• Easy rope handling
• Excellent corrosion resistance
• Reliable quality assurance

Bending Fatigue

Relationship between service life of the wire rope the grooves is shown in the figure. Experience has clearly demonstrated that the service life of the wire rope will be materially increased by strict adherence to these standards.

Torque Factor

• Hylift K16, Hylift K18 and Hyfil K18 are rotation-resistant ropes with a steel core closed in the opposite direction to the outer strands.
• When a load is applied, the core has the tendency to twist in one direction while the outer strands tend to rotate in the opposite direction.
• The created moments in the core versus the created moments in the outer strands add to zero over a wide load spectrum.

TORQUE FACTOR OF HYROPE

Bending fatigue in dependence on the groove diameter

According to ISO 4309 the groove of a sheave should have a diameter, that is 5% to 10% bigger thn the diameter. During the operating time, the rope diameter will decrease. With this decreased diameter the rope will dig itself in the sheave groove and will reduce the groove diameter. Therefore, with the installation of the rope it should be considered, that the groove diameter of the sheave is at least 1% bigger than the measured rope diameter. If the groove diameter is too big, the support of the rope is not very good anymore and the surface pressure increases. Consequently the lifetime of the rope decreases steadily with an increasing groove diameter. If the groove diameter is too small, the rope will squeezed and the lifetime d Steel sheaves raps extremely.
