FIGURE 8 PLATE

With/Without ears
Varying diameters
Tend to twist the rope during use
Once on the rope, difficult to increase friction
Over 75' operations use brake bar rack due to twisting

27

TENSILE STRENGTH

Pulling on a rope in a straight line until it breaks
*bends weaken that area of rope

32

Percentage of rope strength that remains after a knot is tied in the rope

33

Rope Systems
LAFD uses the following knots because of?

STRENGTH
SIMPLICITY
EASE OF UNTYING
after having been loaded

34

ROPE SYSTEMS
OVERHAND

Tie off knots in webbing(seat harness) and in making other knots

35

Rope Systems
MUNTER HITCH

Rope Systems
FIGURE 8 ON A BIGHT

80%
Knot creates a loop at the end of the rope for attaching to anchors, hardware, and other ropes with the use of a carabiner

41

Rope Systems
FIGURE 8 BEND

80%
Tie two ropes of the same size together

42

Rope Systems
DOUBLE FIGURE 8 ON A BIGHT

80%
Strong knot
Two loops reduce the wear and strength loss from the rope bending around the carabiner by splitting the load between two loops

43

46

Rope Systems
OVERHAND LOOP

Used to create a loop in the end of a length of webbing
Strong but difficult to untie

47

Rope Systems
TENSIONLESS HITCH
"NO KNOT"

100%
Have enough wraps around the object so standing end of rope will have no tension on it
Tension of rope is absorbed by the friction of the wraps of rope around the object

48

Rope Systems
NO KNOT
Number of wraps depends on diameter of anchor point and amount of friction it provides

Small diameter requires more wraps
Min 3 wraps

49

Rope Systems
NO KNOT
Rope should not cross over itself

If anchor is above load, rope should be spiral wrapped up with the standing end at the top
