Ropes 5 Knots and Hitches Flashcards
How is the Rope measured to get 1 and a 1/2 arm lengths?
Measurement of rope required to form the various knots and hitches is made by stretching the
arms out and holding the rope between the hands. The full distance measured is one arm length. A half arm length is measured by holding the rope in the left hand at the center of the chest and stretching the rope to the right. Note that approximately 6” is allowed to dangle from the right
hand.
What are the uses of the Half Hitch?
The half hitch is used when hoisting or lowering tools and equipment. It is also used as a binder to secure knots.
What shall always be tied in conjunction with the clove hitch unless otherwise specified?
Unless otherwise specified, a binder shall always be tied in conjunction with a clove hitch, except where it is tied away from the working end of the rope (slip-over clove hitch).
The bowline knot is used to hoist ladders of _____ feet and over?
The bowline knot will not slip nor tighten under tension and is easily untied. It is used in hoisting and lowering ladders (20’ and over). The bowline is useful where a loop is needed that will not slip.
The bowline on a bight is used in conjunction with what 2 hitches?
The bowline on a bight is a very important knot. It is commonly used to lower a firefighter to rescue persons trapped at windows which are not readily accessible to ladders. Other rescue purposes include the lifting of persons from excavations, sewers, etc., and the lowering of persons from places where safer escape routes are not available. The bight forms a cradle to support the firefighter and the bowline prevents the rope from tightening or slipping. The bowline on a bight is used in conjunction with a half hitch and a slippery hitch tied about the chest.
What is the becket bend used for?
The becket bend is used to join the ends of two ropes.
When do we use a rolling hitch?
The rolling hitch is used to secure a hose line which has been hoisted via the outside of a building. It is tied directly beneath the couplings just below the edge of the roof or window. The free end of the rope is taken back on roof and secured to some substantial object. The rolling hitch relieves the couplings of the weight of the hose.
How many inches from the end of the handle do you tie the half hitch when tying a pull down hook?
Tie a clove hitch and binder on handle close to metal. Bring working end of rope around top of
hook and back to handle end. Tie a half hitch around handle about 12” from the end. The hook is placed in position on the object to be pulled; a strain is kept on the rope and the firefighters move back to the working position.
