35(W)xK7 Compacted Wire Rope
Fully compacted • 16 outer strands • 1960 Grade
The 35(W)xK7 Compacted wire rope belongs in the multi strand, rotation resistant classification but its strands are compacted and is used as hoisting wire rope.
It is very flexible, 3-layer construction and is suitable for use on European crane brands. Most common lay is the Lang’s lay, for multi layer spooling on the winch drum. 2160 tensile strength is also available upon request.
These ropes are usually produced as drawn galvanized and internally & externally lubricated, which makes them corrosion resistant and endurable against the various harsh marine environment factors.
Optionally, these ropes are inner plastified for additional protection against corrosion as the inner core is kept greased and is unaffected by the environmental factors that degrade the rope and reduce its useful service life. Inner plastification adds to safety standards as inspection is very difficult for the inner part of the rope, improves the fatigue life, shows greater resistance to drum crushing, is more abrasion resistant and shows reduced interstrand nicking.
Diligent production processes, raw material selection and quality control in all stages of production ensure a long and trouble free service life.
Attention must be paid on the installation of the new rope on board, its running-in (bedding in) period and load and the inspection before and after every usage.
Compacting technology reduces the size and increases the breaking strength. Please read more on advantages of compacted wire ropes.

Advantages of compacted wire ropes
Bigger metallic area
Higher breaking load thus allowing for smaller diameter 15-20%
Larger surface contact area
Lower contact pressure
Increased resistance to abrasion
Increased resistance to corrosion (due to outer sealing of the strand)
Increased resistance to mechanical damages / vibrations
Increased resistance to shock loading and whipping
Reduction of mechanical stress on both the rope and the sheave, thus extending the life of both the sheave and the winch drum
Decrease of damages between the neighboring wraps in multilayer spooling – Better winding on drums
Significant Cost Reduction due to reduced rope abrasion and increased service life with less maintenance expense
