What is the carbon percentage in wire ropes?
Wire Ropes The standard grades have typical carbon content ranges as follows: iron rope −0.05% to 0.15%, traction steel −0.20% to 0.50%, mild plow steel −0.40% to 0.65%, plow steel −0.65% to 0.80%, and improved plow steel −0.70% to 0.85% (American Society for Metals 1948).
What is minimum breaking force of wire rope?
The minimum breaking load describes the maximum force under straight pull a free length of rope can be exposed to until it breaks. It is specified in daN or kN. The minimum breaking load for ropes required under EN 1891 A is 22 kN.
What does Iwrc mean in wire rope?
Independent wire rope core
IWRC = Independent wire rope core.
What is the strength of wire rope?
These wire ropes come in fiber core or IWRC variations with diameters ranging from ¼ to 1 1/3 and tensile strengths of 2.74 tons to 69.4 tons.
What is Epiwrc?
Definition 8xK26WS-EPIWRC: The compacted exterior wires make for a larger metal section, and increased resistance to abrasion and crushing. Their multiple uses include: Mobile port cranes, container ship cranes, etc. Not suitable for working with swivels.
What are the fill factors of Casar wire rope?
The fill factors of Casar Special Wire Ropes are in general considerably higher than the fill factors of conventional ropes. BREAKING LOAD 4:Breaking loads of steel wire ropes when tested on sheaves, depending on the ratio sheave diameter/rope diameter. The factors of safety cover the reduction of the breaking loads.
Why are Pfeifer wire ropes made of parallel strands?
Premature damage may be the consequence. JParallel stranding method (fig. 8) All wires are arranged parallel in the strand structure thus a continous linear contact is provided. The result is a reduction of compressive stress of the wires. Therefore many of our special ropes for running service are made of parallel stranded strands.
What kind of wire is used in rope?
It was obvious from a very early stage that the structure of the strand in particular has a great influence on the characteristics of the rope. Over 100 years ago the Seale, Warrington, Filler wire and the cross lay (formerly called standard) wire configuration were already well known.
What makes up the core of a rope?
The core of the rope consists of natural (NFC) or synthetic fibre (SFC). Fibre cores (fig. 1 and 3) store lubricants, support the strands and dimish vibrations. Steel core (WC) There are two typical types of steelcore 1. Wire strand core (WSC) The core of a round strand rope consists of a strand (fig. 4). 2. Independent wire rope core (IWRC)
