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