The carabiner for mountaineering can be used outdoors without climbing. There are also fashionable outdoor tools like carabiners such as key chains, but this time we will feature a strong carabiner that can be used for mountain climbing. Introducing the 10 strongest carabiners carefully selected, as well as the points to determine the shape and strength according to the application!
Choose the shape of the carabiner according to the intended use
A carabiner is an essential item for mountaineering, which is useful for climbing through ropes and slings and gearing. Strength and safety are very important, especially when climbing steep slopes and cliffs, as they support the lifeline Zile. The shape of the carabiner is roughly divided into three. Knowing the characteristics and uses of each will help you climb, lift and lower your luggage, and rescue in the unlikely event!
The most mainstream “offset D type”
A modified version of the D-shaped carabiner in the shape of the letter D. Since it is strong against impact and has a good reputation for strength, the mainstream carabiner used for mountaineering has become the offset D type in recent years. High strength can be obtained because there is a force point that supports ropes etc. in the spinal column (span) on the opposite side of the carabiner opening (gate). It is convenient to clip the rope during rock climbing or use it as a fulcrum.
“HMS (pear) type” with a wide load direction
A type with a different top and bottom width and shaped like a pear. Since the opening is wide open, it is easy to insert ropes and gears. It has a wide load direction and maintains strength, and can be used for difficult climbing and general mountain climbing. The shape is all-round and easy to use, so it is recommended for the first carabiner for beginners.
“Oval (O) type” that goes well with thick tools
An early type of carabiner in the shape of the letter O. Since both corners are semi-circular and wide, it is excellent for mounting wide tools. You can bundle the tools used for climbing and attach them to the harness, and you can also use it for lifting and lowering luggage and rescue. However, keep in mind that the strength is slightly weaker than other shapes, and the threaded rope is easy to move.
I want to identify the strongest carabiner! How to see the strength
Let’s pay attention to the strength and safety of the carabiner in order to carefully select the carabiner that can be called the strongest!
Choose one with UIAA and CE notation
The first thing to look at is whether the carabiner has the UIAA and CE notations. UIAA is a label that meets the safety standards of the International Climbing and Mountain Federation, and CE is a label that meets the safety standards of Europe. This notation is always included in items of famous brands and items sold at mountaineering shops. Not only carabiner but also Zile etc. have UIAA and CE notation, so please check at the time of purchase.
Carabiner strength check
Next, let’s see how strong the carabiner is. The display “kN⇆ number, ↕︎ number, open gate mark number” on the main unit is the load capacity value. kN is read as kilonewton, and the direction of the arrow “⇆” is left and right, “↕︎” is up and down, and “open gate mark” is the state where the opening is open.
In the above carabiner image, it can be read as “kN⇆25, ↕︎10, open gate mark 7”. That is, the left and right strength is 25 kilonewtons, the top and bottom strength is 10 kilonewtons, and the opening is 7 kilonewtons. For mountaineering and climbing, if the left and right strength is 24 kilonewtons or more, you can use it as a fulcrum with confidence.
Pay attention to the fragile load direction
Even with a strong carabiner, there is a load direction (major axis) that exerts the strongest strength and a load direction (minor axis) that is the weakest. With minor axes, there is a risk of damage long before the display strength is reached. While climbing, pay attention to the correct orientation of the carabiner and be careful not to load anything other than the major axis.
Other points to see
Whether there is a safety ring, size, weight, and ease of use are also important points to select the strongest carabiner!
Should I have a safety ring? Lock shape
For dangerous mountaineering such as chains, you need a carabiner with a safety ring that will never pull out the rope. There are two types of lock shapes, and the screw lock type locks by turning the safety ring like a screw. The auto lock type is automatically locked. If the opening is used infrequently or if the rope should not come off, a carabiner with a safety ring is a good choice.
Größe und Gewicht
It is important that the carabiner for mountaineering can be operated with one hand. It is recommended that the size is a size that can be grasped with one hand and the weight is as light as possible. Light aluminum can be used for general mountaineering, but duralumin can be used for hard climbing.
How comfortable is it? Can it be opened and closed with one hand?
The ease of use of the carabiner also affects the safety of climbing. Is it easy to open and close the opening with one hand, and how is it different from wearing gloves? Let’s actually touch and operate it at the time of purchase and check until you are satisfied whether it can be used safely in mountain climbing.
