XLT4

• Low torque| high strength 
• Can be used with a swivel 
• Lower cost than 35x7 
• Can be used at design factor of 3.5 to 1 

XLT⁴ is a revolutionary crane rope design.* “XLT” because it has Extremely Low Torque; “4” because it has the minimum breaking force of a 6-strand XXXXIP (4X) IWRC rope. 

What sets XLT⁴ apart is its unique design which packs more high tensile steel wire into the rope’s diameter, giving XLT⁴ one of the highest strength to diameter ratios ever achieved—with a minimum breaking force 33% higher than standard 6-strand XIP ropes. 

Under load, XLT⁴ generates near zero torque, matching or surpassing the stability of Category 1 35x7 class rotation-resistant ropes. Yet, thanks to its unique design, XLT⁴ is not classified as a “rotation-resistant” rope. It can be used with or without a swivel as a mobile crane hoist rope at design factors as low as 3.5 to 1.

And for value, nothing performs like XLT⁴. Not only does it cost less than a 35x7 classification rope, its compact construction keeps more steel in contact with sheaves and drums for unmatched resistance to crushing and wear—for lower maintenance, less downtime and longer service life.

XLT⁴’s powerful advantages go beyond high strength, low torque and economical cost. With the rope’s high capacity, lifts may be feasible using fewer parts of line—boosting the speed, efficiency and productivity of crane work.

While XLT⁴’s unique construction is different in appearance and feel compared to other wire ropes, you’ll be pleasantly surprised by the way it spools and operates. As with any rope, proper installation is key—particularly for the base layers and all layers that do not come off the drum during normal operation. To maximize performance and avoid “pull-in,” the rope must be spooled on the drum under load, ensuring that the rope is both tight against adjacent wraps and tight around the drum. As with any rope, XLT⁴ will perform better on a grooved drum. XLT⁴ is recommended for all grooved drums and smooth drums with a D/d ratio of 25 or greater.

Although differing in appearance and feel, field experience has shown that XLT⁴ presents no problem in terminations using wedge sockets or wire rope clips. XLT⁴ requires no special end preparation.
