| Daniel Murphy demonstrates cutting, rigging, and falling techniques often used by professional arborists in tree removal. Working from the bucket there are close up examples of lowering knots and cuts, as well as using the GRCS lowering/lifting device combined with drift line and spider leg balancers to remove large limbs and wood from over a roof. Viewers may take special note of the falling cuts. Two large spars are dropped across the driveway using padding logs to prevent damage to the asphault. |
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. |
Demonstration of large tree rigging and falling. Tree climber Patrick Epps removes large limbs. Shock loads are reduced by tying limbs and wood near their balance points while skillfully running of the ropes ensures heavy pieces run safely past the climber and swing smoothly into the rigging and stop the same way, minimizing shock load forces. Climber and groundman discuss and execute plan for roping and falling three 100'+ tulip trees seven hours. |
