Do NOT use class 6x37 wire rope attached to a swivel. The rope WILL unlay resulting in an unsafe condition.

Block Twisting (Cabling) will occur when used exceeding certain lifting heights. Call for advice
 
 

Main Applications:
Original equipment rope for many North American and European overhead crane types. Used as main- and auxiliary hoist line on steel mill cranes. Steel Core construction is also used for larger diameter UNI-LOC® Wire Rope Slings. One of the most versatile low strength/low cost rope constructions available.

Rope Characteristic:
Very flexible wire rope with good fatigue resistance, but not as crush resistant as 6x19. In relationship to strand diameter this rope has relatively large outer wires to enhance abrasion resistance.

Fiber Core (F.C.) construction is much more elastic under load (stretch); as such it has a greater energy absorption capability but is even less crush resistant than its cousin with Steel Core (IWRC).

Standard:
ASTM 1023/A 1023M, Table 13
CSA G-4-00
RR-W-410E
EN 12385-4.9
ISO 2408

Class 6x37 wire rope is NOT rotation- or spin resistant.

Selected sizes available in right regular lay (RRL) AND left regular lay (LRL)
     
     
Breaking Strengths
Note: The maximum CAPACITY, WORKING LOAD LIMIT (WLL), or LINE PULL of the rope usually is 1/5 of the below stated values. For specific information consult the standards applicable to your rope application.
