Steel chains & Stainless Steel Wire Rope are all around us and along with other essential marine stainless steel products they are mostly used in loading ships. These creatures are little understood and terribly abused. Just because they are steel, does not mean they are indestructible. They may not be as feeble as your jewellery chain accessories, but they too need to be cared for to ensure that they are used to their maximum potential. And more importantly, safely load stuff on and off the ship without any accidents and injuries. But to do that, we need to understand a bit more about these steel chains & wire rope.
Stainless Steel Wire Rope are created in a similar way regular ropes are created. Strands of natural or synthetic fibers are twisted together to form a sturdy rope. In case of wire ropes, the same thing is done with metal wires. There is usually a core of metal or fiber, on top of which, multi-wired strands are wrapped around to form the wire rope. The core plays an important role in the strength and flexibility of the wire, but so does the strand composition. The number of wires that will make a strand and the number of strands that will make a rope all account to how the rope will behave. It takes very experienced people to choose the correct rope configuration for the right task. With so much choice, decision can be quite tough.
Stainless Steel Wire Rope can be classified into two types, depending on the way the wires are laid - regular lay and lang lay. In the regular lay type, the strands are laid in such a way that the wires in the strands are in the opposite directions of the strands. That is, the wires are parallel to the rope's axis. For example, the wires are laid in horizontal direction, while the strands are twisted in the vertical direction. For lang lay, the direction of the wires are the same as the direction of the strands. That is, they are both in the vertical direction, at an angle to the rope's axis. The former type is more flexible and has a greater compressive strength than the lang type. The lang lay type of rope can be used only where both ends of the rope is fixed. The sub divisions in these two types are: right lay and left lay, where the strands are either twisted in the right direction or the left direction. They do not have any substantial effect on the strength and flexibility.
To ensure that your wire ropes last longer, take care of the followings details.
• Each type of wire rope has a particular amount of safe load, that is, the greatest weight it can carry which also depends on the efficiency of the end attachment. Make sure you do not exceed that weight.
• The wire ropes have to pass through sheaves (a wheel like contraption) to aid in easy loading and unloading. Make sure that the sheaves are comfortably larger than the rope's diameter. This will deter any corrosion and prolong the life of the rope.
We often tend to take those for granted who work the hardest. Steel chain & Stainless Steel Wire Rope and other marine stainless steel products too aid us silently, take care of them.
