Conventional rope designs often do not meet the requirements of modern reeving systems, resulting in a shorter service life.
How do CASAR Special Wire Ropes achieve their high breaking loads?
Ropes made from compacted strands have much higher breaking loads and are more flexible compared to those made from conventional strands.
Computer Aided Rope Design (CARD)
With the help of the CASAR-developed CARD (Computer Aided Rope Design) program, the structure of each rope is optimized.
Efficiency and Flexibility
CASAR Special Wire Ropes are designed to provide maximum flexibility. The high flexibility is achieved by a combination of different technologies.
Elasticity and Elongation
What gives CASAR Special Wire Ropes the best stress-strain behavior?
At CASAR, lubrication takes place during the production of both the strands and the ropes.
What is a parallel lay rope?
Under dynamic loads, the plastic layer acts as a buffer or shock absorber and reduces peak loading of the rope.
Why are CASAR Special Wire Ropes so rotation-resistant?
In a conventional rope, an external load creates a moment which tries to untwist the rope and to rotate the load.
Using an active, in-line, anti-friction swivel with the majority of types and classes of wire ropes is detrimental to their service life and can lead to unpredictable conditions during operation. This product bulletin provides the basic reasoning behind why swivels aren't recommended for use with wire ropes except for those that exhibit a similar torque characteristic to that of a category 1 rotation-resistant rope.
