STRENGTH​

As the first synthetic line designed specifically for mobile cranes, K-100 is the the lightweight, safe, and reliable alternative to steel-wire rope. Samson has integrated fiber, coating, and rope construction technology from multiple industries to create a hoist line that features a high strength-to-weight ratio, bend fatigue durability, and robust spooling capabilities.

  

 


​SAME STRENGTH AS WIRE ​BETTER THAN POLYESTER/NYLON
The combination of high-performance
synthetic fibers provides strength
similar to steel wire hoist lines of
similar size with same lifting capacity.
It meets or exceeds the maximum line
pull requirements for a 5:1 safety
factor.
​Unlike ropes made with traditional
fibers like nylon and polyester, K-100
is made of high-performance fibers,
which have very low stretch and react
like steel-wire rope. At the max
permissible line pull, the rope has an
elastic elongation of 1.3%.
 

 

 
 
 

 
 
 
WEIGHT​

Weight matters. A 600 ft. spool of K-100 weighs only 154 lbs. compared to 910 lbs. of steel wire at that same length and relative size. Why does this matter? What’s the benefit? That 756 lbs. you lost by using a lighter rope means you can increase your crane’s lifting capacity.

 
In addition, because K-100 weighs 80% less than steel wire, it costs much less to ship and transport. You’ll save an estimated $2,350 on delivery costs with K-100 compared to a shipment of steel wire.
 
Finally, reeving 50 ft. of K-100, at only 11 lbs., is much easier to handle and gentler on the operator’s hands, back, and arms than handling 70 lbs. of steel wire for the same length. Less weight, less effort.

NO STRETCH/NO SPIN​

K-100 is designed with a balanced 12-strand construction, which, unlike "rotation-resistant” steel rope, produces a torque-free product. It’s simple physics: If no torque is stored in the rope, there’s no rotational energy to produce load spin or line twisting. Load spin and birdcage challenges are virtually eliminated. Read the Tech Bulletin: Effect of Twist on Braided Rope.

 
Unlike ropes made with traditional fibers like nylon and polyester, K-100 is made of high-performance fibers that exhibit very little stretch. The first load lift conditions the rope, removing the constructional elongation of 1.3%. After that, K-100 is functionally comparable to wire with no observable difference in the load stability.

EXTREME ENVIRONMENTS

K-100 works well at the extreme ends of both high and low temperatures. However, at the recommended maximum operating temperature of 140°F (60°C), the fiber has a reduced instantaneous strength by approximately 5% to 8%. However, when the rope returns to normal operating temperature below 140°F, the rope’s instantaneous strength returns as well. Instantaneous strength loss will continue to increase at higher temperatures, up to the ultimate melting temperature, 300°F (149°C), of the rope. While it is advisable to keep K-100 out of contact with high temperature heat sources, incidental contact with hot surfaces, such as crane booms exposed to extended periods of sun, will typically only affect the rope’s surface. Please see Samson’s Tech Bulletin “The Impact of Elevated Temperatures on K-100™ Synthetic Crane Hoist Line” for more details. At temperatures below freezing, K-100 gains an additional 10% strength.

 
There are no low temperature limits for K-100.

CORROSION RESISTANCE​

 

Since K-100 is comprised of synthetic material, it will not oxidize or rust as steel wire does in corrosive environments, such as saltwater. Moreover,
K-100 is made of high performance fibers that are highly resistant to corrosive environments. Laboratory and field tests confirm that exposure to acids, bases, oils and greases common* on typical job sites will not impact the strength or integrity of the rope.

*For less common chemicals, it is advisable to check with Samson to verify fiber susceptibility based on exposure testing performed by the manufacturer.
