ABOUT WIRE ROPE
Some information about steel cables
Steel wire is now invented by German mining engineer Wilhelm Albert between 1831 and 1834 for use in mining in the Harz mountains in Clausthal, Lower Saxony, Germany.
About the structure of the cable:
A cable is a type of wire consisting of several metal strands placed (or twisted) in a spiral. Originally used forged wrought iron, but today steel is the main material used for the cables
The core of the wire can be a stand-alone cable (IWRC, FC, or CW), in many cases a cable itself. This core provides 10% - 50% (in anti-rotation structures) the strength of steel cables
FC - fiber core
IWRC - Steel core
FC (Fiber Core) - Synthetic resin core
IWRC (Independent Wire Rope Core) - The core is a stand-alone wire
WS (Wire strand Core) - core is cable
The biggest difference in the steel cable is the number of wires, the structure of the wire, the size of the core, and the torsional dimension of the wire.
How to determine cable diameter:
- Diameter of the cable is the largest distance of two tangles (tao) opposite each other.
Today, steel cables are used more widely than ropes or other types of wire because:
- Steel cables have the capacity of greater weight for the same diameter and weight
- The durability and longevity of the steel cable does not change whether it is working in marine or terrestrial environments, in harsh weather conditions.
- Steel cables are more durable and resistant to d
