For years, JIAOLONG brand ropes have consistently upheld the quality of "Made in China." In our section on work safety, firefighters, workers at heights, water rescue personnel, professional off-road enthusiasts, and rescue teams will find climbing ropes, tow ropes, safety ropes, and lifelines suitable for all types of applications. Our rope selection ranges from those made of polyester or nylon to specialized rope products incorporating high-performance fibers like Kevlar aramid fiber and Dyneema ultra-high molecular weight polyethylene fiber.

Established in 1922, Qingdao Huakai Ocean Technology Co., Ltd. (Hailiya Group) produces various types of rope products that are gradually revolutionizing modern rope manufacturing. The structure of a rope consists of two parts: a core and a sheath (Mantle). The primary advantage of JIAOLONG brand climbing ropes is their ability to absorb energy. They absorb energy by stretching in the event of a fall. Different designs, constructions, and finishing treatments can be used to impart specific dynamic or static properties similar to steel wire ropes. There are two main types of climbing ropes:

- Dynamic Ropes (EN892): High energy absorption and low impact force.

- Low Stretch Kernmantle Static Ropes (EN1891): High strength and low elongation.

Static ropes are ropes with low stretch. Sometimes they are also referred to as "semi-static ropes." Contrary to their name, static ropes do possess dynamic properties, albeit significantly less than dynamic ropes. The working elongation of static ropes is below 5% (compared to 7% to 10% for sport climbing ropes). This means static ropes are fully capable of absorbing a fall; however, we do not recommend using them for this purpose.

Compared to dynamic ropes, the fall arrest is much more abrupt, which can have unpleasant consequences for the user. This is why low-stretch ropes are primarily used for work positioning and rope access systems where dynamic loading is not expected.

Furthermore, there are completely static ropes. These ropes are typically made from materials like Kevlar aramid, Dyneema UHMWPE, or steel. They possess minimal stretch and lack the ability to absorb dynamic energy. For this reason, they can only be used as Personal Protective Equipment (PPE) if employed with an additional energy absorption system. This type of rope is used for lifting heavy loads, for towing, hoisting, rope structures, and pulley systems where minimal stretch is an advantage.

Static Ropes

Low-stretch static ropes are tested according to the requirements of EN1891. This standard defines two types of ropes: Type A and Type B.

Type A are static ropes designed for industrial rope access for persons, including various work positioning and restraint. This also includes rescue work and speleology (caving).

Type B ropes are static ropes with lower technical specifications than Type A ropes (they are thinner in diameter, have lower breaking strength, and are lighter in weight). Consequently, they require greater care and caution during use. They are primarily used in rescue procedures involving descent and rescue devices (e.g., EN 341). JIAOLONG brand climbing ropes comply with both the EU CE mark and UIAA (International Climbing and Mountaineering Federation) certifications, a rare combination among domestic climbing rope brands.

The slings we produce feature a special construction and range in diameter from 4 to 8 mm. They are used as auxiliary cords for pulling lighter loads, establishing anchor points, or as slings. The minimum breaking strength for each diameter is specified in standard EN564.

Special Types of Static Ropes

There are also certain types of static ropes with special designs and constructions. Let's take a quick look at a few of them.

Canyoning Ropes.
Canyoning ropes can be either Type A or Type B static ropes. They are made from different materials. Some ropes use a polyamide sheath for increased abrasion resistance, while a polypropylene core makes them lightweight and buoyant. Others are made with a polyamide sheath and a polyamide core. Full polyamide ropes are heavier and do not float as well, but they can withstand greater static forces than ropes with polypropylene cores. Canyoning ropes often come in luminous colors so they can be seen in water.

Arborist Ropes.
Arborist (tree climbing) ropes have a special construction that differs from other static ropes. They must provide extra abrasion resistance, low working elongation, and good handling. Arborist ropes have a relatively large diameter and a higher sheath proportion. A specially textured sheath construction makes them easier to ascend, and their bright colors make them highly visible. To ensure arborist ropes are easy to splice, they generally feature a braided core.
