Hanger Climbing

    Climbing hanger is made of high strength carbon steel by cold stamping, and then made by strict heat treatment. Product surface is zinc plating or hot dip galvanized. Special outdoor environment and special application purpose can be made of stainless steel. Its strength is higher than that of carbon steel, and it has the function of anti rust and anti-corrosion. High strength carbon steel or stainless steel expansion bolts are required for use. 

    Rock climbing hanger is designed with a circular hole for passing through the expansion bolt. The hanging piece is folded into a 90 degree angle to facilitate the climber to place the foot. The oval hole in the middle is used to pass through the climbing rope. The edge of the oval inner hole is polished and passivated to prevent damage to the climbing rope. According to the diameter of the round inner hole and the size of the expansion bolt, the common specification has the size of M10 and M12. After strict CJ/T 476-2015 tension test, the tensile strength can reach the safety factor of 35-39KN.

这些方便的设备可以帮助登山者在户外岩石上的安全。为了使用锚杆和吊架，攀岩者首先要在岩石表面钻一个洞，然后准备一个膨胀螺栓。这些永久性的保护装置将被放置在岩石表面，并留给其他攀岩者使用。

    These convenient devices can help climbers to be safe on the rocks outdoors. To use anchors and hangers, climbers first drill a hole in the rock surface and then prepare an expansion bolt. These permanent protectors will be placed on the surface of the rock and left to other climbers.Climbing bolt hanger is an important equipment. Climbers use a quick pull device attached to the hanger to provide them with better safety when climbing.

钻孔至正确的直径和深度，然后将螺栓拧入

    Drill a hole with the correct diameter and depth. The expansion of the steel sleeve is then achieved by turning the nut and pull the sleeve to the bolt. Gradually tighten until the nut is tight.The gasket and device are safe. This type usually requires holes to clean thoroughly to make the tapered end bite.

攀登挂片的中心孔特点是有倒角的眼孔边缘，以减少对钩环的磨损。岩石较软或成分不均匀，如砂岩和石灰岩，那么任何岩石锚（包括我们的锚）都不足以承受重载，同时根据基岩材料的强度，选择合适的膨胀螺栓。

     The center hole of climbing hanging piece is characterized by chamfered hole edge to reduce the wear of hook and ring. If the rock is soft or the composition is not uniform, such as sandstone and limestone, any climbing anchor bolts are not enough to withstand heavy load, and the appropriate expansion bolt should be selected according to the strength of the bedrock material.
