This is called a snatch-block arrangement. It changes the haul rope path
from vertical to horizontal. It also allows you to be a distance from the
tower so you have the haul line, load and tower workers in view at all times.
This is recommended at ALL times. If you're pulling the load up manually, you
can put the rope around your waist and use your bigger leg muscles to pull
rather than just your arm strength. If you're using a lawn mower or tractor,
go in reverse so that you can see everything that's going on.
BTW, commercial crews use mostly hand signals for tower-to-ground
communications including crane loads. They are pretty universal and quite
handy. Especially if you have a lot of noise like your lawn mower or other
power equipment, traffic noise, etc.
