TreeClimbingSafety

I am a firm believer that progressing as a climber requires being able to properly tie these 21 knots. If you know all 21 of these knots and can do face cuts with no dutchman/bypass then you will be able to remove almost any tree if you are calm and have a decent instructor. 1.) Slip Knot 0:09 2.) Bowline 0:36 3.) Running Bowline 1:30 *4.) bowline with yosemite finish & 6"+ tail 3:20 *5.) bowline with stopper knot & 6"+ tail 4:20 *6.) running bowline with yosemite finish & 6"+ tail (not shown in video) *7.) alpine butterfly (better have 2 long tail's... this is a midline knot) 5:39 *8.) fishermans knots & 6"+ tail 7:06 9.) Clove Hitch 8:16 10.) Cow Hitch 9:29 11.) Timber Hitch 10:53 12.) Girth Hitch 12:30 13.) bowline on bight 13:26 14.) sheet bend and slippery sheet bend 14:50 and 15:30 15.) square knot 15:50 16.) figure 8 16:34 17.) double overhand knot 16:59 18.) Munter hitch (used as alternative to rope wrench) 17:39 *19.) prusik (requires both smaller prusik rope and added friction to be rated for life support) 18:57 *20.) distal hitch (requires both smaller prusik rope and added friction to be rated for life support) 21:06 21.) blake's hitch (same sized diameter rope... depends on who you ask about being rated for life support) 22:40 IMPORTANT: all knots marked with a star symbol * are knots that are rated for life support (Bowline with stopper knot & 6"+ tail, bowline with yosemite finish & 6"+ tail, running bowline with yosemite finish & 6"+ tail, fishermans knot & 6"+ tail, alpine butterfly & you better have 2 long tail's on this mid line knot... I'm not sure exactly on the tail lengths for alpine butterfly's I would always give at least 3 feet of tail to be safe). Both the prusik and distal hitch require added friction (either a moving rope system, munter hitch on stationary rope system, or rope wrench on stationary rope system). Prusik’s and distal hitches need to be tended to occasionally as they can slide from time to time (ALL friction hitches NEED to be tended from time to time). The Blake’s hitch is a company specific policy on being rated for life support or not (it can fail if not frequently tended and redressed); Blake’s hitch requires a split tail the same diameter as the climbing line. Anything life support needs to be rated for 23kN (5400 LBS) The regular bowline is NOT approved for life support. Only with a 6"+ long tail and stopper knot OR a 6"+ long tail and yosemite finish can a bowline be used for life support (should be somewhere in ANSI Z133) The bowline on a bight is NOT approved for life support (I'm not sure why... just do not climb on this knot). #TreeClimbingSafety #Knot #Knots #CTSP #CertifiedTreeCareSateyProfessional #Arborist #5400pounds #23kN #Z133 #Z87 #Rope #Rigging #TreeWork
