ANCHOR SYSTEMS (Pg. 46)
Definition

#1  Double loop, Single loop girth hitch (Lark's foot), Double loop lark's foot, locking larks foot, Single loop basket sling, Single loop, Multi loop

 

A. Types of Anchors:

 

1. Natural (trees, solid rock)

 

2. Manufactured  (Vehicles)

 

3. Structural Components (found in a structure)

 

4. Pickets 

 

Term

#1 Wrap three pull two

 

#2 Double Loop

 

#3 Single Loop Girth (Lark's foot)

 

#4 Double Lark's foot

 

#5 Locking Lark's foot

 

#6 Single loop Basket sling

 

#7 Double loop basket sling 

 

#8 Single sling anchor attachment (open)

 

adv: less sling material required

 

dis: weaker than other slings does not hold position unless loaded. 

Definition

#1 Life line or weebing

stronger than pre-tied slings

Disadvantages: requires longer lengths of materail to form, most complex to form and position, slowest of open slings to form. 

KNOT MUST BE AGAISNT ANCHOR 

 

#2 Pretied, Advantages: quick to form around anchors, easy to relocate, quick to remove, easy to increasethe sling's strength by doubling the loop

 

a. Disadvantage: unable to be adjusted to larger anchors, may be weakened by changes in direction of pull. 

 

#3 Adv: holds position on anchor reasonbly well

 

a. Disadv: overloading may cause the sling to slide against itself, generating enough heat to damage it. 

 

#4 Double Loop Girth Hitch (Lark's foo) Adv: holds position of anchor reasonbly well/ significantly stonger than single

 

a. Dis: overloading causing the sling to slide against itself generating enough heat to damage it. 

 

#5 : adv- holds on anchor extremely well.

 

a. Dis: overloading/heat

 

#6 Adv: does not slide agaianst itself, so no heat generation

 

Dis: if the lenngth of sling is too short it will tri-load the connecting caribiner, decreases strenght of caribiner, does not hold in position unless loaded

 

#7 Adv: stonger than single

 

dis: same

Term
Ladder "A" frames pg. 186
Definition

75 degrees 

 

-Riggged by tying two figure eight on a bight knots with a 12" bights 

 

-knots are 12-18" apart (not greater than 90 degrees)

 

How long are the guidelines?
Minimum of 3x the ladder height (ours were longer if you recall pulling the rope bag all the way across the RTC)


What are the belay line requirements for a ladder gin?
45 degree angle from ladder, 20 feet back



*If the question asks about using the ladder INSIDE the building to make an anchor point the answer is INTERIOR leaning ladder.  If the question asks about using a ladder OUTSIDE the building to make an anchor the answer is EXTERIOR anchor slide.
