6 x 37 Classification Wire rope

6×37 Classification

More flexible but less abrasion resistant than the 6 x 19 classification. Each strand contains numerous small diameter wires. As the number of wires increases, flexibility increases. 6 x 37 classification ropes contain 6 strands with 27 through 49 wires, no more than 18 of which are outside wires.

*Acceptance strength is not less than 2 1/2% below the nominal strengths listed. †Galvanizing: For class A galvanized wire rope (EIP and IPS grades only), deduct 10% from the nominal strength shown.

WARNING: Any warranties, expressed or implied, concerning the use of this product apply only to the nominal strength of new, unused wire rope. All equipment using this product must be properly used and maintained. Wire rope must be properly stored, handled, used and maintained. Most importantly, wire rope must be regularly inspected during use. Damage, abuse or improper maintenance can cause rope failure. Consult the AISI Wire Rope Users Manual, ASME or ANSI Standards, before usage. Wire rope removal criteria are based on the use of steel sheaves. If synthetic sheaves are used, consult the sheave equipment manufacturer. WARNING!
