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 when the 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.

Galvanized wire and WRI®’s patented one-step impregnation and jacketing process, which provides a thick protective outer layer of plastic, prevents contaminants from corroding the rope and eliminates the need for costly in-field lubrication.

A smooth outer rope profile reduces the chance of entanglement and virtually eliminates dirt buildup, thereby maintaining a more constant T1/T2 ratio. Computer-designed custom ropes ensure accurate rope weights which meet specified T1/T2 ratios.

Factory installed sockets are also available.

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 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.

Bridon Tiger® Half Lock Guide Ropes

Bekaert's Bridon Tiger® Half Lock Guide Ropes deliver high strength along with good resistance to wear and corrosion and reduced stretch.

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® 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 Cushion Pac® Ultra

WRI® brand advanced plastic coated, 8 compacted strand construction

WRI® Tri-MAX

A well-proven 6x27 langs-lay flattened triangular strand construction provides 2.5 times the contact area of a round strand rope. Designed for increased rope strength, wear resistance and fatigue life, and exceptional resistance to drum crushing. The (3/3) triangular strand center construction provides the best strength/performance combination for drums with a recommended D/d ratio of 80/1.
