The type of crampons

There are many types of crampons, there are different classification methods. From the fixed way, there are tie-type (tied), full card and front-tied card-type difference; from the structure, there are hard, semi-hard and soft; from climbing purposes, climbing / snow walking and high Difficulty waterfall ice / mixed route climbing difference.

Talk about lace and card: full card crampons can only and before and after the card slot with a hiking boots. This kind of boots have a strong midsole, so be able to hold the crampons. While the use of tied crampons is relatively wide, you can match any type of boots. The claws of the claw claws are some trouble. Personally think that the front of the card after the most convenient, but the requirements of the boots after the card slot.

Modern cramps are made of high performance alloy steel. Hard pawl frame is generally made of vertical steel, horizontal direction can not bend, such as the domestic more trango Harpoon, used for high technical requirements of the waterfall ice and mixed routes; semi-hard claws are generally horizontal Steel, the force of the case, can be slightly deformed to fit the shape of the soles, such as CharletMoser S12, most of the climbing / ice claw is this type; soft crampons can be bent with the soles of the , Such as CharletMoser's Ecrin, can be with the soles of the soft boots, and even some types of hiking shoes. This kind of crampons is suitable for glacier walking and technical requirements are not high mountain climbing.

The pre-equatorial pawls are used for mountain climbing and general ice climbing, suitable for snow and not too hard ice; and before the front teeth crampons because of strong penetration, particularly good at dealing with extremely hard ice, its role is technology Requires high hard ice and mixed routes. In addition to the selection of crampons, the need to pay attention to is the location of the second pair of front teeth, the more forward, then the greater the role of support the better, more suitable for steep ice wall, but walking more cost some effort. Such as CM's S12 and BLACK ICE, the latter's second pair of front teeth more prominent, climbing performance is even better.
