How does the centre of gravity of a load affect the method of securing the load?
Show the correct answer
Correct answer
B. The high centre of gravity of the load may require the use of additional techniques to secure the load.
Explanation
The question is about how the position of the load's centre of gravity affects the way the load is secured. A high centre of gravity may require the use of additional securing techniques - answer B.
The Road Traffic Act requires that the load does not affect the stability of the vehicle and is secured against shifting. The higher the centre of gravity, the greater the tipping force acting on the vehicle combination in a bend, when going around an obstacle and when braking - that is why a high load must be secured more carefully: with additional lashings, locking bars and anti-slip mats, and sometimes you need to slow down in a bend more than a warning sign or the speed limit suggests. Answer A contradicts physics, and answer C is dangerous: even a load placed low must be secured, because in sudden braking it pushes forwards with a force of up to 80 percent of its weight. The rule is simple: the heaviest items at the bottom, close to the longitudinal axis, and the whole load held in place with straps protected against loosening.
