Understanding a Steel Cable

 

Steel Cable

By Anne Ahira

There are different types of cables that have their own productive uses to help accomplish certain tasks. Ordinary cables are generally flexible and quite durable for them to be used for all sorts of occasions.

When there is a need for added durability and toughness, a steel cable could be used instead and depending on the type, the steel cable may be flexible as well just like any other cable or rope.

Also known as a wire rope, these steel cables have a long history and have evolved to be useful in many ways.

History of a Steel Cable

Steel cables had European beginnings way back in the 1600s, but they were put to use a few centuries later. Prehistoric techniques served as an inspiration to the way these steel cables are actually made.

Albert Ropes practiced on making these steel cables by hand, but had problems in the flexibility at first. The primary use during those times was to use them for hoisting to replace the unstable chains and deteriorable hemp ropes.

Through succeeding years, the construction of the steel cable changed and even patents were filed for certain techniques and strands used to make the steel cable. Steel remains as the primary material in making these cables replacing the previous material which was wrought iron.

Understanding the Current Specs of a Steel Cable

When browsing through steel cables in online retailers like Amazon.com, each item is usually listed as a title that indicates the material type and some numbers like 1×7 or 7×7. These numbers are important for the tasks that the steel cable can handle.

The first number is the number of strands used to compose the rope while the second number is the amount of wires that compose each strand. Every steel cable being sold also has a length and strength measured in pounds.

Buying Guide

Always look at both the screenshots of the steel cable and the specifications. If the cable will be used for a very critical task, be sure to ignore all steel cables being sold that have lacking specifications. Titles that try to squeeze in all the details are good links to click first.

See if the material type is listed along with the exterior finish to determine the overall quality. Then Look at the standard construction, breaking strength, and diameter to get an idea of how tough the cable is.

If the steel cable will be used for hoisting heavy objects, the breaking strength must be greater than the weight of the object that will be lifted. Galvanized steel is a good material as it is highly resistant to rust.

Amazon is a great place to get steel cables because the price is low and shipping costs are usually free.



Choosing a Gitzo Tripod

Gitzo Tripod

By Anne Ahira

Tripods are a necessary piece of equipment if you want to get great photos or videos. They can be big and cumbersome to carry around, but the end result is so worth the effort.

A Gitzo tripod can help eliminate camera shake that ruins many a family photo, or the jerky motion of an amateur video. Nevertheless, what should you know about choosing the right Gitzo tripod?

Sturdiness

A tripods main function is to steady your camera equipment, so the tripod itself must be sturdy. Check the stability of a tripod by applying significant pressure while the legs are fully extended. If it does not wobble or shake then it is made of good material and should stay put when you are using it.

Weight

There are two weight issues to consider with a Gitzo tripod, first is the actual weight of the device and second is how much weight it can support. Both are crucial factors to consider when purchasing one for the first time.

Weight of the tripod will vary greatly depending on the size and materials it is made of. Choosing the right weight for you depends on where you will use your equipment and how much weight you can bear for how long.

If you want to test the numbers before you buy grab some cheap weights and add them to a bag, then carry it around with you under the same circumstances you would be using the tripod.

Once you are finished, realize the length of the tripod when folded will compound the weight.

The other weight issue is much simpler to deduce, you can read the specifications of the Gitzo tripod you are considering and then compare that figure to the weight of the camera and lenses you want it to support.

Never use heavier cameras than your Gitzo tripod is rated to support, you could damage both pieces of equipment and as you know neither come cheap.

Height

Lastly, how high does the tripod extend? You will want to be sure the tripod will extend as high or low as you need it to go depending on your photography subjects.

It should also fit you well, you do not want to be bending significantly all day long for an average height shot, that would be a real pain in the neck. The folded length is also important, the longer it is the more difficult it will be to tote around.

Bottom Line

Gitzo tripods come in a variety of constructions and combinations. Some will offer removable heads for those who prefer ball to pan and others will not.

The bottom line is you must consider all the options pertinent to your hobby or business before making a purchase.
