6 strands wire rope with fiber core has a long history of 40 years, which is one of the very common hoist ropes.
Advantage:
A large section of wires, so the broke strength is higher under the same diameter Permanent tension and elastic elongation are the small Unit lengths of lower price
Defect:
Larger steel wire diameter, less flexible, the bending fatigue life is short Contact points between race and rope are less. Higher pressure
8 strands wire rope with a fiber core is the most common elevator rope undoubtedly
Advantage:
Compared with the 6 strands, 8strands rope is rounder The section can be deformation, so the new wire rope can adapt little worn string slots. Smaller diameter steel wire, which has high flexibility and good fatigue resistance Unit length moderate price
Defect:
Permanent elongation and elasticity are larger, which can cause steel wire diameter reduced greatly. The quality of wire rope is too dependent on the quality of the wire core.
Summary:
It is the best choice for common traction-type elevator wire rope.
8 strands steel wire rope with steel core
Advantage:
Compared with the 6 strands, 8strands rope is rounder. Smaller diameter steel wire, which has high flexibility and good fatigue resistance Permanent elongation and elasticity is smaller Higher break strength unit diameter. Can keep the circular, suitable for wide incision of the wheels of the race.
Defect:
ecause keep the circular, don’t apply to mild wear wheel slots Unit length price is higher than fiber core. When installation, pay attention that wire rope should never be allowed to spread out In order to prevent the rotation, the end must tighten
This steel wire rope is invented in 1955, Gradually widely used all over the world in high-end elevators.
Advantage:
Section very round, namely on rope slot pressure small. More steel wires, more flexibility, Bending fatigue life is long. One of the reasons is because the specific structure of wires in strands and ropes can avoid the steel wire cut overlapping can prevent such internal not visible steel wire rope breakage
Permanent extension and elastic elongation small, so the elevator compartments can connect with the host better. The layer is high precision.
Defect:
Because keep the circular, don’t apply to mild wear wheel slots Unit length price is higher than fiber core When installation, pay attention that wire rope should never be allowed to spread out. In order to prevent the rotation, the end must tighten
Summary:
Apply to the super-tall elevator. Apply to the elevator with multiple guide wheels.
