@@Joshua79CA single pole is a Standing Derrick. Two poles is sheer legs and three in a tripod formation is a Gyn. Unfortunately, any time I google Gyn I get the short form for gynaecologist.
The logs being lifted were extremely heavy. Eucalyptus logs that were recently harvested. Lifting anything over 8 feet in length was difficult. The gin pole made every lift fast efficient and safe.
I think the correct term for this arrangement is shears. Nice to see in action.
Before I left for Guatemala I did some research and the name used was gin pole. It is old technology but it really worked well.
They are related but I believe Gin Pole is a single pole with Guy lines. An A-frame is considered shears. See en.wikipedia.org/wiki/Shear_legs
Keith is correct, this is not a gyn pole which is a single with a set of guy lines, i prefer the term a-frame crane/hoist.

I do believe that more energy was used moving the lifting apparatus around in position than the vertical supports.

Would have been worthwhile to get a view of the top of the device.
There is another video that shows the top of the device . . .
Using a gin pole in Guatemala to build a school.
Saturday is for resting
Burr Rabbit true but the Sabbath was created for man not man for the sabbath.
Seems to me that you managed to film it without actually showing the lifting mechanism. Disappointed.
Where is the winch?
It is off to the right, attached to a Toyota land cruiser.
Thousand pound log? What is it ebony? Ironwood? Lignum vitae?
Wet Eucalyptus. Extremely heavy
ebony would be two thousand!
