The types and the use of the crampon


Many crampons types have different classification methods. From the way of fixation, a tie type (tie type), the difference between full and former cassette cassette tied; from the structure, there are hard and soft, semi hard type; climbing from different uses, high difficulty walking and hiking / snow / ice mix climbing the waterfall.
To talk about lacing and card: card and card slot and crampons only hiking boots collocation. The boots were strong in the bottom, so it can get stuck in order. The bundling range is wide using crampons, can be any type of boots collocation. Tie type wear is slightly off the trouble some crampons. Personally feel that the front tie is the most convenient card type, but requires the boot to have a back slot.
Modern crampons are made of alloy steel with high performance. Frame type hard crampons is generally made of steel sheet in vertical, horizontal direction can not be bent, such as more domestic Trango Harpoon, used for the technical requirements of high waterfall ice and mixed routes; semi rigid steel claw is in horizontal direction, stress conditions, can be a little deformation, for the sole the shape, such as CharletMoser S12, most of the mountain climbing / crampons are of this type; soft can with curved sole crampons, such as CharletMoser Ecrin, can collocation soft soled boots, and even some types of hiking shoes. This is suitable for walking and ice crampons technology requirements of the mountain.
Flat front crampons for climbing and general ice, snow and not too hard for the ice; and the strong penetrativeness crampons due to ice, especially good at dealing with hard, it is the role of the high technical requirements of hard ice and mixed route. When we choose crampons, note that second of the position, the front is the large angle support function better, more suitable for the ice wall is steep, but more to charge some of the strength to walk. For example, CM S12 and Black Ice, the latter second of the more prominent, climbing performance is better.
The stability problem of crampons: some people say that the catch as tied type crampons is stable, easy to fall off. In fact, because is generally not good with boots and crampons. Now most of the catch for the sake of insurance also added a back-up band.
Crampons maintenance: use Ni-Mo-Cr crampons alloy steel, strength and toughness than the conventional carbon steel is good. After use, the sticky ice and snow blocks should be removed so as not to become snow water and corrode the metal and cause rust. Long time use ice tip will be blunted, they will be timely tip by hand rub file, do not use electric wheel, because of the high temperature produced electric wheel will cause the metal annealing. In front of the wire and the cassette crampons must boot if not suitable, coordinated, use a rubber hammer to modify.
Anti climbing ski slopes when wet, snow blocks especially easy to stick between crampons and sole, not long time will form a big wet snowball. It's very dangerous. Once the formation of snowball, should immediately handle to prevent slipping on ice cleaning. The use of anti sticking skis can partially solve this problem. Some brands have a product to sell, there are homemade: find a plastic sheet, than the cut size of crampons can be fixed, crampons on. Anti sticking skis can solve the sticky snow problem to a great extent, but still can not let down.
