Mountaineering is very popular nowadays, and many young people like this challenging sport. But many people get into trouble when choosing starter gear because they can’t figure out what carabiner buckle they should buy as a life safety lock.
The shackles used in early mountaineering were mainly made of steel or iron. The characteristics of steel are strong and durable, with a large bearing capacity, and some can even withstand 4000-5000 kg of tensile force. The disadvantage is that the weight is too heavy, which will increase the load on the climber and cannot be carried in large quantities. Later, such shackles were gradually replaced by aluminum alloy shackles. The normal pulling force of aluminum alloy shackles is 2000-3000 kg. Although it is not as good as steel shackles, it is still enough to ensure the safety of climbers, and it is lighter in weight and easy to carry…
As titanium alloys gradually enter our lives, many manufacturers have begun to produce titanium alloy shackles better than aluminum alloys. The density of titanium alloy is only 60% of that of steel, but its strength is higher than that of steel. Although its weight is not as light as that of aluminum alloy, its strength, corrosion resistance, and heat resistance are better than aluminum alloy. It is an excellent material for mountaineering equipment. The shackle made of titanium alloy is not only lightweight but also has enough strength to ensure the safety of climbers and is favored by many mountaineering enthusiasts.
The carabiner buckle is the most versatile and indispensable equipment in mountaineering equipment. It is a tool used to connect the climber to the main rope, protector, rope, and secure point on the rock wall. The carabiner buckle is a safety guarantee when exploring rivers and climbing rock walls, and many climbing gear combinations and uses require hooks and loops to connect. Any shackle must be strong enough to withstand the shock and pull of a climber’s sudden fall to ensure safety when climbing. But how is it sturdy enough? According to the drop test of “UIAA,” the climbing rope can withstand at least 1200 kg of tension. Due to the braking friction of the rope on the shackle, the load on the shackle should be 1.33 times the load on the rope. For maximum safety in the event of a sudden fall, the shackle must be able to withstand at least a 1500kg impact pull.
Carabiners should not be too heavy. Otherwise, its weight will also lead to increased danger, and carrying a large number of heavy carabiners will also consume a lot of physical energy for climbers.
