PS 3410

A well-proven 34x7 construction provides good flexibility multi-strand spin resistance allows for smoother in-service operation, reduced rope torque, and less movement in the shaft.

A specialized Line Contact Design (LCD) improves performance and reduces internal cross cutting damage, common to other multi-strand products. By combining outer langs-lay strands with inner regular lay strands, the underside of the outer strand wires run in the same direction as the wires of the supporting layer. A specially manufactured core improves rope performance by reducing stretch, providing a more consistent density and diameter to support the strands, resisting strand abrasion, and eliminating core rot caused by corrosive environments.

WRI® DyPac 18

WRI® DyPac 18 series is a compacted rotation resistant rope construction consisting of an inner rope laid in one direction and an outer layer of strands laid in the opposite direction.

WRI® Ultra

WRI® brand rope without a plastic coating, Ultra is available in 6-strand design for drag position and 8-strand configuration for hoist position.

WRI Surelift® 35

WRI Surelift® 35 is a high performance, compacted low rotational rope that combines various multistrand designs to achieve excellent rotation resistance in high lift operations.

WRI Cushion® 34

A 34x19 construction provides improved flexibility and an approximate natural loop to rope ratio of 45-1. Multi-strand spin resistance and plastic enhancement allow for smooth in-service operation, significantly reduced rope torque and stretch, and less movement in the shaft whenthe rope is at full speed. Full plastic impregnation improves spin-resistance and eliminates internal cross cutting of the strands which is common to other multi-strand products, thereby extending service life and improving security. Galvanised wire and WRI's patented one-step impregnationand jacketing process, which provides a thick protectiveouter layer of plastic, prevents contaminants fromcorroding the rope and eliminates the need for costly in-field lubrication.

WRI Cushion Pac® Ultra

WRI® brand advanced plastic coated, 8 compacted strand construction

WRI® DyPac 34

DyPac strand enhancement of a 34x7 (LCD) construction provides additional performance, an increase in strength of approximately 15%, reduced sheave and drum wear, and significantly enhanced drum spooling. As a result, operating depths can be extended up to approximately 6000 ft. (1830 m).

WRI Power-Loc® HLC

WRI Power-Loc® HLC guide and rubbing ropes have five decades of proven track record. A specially designed half-locked coil construction provides excellent rotation resistance, superior wear properties and minimal movement in the shaft when compared to other rope constructions. Locked coil rope guides provide a cost-effective alternative to rigid wood or metal guides by allowing for reduced shaft sizes and structures, improved air displacement on moving conveyances and minimized damage and wear caused by vibration.

WRI® DyPac 6

WRI® DyPac 6 is a high performance compacted single layer rope construction for various cranes and industrial applications.
