Wire Rope can be manufactured across the US. Much of the wire ropes created domestically are created in accordance to certain Federal Specifications. This includes Federal specification RR-W-410D which meet the requirements of MIL-W-83420. In addition to many different specifications, Wire Ropes also come in different “lays.”.
Wire rope is made of multiple strands of individual wires which are laid around a support center. The core of these wire ropes are usually created by wire or fiber. The direction in which wire strands are laid during the construction of rope is what determines the “lay” of any given type of wire rope.
The Types of Rope Lays:
Regular Lay
The direction of the lay in “Regular Lay Rope” runs against the direction of the strands. This is preferred when extra resistance and rotation is anticipated.
Lang Lay
The strand lay in “Lang Lay Rope” runs in the same as wire lay direction in the strands. This rope lay offers the most resistance to wear.
Left Lay
The strands on “Left Lay Rope” go from right to left. This rope can be in either Lang or Regular lay.
Right Lay Wire Rope
The strands in “Right Lay Rope” go from left to right. Similar to “Left Lay Rope,” this rope can also be either regular or long lay.
Alternate Lay Wire Rope
The Alternate strands of right regular lay and right lang lay. Combined the best of both regular and lang lay used for boom hoist or winch lines.
