Slide1

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.

Slide2

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

Slide3

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

Slide4

HORIZONTEL HIGHLINES

SUSPENDED FRON TWO POINTS THAT ARE CLOSE TO THE SAME LEVEL

Slide5

STEEP ANGLE HIGHLINES

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

Slide6

USES OF HIGHLINES

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

Slide7

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.

Slide8

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

Slide9

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.

Slide10

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.

Slide11

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.

Slide12

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.

Slide13

TAG LINE

RUNS FROM THE FAR-SIDE POINT AND IS CONNECTED TO THE LOAD.

TO BELAY THE LOAD.

TO HAUL THE LOAD.

Slide14

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.

Slide15

REEVE LINE

ENGLISH REEVE / NORWEGIAN REEVE.

ACT AS LOWERING AND HAULING LINE

Slide16

ENGLISH REEVE

Slide17

NORWEGION REEVE

Slide18

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

Slide19

PROBLEMS OF HIGHLINE

OPTENTIAL STRESS AND FAIRLURE OF EQUIPMNENTS,

TIMEP CONSUMING.

GETTING INITIAL PERSONNEL AND ROPE ACROSS.

Slide20

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.

Slide21

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.

Slide22

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.
