rigging and hoisting
Bowline Knot - ANS-Knot used to form a loop; it is easy to tie and untie, and does not constrict.
\Chain slings are primarily used for____? - ANS-logging industry
\clove hitch knot - ANS-Knot that consists essentially of two half-hitches. Its principal use is to
attach a rope to an object such as a pole, post or hose. Not suitable for anchoring of life-safety
rope
\how can you remove broken wires? - ANS-use pliers and bend back and forth to break off
broken ends
\how can you tell where the weakest part of a wire rope is? - ANS-its worn, broken wires,
unequal stresses in strands, has excessive local stresses or has wear or damage where it
attaches to equipment or fittings!!
\how do you check a ropes diameter? - ANS-at it's widest point, crowns not flats
\how do you inspect a chain for strength? - ANS-by comparing it with its rated length or a new
length of the same type of chain
\how do you inspect on a chain for defects? - ANS-link by link
\how do you perform sling inspection? - ANS-wear to eye and fittings, distortion of fittings, cuts,
holes, snags
\how is fibre rope constructed? - ANS-by a reverse-twisting method
\how much is a ropes strength reduced when knotted bent, hitched and spliced? - ANS-50%
50% 25% 15%
\how often should you check wire rope and wire rope slings? - ANS-regularly, depends of
conditions of their use.
\individual wire, strands and core - ANS-what are wire ropes made of?
\Square Knot - ANS-A knot made of two reverse half-knots and typically used to join the ends of
two ropes of similar diameters; also called a reef knot.
\what are chain hosts used for? - ANS-specifically for vertical lifts because the chain tends to
jam when used at an angle or in horizontal position
\what are metal slings? - ANS-wire rope slings, Flemish eye splice, chain slings and wire mesh
slings
\What are slings? - ANS-lengths of metal, natural fibre or synthetic fibre with various fittings or
loops on their ends
\what are the parts of a chain slip hook? - ANS-eye, neck, throat, saddle
\what are the two main types of rope clips? - ANS-j-clip and U-bolt
\what are two types of blocks? - ANS-wire rope blocks and crane blocks
\what are two types of jacks - ANS-hydraulic jacks and screw jacks
\what are two types of synthetic fibres? - ANS-nylon and polypropylene
\what are types of protection devices for slings? - ANS-buffer strips, reinforcing strips, edge
guards of leather or webbing, sleeves or wear pads
\what are types of softeners? - ANS-wood, metal, pipe with slots, conveyor belting, old web
slings and heavy fabrics
\what are wire mesh slings? - ANS-used where loads are abrasive or hot or tend to cut
