Near Balance Point Rigging 19" Oak Action

Daniel Murphy climbs and dismantles a 19" Oak. This video shows ten lowered climbing cuts. The primary purpose of this video is to show the use of near balance point rigging, where the limbs are tied off close to, at, or slightly beyond the balance point. This allows the climber to use a well cut notch to steer the limbs sideways past other treesa, while reducing shock loads on the rigging as the pieces fall in a slow and controlled path, allowing the lowering line to become nearly or completely loaded before the limbs seperate from the hinge. The near balance of the pieces also allows the ground crew easier handling of the pieces pulling them into a fairly tight landing zone. There is also one bonus cut on the end of a large dry white oak limb being lowered using a the same technique of near balance point rigging, creating a slow and steady movement after seperation. Peter Fixler did the climbing on this last cut, after the lowering line had been set and tied off remotely from the ground.

Nice work. Climb safe!

How does one locate the "Balance Point"? Most Center of Gravity (CG) calculations fail due to the unknown green log weight variations across the span of the length.

Same problem in top-rigging for crane removal and overhead rigging - the dreaded flip we have all seen.

nice ones a the 3:05 and 4:43 marks.

beautiful place to work!

thank you for sharing your video.

Every time you pick up a piece of brush, try picking it up at the balance point.. deadwood is much different ...

@V1d30man

just try picking up a limb on the ground at the balance point til you get the hang of it.. most live limbs have a balance point near 2/3 way from cut to the tip. dead limbs much closer to the cut

I try to loop runner all my knots now. I gain further reach with a steel biner on them to. I gain time with extra ones. I never leve the ground without 2 or 3 at least. Overall that was trees you were lowering down. Not limbs lol. Great job.
