The obvious use is to gain mechanical advantage when lifting heavy objects.
It can also be used to take the strain off another line.
With a rope tail on the block tied to a line with a rolling hitch, strain on the line can be eased in order to,

However, in practice there is a certain amount of friction generated at the sheaves.
Also the length of rope needed to move the load a certain distance will be increased by the number of falls.affiliate links
