HIGHLINE ALSO KNOWN AS TELPHER TYROLEAN A rope

HIGHLINE • ALSO KNOWN AS TELPHER / TYROLEAN • A rope or rope pulled tight across a chasmor river to facilities the passage or removals patient or equipment back and forth or in one direction.

HIGHLINE • ONE OF THE MOST DANGEROUS AND MOST DIFFICULT VERTICAL RESCUE • INVOKE THE USE OF ADVANCED RIGGINGS SKILLS • ARE ALMOST ALWAYS A LAST RESORT OPTION

HIGHLINES IN RESCUE • IN ALL CASES, THIS TERMS REFER TO A ROPE LINE SUSPENDED FROM ONE POINT TO ANOTHER BETWEEN WHICH PEOPLE, RESCUE SUBJECTS, OR EQUIPMENT CAN BE MOVED

HORIZONTEL HIGHLINES • SUSPENDED FRON TWO POINTS THAT ARE CLOSE TO THE SAME LEVEL

STEEP ANGLE HIGHLINES • SUSPENDED BETWEEN TWO POINTS IN WHICH ONE IS AT A MUCH HIGHER LEVEL THAN THE OTHER.

USES OF HIGHLINES • USED TO TRANSPORT RESCUERS, RESCUE OBJECTS, AND/OR EQUIOMENT ACROSS AN AREA THAT IS A BERRIER TO TESCUES.

1. TO BYPASS AN OBSTACLE USED TO CROSS A DEEP CANYON ORGORGE. 2. TO AVOID HAZARDOUS TERRAIN WOULD BE USED TO BRIDGE A SWIFTLY. FLOWING RIVER 3. TO AVOID DIFFICULT TERRAIN MIGHT BE SUSPENDED OVER AN AREA THAT CONTAINED LARGE BOULDERS OR THICK DEBRIS, WOULD BE DIFFCULT TO MOVE A LITTER. 4. FOR EMERGENCY EVACUATION. EVACUATE PERSONS FROM A HAZARD IN WHICH THEREIS THREAT OF INJURY OR DEATH, AND WHERE THERE IS NO OTHER PRACTICAL MEANS OF EVACUATION WOULD BE A FIRE IN A BUILDING.

ELEMENTS OF A HIGHLINE • • NEAR-SIDE ANCHOR FAR-SIDE ANCHOR MAIN LINE / TRACK LINE LOWERING / BELAYS LINE TAG LINE PULLEYS ( carriage ) REEVE LINE ( ENGLISH/NORWEGIAN ) LOAD

NEAR- SIDE ANCHOR • THE ANCHOR TO WHICH THE MAIN LINE IS INITIALLY ANCHORED. • IN HORIZONTAL HIGHLINE BOTH MAIN LINE ANCHORS WILL BE SUBJECTED TO SIMILAR STRESSES. • IN STEEP ANGLE THE UPPER ANCHOR WILL BE THE ONE MOST SUBJECTED TO STRESS.

FAR-SIDE ANCHOR • THE ANCHOR TO WHICH MAIN LINE ROPEIS ATTACHED ONCE ROPE HAS GOTTEN ACROSS TO THE FAR-SIDE POINT. • MUST BE STRONG AS NEAR-SIDE ANCHOR.

MAIN LINE / TRACK LINE ROPE • LINE THAT SUPPORTS THE MAJOR OF THE WEIGHT OF THE LOAD. • SHOULD BE OF A LOW-STRETCH DESIGN, SUCH AS STATIC KERNMANTLE.

LOWERING/BELAY LINE • RUNS FROM THE NEAR-SIDE POINT AND IS CONNECTED TO THE LOAD, IT SERVES 2 PERPOSES. • TO CONTROL THE SPEED OF THE LOAD THROUGH THE LOWERING DEVICE. • TO HAUL THE LOAD. • BECAUSE OF THE SAG THE LOWERING LINE WILL ACT MORE IN ITS FUNCTION OF A BELAY.

TAG LINE • RUNS FROM THE FAR-SIDE POINT AND IS CONNECTED TO THE LOAD. • TO BELAY THE LOAD. • TO HAUL THE LOAD.

PULLEYS • TRAVELS ALONG THE MAIN LINE ROPE. • AS A CARIAGE. • WITH HIGHER LOADS TANDEM PULLEYS CREATE LESS OF A BEND IN THE ROPE. • SINGLE CARRIAGE/DOUBLE CARRIAGE.

REEVE LINE • ENGLISH REEVE / NORWEGIAN REEVE. • ACT AS LOWERING AND HAULING LINE

ENGLISH REEVE

NORWEGION REEVE

HIGHLINE LOADS • ONE-PERSON LOAD • TWO- PERSON LOAD • LITTER LOADS- SPIDERS - AZTEK ( LITTER SCOOP ) - PERCELL - LITTER TENDER ATTACHMENT AZTEK / PIG TAIL (PRIMARY ATTACHMENT / SECONDARY ATTACHMENT - ETRIER

PROBLEMS OF HIGHLINE • OPTENTIAL STRESS AND FAIRLURE OF EQUIPMNENTS, • TIMEP CONSUMING. • GETTING INITIAL PERSONNEL AND ROPE ACROSS.

DEERMINING THE AMOUNT OF SAG IN THE HIGHLINE • A HIGHLINE SYSTEMS MST NEVER BE STRETCHED TIGHT AND THEN LOADED. • THIS COULD RESULT IN OVER STRESSING AND FAIRLURE OF THE ROPE, ORTHER EQUIPMENT, OR THE ANCHORS.

THE TEN PERCENT RULE • MEANS THAT FOR EVERY LOAD OF 100 POUNDS WITH 100 FEET OF SPAN IN THE ROPE THEN SHOULD BE A SAG OF TEN PERCENT.

EXAMPLE 1. 200 POUND LOAD (1 L) ON A 100 FOOT SPAN 1 L x 100` x. 10 = 10 % FOOT SAG REQUIRED. 2. 200 POUND LOAD (1 L) ON A 200 FOOT SPAN 1 L x 200` x. 10 = 20 % FOOT SAG REQUIRED. 3. 400 POUND LOAD (2 L) ON A 200 FOOTSAPN 2 L x 200` x. 10 = 40 % FOOT SAG REQUIRED.
