WINCH AND SHEAVE

A single sheeve pully has only one wheel a multiple sheeve pully has more than one wheel.

It depends on how you arrange the pullies and what you mean by 'three'.

A pulley block can have 3 sheeves, it would have to be used in conjunction with another pulley block with either 2 or 3 sheeves and rigged to advantage or disadvantage.

Or you could have 3 pulley blocks with a single sheeve in each and each one acts on the hauled part of the other, in tandem.
