GLOSSARY
OF WIRE ROPE TERMS |
Abrasion - Surface wear on the wires of
a wire rope |
Common Strand - Galvanized strand made of galvanized iron wire whose grade is common iron |
Acceleration
Stress - Additional stress imposed on a wire rope due to increasing the velocity
of the load |
Conical Drum - Grooved hoisting drum of tapering diameter |
Aircraft
Cables - Strands, cords
and wire ropes made of special strength wire primarily for aircraft controls
and miscellaneous uses of Aircraft Industry |
Construction - Design of wire rope including number of strands, number of wires per strand and arrangement of wires in each strand |
Alternate
Lay - Lay
of a wire rope
in which the strands are alternately regular and Lang Lay |
Continuous Bend - Reeving of wire rope over sheaves and drums so that it bends in the same direction, as opposed to reverse bend |
Area,
Metallic - Sum of the
cross-sectional areas of individual wires in a wire rope or strand |
Conveyor Rope - Parallel endless wire ropes used to carry material |
Armored
Rope - Rope with individual
strands spirally
wrapped with
flat steel wire |
Core - Member of a wire rope about which the strands are laid. It may be fiber, a wire strand or an independent wire rope |
Back-Stay - Guy used to support a boom or mast: or that section of a main cable, as
on a suspension bridge, cable-way, etc., leading from the tower to the anchorage |
Coring Line - Wire rope used to operate the coring tool for taking core samples during the drilling of a well |
Bending
Stress - Stress imposed on wires of a wire rope by bending |
Cord - Term applied to small sizes of wire ropes |
| Corrosion - Chemical decomposition of the wires of a rope by exposure to moisture, acids, alkalines or other destructive agents | |
Breaking
Strength (aggregate wire) - The sum of the breaking strength in tension of all the wires of a wire rope
when the wires are tested individually |
Critical Diameter - Diameter of the smallest bend for a given wire rope which permits the wires and strands to adjust themselves by relative movement while remaining in their normal position |
Bridle
Sling - A
two-part wire rope sling attached to a single part line. The legs of the
sling are spread to divide and equalize the load |
Cylindrical Drum - Hoisting drum of uniform diameter |
Bright Rope - wire rope
made of wires that are not coated with zinc, tin, or any other protective
metal
|
Deceleration
Stress - Additional stress imposed on a wire rope due to decreasing the velocity
of the load |
Button
Conveyor Rope - Wire ropes to
which buttons or discs are attached at regular intervals to move material
in a trough |
Diameter - Distance measured across the center of a circle circumscribing the wires of a strand or the strands of a wire rope |
Bronze
Ropes - Wire
rope made of bronze wires |
Dog-Leg - Permanent short bend or kink in a wire rope caused by improper use |
Cable - A term loosely
applied to wire ropes, wire strands, and electrical conductors |
Drum - A cylindrical flanged barrel of uniform or tapering diameter on which rope is wound for operation or storage. It may be smooth or grooved |
| Efficiency (wire rope) - Percentage ratio of measured breaking strength of a wire rope to the aggregate strength of all individual wires tested separately | |
Centers - Wire, strand
or fiber in the center of a strand about which the wires are laid |
Elastic Limit - Limit of stress above which a permanent deformation takes place within the material |
|
Choker - Short wire
rope sling used to form a slip noose around the object to be moved or lifted
|
Endless Rope - Rope whose two ends are spliced together |
Clevis -A "U"
shaped fitting with pin |
Equalizing Thimbles - Special type of fitting used as a component part of some wire rope slings |
Clip - Fitting for clamping two parts of wire rope |
Extra High Strength Strand - A grade of galvanized or bright strand |
Come-Along - Device for
making a temporary grip on a wire rope |
