Shandong Lisheng Machinery Co., Ltd. is a new generation enterprise dedicated to the hardware industry. It is located in Jining City, Shandong Province, the hometown of Confucius and Mencius. The company is a professional hardware supporting enterprise integrating design, research and development, production and sales. The main products are chains, wire ropes and their accessories: shackles, turn buckles, clips, rings, snap hooks and other forgings and castings, and accept drawings and samples for processing.
Snap hook carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue.
Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most are stamped with a "Not For Climbing" or similar warning due to a common lack of load-testing and safety standards in manufacturing.
While any metal attaching link with a spring gate is technically a carabiner, the strict usage among the climbing community specifically refers only to those devices manufactured and tested for load-bearing in safety-critical systems like rock and mountain climbing, typically rated to 20 kN or more.
Snap hook carabiners come in four characteristic shapes:
Oval: Symmetric. Most basic and utilitarian. Smooth regular curves are gentle on equipment and allow easy repositioning of loads. Their greatest disadvantage is that a load is shared equally on both the strong solid spine and the weaker gated axis.
D: Asymmetric shape transfers the majority of the load on to the spine, the carabiner's strongest axis.
Offset-D: Variant of a D with a greater asymmetry, allowing for a wider gate opening.
Pear/HMS: Wider and rounder shape at the top than offset-D's, and typically larger. Used for belaying with a munter hitch, and with some types of belay device. The largest HMS carabiners can also be used for rappelling with a munter hitch (the size is needed to accommodate the hitch with two strands of rope). These are usually the heaviest carabiners.
Snap hooks are a type of fastener that has a spring-loaded gate. They are often used to quickly and easily connect two items together. One of the main benefits of snap hooks is their ease of use. The spring-loaded gate allows for quick and easy attachment and detachment, making them ideal for applications where speed and convenience are important.
Snap hooks are an important piece of hardware in many industries. They provide a quick and easy way to connect two items together, making them ideal for applications where speed and convenience are important. Snap hooks are also available in a range of sizes and load capacities, making them suitable for a wide range of applications.
Snap hooks are used to make a quick, reversible connection on a system of ropes, or to connect a rope or cord to another component, like a lanyard medallion or barrier post.
All snap hooks and carabiners are designed to be used by people who weigh no more than 420 pounds. The American National Standards Institute (ANSI) requires that all types of hardware designed to protect individuals in falls to have at least a 16 kN rating for the gate and a 22.5 kN rating for the tensile load.
The material of snap hook is usually divided into stainless steel, alloy steel or aluminum alloy. Steel hooks are hard and heavy, and are suitable for attaching anchor points or for contact with sharp metal equipment, such as safety harnesses and descenders. The breaking load of aluminum alloy shackles is not inferior to that of steel products. Aluminum safety hooks are relatively light in weight and are suitable for connecting various equipment of personal protective equipment and carrying multiple spares. However, aluminum alloy is less resistant to cutting, so avoid hooking with other sharp metals when using it.
The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly and reliable operation.
With the development of today's society, the types of chain products are also constantly innovating. The use of chains should be widely used in many industries.
Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grip.
