The reason is speed and heat. If a single barrel machine gun fires too many bullets without stopping the barrel gets hot, very hot, and hot metal goes soft like a chocolate bar and is no longer straight. The speed part is because it takes time to load, fire and clear a chamber for the next round. 6 barrels mean they can load at one point, fire at another and offload at another point. Spinning gives better cooling too.

If you need to move a lot of sand bags 15 feet away it is easier to use 6 people and form a chain than it is to do it yourself. You will use more energy and become tired more quickly, it will also take you a lot longer to move all of the sand bags by yourself.
