Скачать или смотреть Orchard Ladder Gin Pole

This gin pole crane, using a twelve-foot aluminum orchard ladder, takes only a few minutes to set up. There are several advantages to using an orchard ladder. They are lightweight and easily carried to the work site, plus the ladder itself can be used to set choker chain anchor points high up in trees as required.
The hemlock round featured in the video weighs 220 pounds and is lifted easily with the double-sheave blocks. I used a nearby tree as my anchor for the top guy rope, but one could also create a backstop for the legs of the ladder using some steel stakes and a 2x6, and then anchor your guy to a series of steel stakes in the ground, effectively allowing the whole rig to be set up in the middle of a wide open field.
