Structure Of Climbing Rods
The handle is usually made of EVA, rubber, cork, plastic and other materials, each material has the following characteristics: EVA: comfortable grip, full and elastic, not affected by the season, the material has sweat absorption function; rubber: full grip, hard and easy to crack in winter, no sweat absorption function, easy to handle in summer; cork: full grip, not affected by the season, the material has sweat absorption work. Can, easy to wear and chip; Plastics: poor grip, easy to crack in winter, easy to slide in summer, but low cost, cheap and convenient.
This is the most important part to consider when purchasing a climbing rod, because the mutual transmission between the climbing rod and the user's physical strength is mainly through the wristband, so when choosing a high-quality wristband, we should consider whether it has the following characteristics: the middle of the wristband is wider, the two sides are narrower, which can prevent strangulation; the wristband adjusting buckle is set at the connection with the climbing rod, not in contact with the hand, to prevent wrist scratching; The inner side of the belt is made of suede anti-friction material, which effectively protects the skin contacted by the wristband.
3. Support rod
Aluminum alloy, carbon fiber, titanium alloy, wood, steel and other materials are usually used for supporting rods. Among them, aluminum alloy and carbon fiber are the most widely used. Several materials have the following characteristics: aluminium alloy: strong and durable, low price, heavier weight than carbon fiber and titanium alloy, easy to corrode; carbon fiber: lightweight, good material elasticity and toughness, high strength ratio, corrosion resistance, high price; Titanium alloy: lightweight, good material elasticity and strength, corrosion resistance, high price.
4. Locking system
Locking system is the core safety component of a mountaineering rod. 90% of the mountaineering rod problems are caused by the failure of the locking system. Low-cost climbing rods generally use plastic parts which are easy to change, while high-end climbing rods are made of high-rigidity engineering plastics (crystal plastics) and are precisely cut. Such as the industry recognized advanced locking system, Flicklock joint locking system independently developed by Black Diamond/Black Drill, Robinson patented SLS second generation locking system, Wildview/Di 3LS security locking system, etc.
At the same time, the aluminium alloy climbing rod will be equipped with shock absorber system together with the locking system. As a spring component, the shock absorber system can effectively cushion the impact force and reduce the pressure on the knee when downhill, but because the spring absorbs the thrust when uphill, it will consume extra energy when walking for a long time. In addition, spring components with poor material are prone to rust, fracture, slippage and other conditions, which may lead to locking system snapping or failure. Carbon fibre and titanium alloy climbing rod, because the material itself has good elasticity and toughness, can achieve balanced shock absorption effect without setting shock absorber system.
5. Mud support and mud support
Mud holder can prevent climbing rods from falling into mud, but there are many thorny shrubs in the mountaineering environment, mud holder will hinder the convenience of action, so it should be noted that mud holder can be quickly disassembled and assembled, so as not to cause trouble.
6. The tip of a stick
The rod tips are made of rubber head, iron, carbon tungsten steel, etc. Carbon-tungsten steel is the hardest, the most expensive and the cheapest rubber head, but it can not cope with rugged outdoor terrain, and its wear resistance is not as good as carbon-tungsten steel head. The pattern of the tip of a stick is usually reticulated, diamond and lattice, among which the diamond pattern has the best skid resistance and penetration.
