bed. The vehicle is now going into an incline
of about 20°.
Can you predict what's about to happen?
Look what happened!
When the vehicle tried to climb the forest road with the bed raised, its center of gravity shifted to the rear, causing the front portion of the vehicle to lift off the ground.
The operator, sensing the danger, jumped out, but was flung over the side of the hill and injured.
Tips for preventing similar accidents
1.
Do not operate a rough-terrain vehicle while the bed is raised.
2.
Because it is easy for the center of gravity of liquid loads to become
unstable, take measures to prevent load movement, like installing a partition
in the truck bed. Also, transport such material carefully and at slow speeds.
