most common wire rope used is Right Regular Lay (RRL). However there are many
equipment applications where Right Lang Lay (RLL) or Left Lang Lay (LLL) are
required. The use of Left Regular Lay (LRL) is minimal and Alternate Lay (Right
Alternate Lay - RAL, Left Alternate Lay - LAL) wire ropes are used in special
applications only. |
||
| RIGHT HAND REGULAR LAY (RRL) The strands are layed in clockwise direction around the core and the wires in the strand are layed in a counter clockwise direction. |
LEFT HAND REGULAR LAY (LRL) The strands are layed in a counter clockwise direction around the core and the wires in the strand are layed in a clockwise direction. |
|
 |
 |
|
| RIGHT
HAND LANG LAY (RLL) The strands are layed in a clockwise direction around the core and the wires in the strands are laid in clockwise direction. |
LEFT HAND
LANG LAY (LLL) The strands are layed in a counter clockwise direction around the core and the wires in the strand are laid in a counter clockwise direction |
|
 |
 |
|
| RIGHT & LEFT HAND ALTERNATE LAY The strands are laid in clockwise direction for right hand alternate lay and in a counter clockwise direction for left hand alternate lay. The wire in the strands for both RAL and LAL are layed in a clockwise and counter clockwise direction in alternating strands. |
