Now in almost every city you can see a lot of high-rise buildings. Often such houses consist of hundreds, and sometimes several hundred floors. Such buildings look quite beautiful and bewitching. But skyscrapers also hide great danger and complexity in their construction and use. To safely create such an amazing miracle, as well as save people from natural disasters, high-quality and durable tools are required.
Carbine DIN 5299
One of the main means is a cable or a rope. Rescuers use them when saving people, and builders use them when building buildings. The ropes are connected to each other by carabiners. It is very important to know that the carabiner must be strong enough to hold a person or not too heavy a load.
One of the best of its kind is the screw carabiner DIN 5299.
Types of carbine
There are several types of this device: a fireman's carabiner DIN 5299C, a fireman's carabiner with a DIN 5299D coupling, a threaded version with a coupling, an animal carabiner (key), which is used to attach a leash to a collar, straps to bags, backpacks, and also type 125 with swivel used for domestic purposes.
Builders and rescuers always use the first type of carabiners, as they are quick-release. Another advantage is that they are equipped with a special latch that will not allow the carabiner to open during operation. It can be threaded or automatic.
Where and how is the DIN carabiner used?
Indeed, this product has no analogues on the building materials market. This is explained by the fact that the DIN screw carabiner has been serving people for many years and is distinguished by its reliability. It is used by almost all builders and rescuers, and especially firefighters. It is very easy to use. In a matter of minutes, a screw carabiner is able to connect any number of ropes or cables. You can connect as one unit, and a group of links. Both a professional and a simple amateur can cope with this with just a wrench. The screw carabiner is made of high quality steel, which is treated with zinc. This type of fixture will never rust.
Zinc-plated screw carabiner can also have different parameters. Neglecting these data when choosing a carbine can lead to dire consequences.
Dimensions and load
The size of the screw carabiner can be from 4 mm to 12 mm. Each size has a specific maximum load. For a 4 mm product, the maximum load is 90 kilograms, 6 mm is 200 kg, 8 mm is 350 kg, 10 mm is 550 kg, and a 12 mm carabiner can be loaded with 750 kilograms.
In order for the screw carabiner to be used as safely as possible, the rope or rope must be strong enough.
The main difference between a screw carabiner and other similar products is that the snap on it is fixed and protected by a special nut, which is tightened with a wrench. But the nut is not just tightened in place: it specifically jumps off the thread in a certain place. This will prevent the carabiner from opening if the thread fails. This fact once again highlights the safety and reliability of using a screw carabiner din.
GOST
Zinc-plated screw carabiner is a fairly small and completely inconspicuous detail that plays a very important role. In order to prevent low-quality goods from entering the market, a special GOST was developed. Each seller is obliged to familiarize himself with it before putting a screw carbine on the window. GOST carbine consists of 8 pages. The first edition of the description of the state standard was published on January 1, 1977. Since then, many changes have been made to this document. The last changes to the document were made on the 6thApril 2015. The official document number is 7041-71.
Unchanging requirements
Despite the many editions of GOST, many of the basic requirements for a carbine still remain unchanged. Several of them can be distinguished: “The carbine must be manufactured strictly according to scientifically developed drawings approved in the developed order”; “The design of a fire carbine must provide high strength and reliability when using a carbine.”
Thanks to these state standards, for 30 years of using the carbine, there were no cases when the operation of the product was unsafe and entailed sad consequences. For unknown reasons, in 2009, the GOST, according to which the carbine was made, was suspended. And only six years later, in 2015, the document became relevant again.
Thus, a fairly small and inconspicuous detail greatly simplifies the work of fire services, as well as builders. If you decide to build a multi-storey building, be sure to stock up on a set of DIN rifle carbines. They will be able to serve you for a long time and reliably, while taking care of your safety and comfort. As for the price, we can say that it is more than affordable. Absolutely everyone can buy a reliable product for such money. It is also worth recalling that when buying a product, be sure to ask the seller for a special document or passport, which indicates that the carbine has passed all the proper tests on the stand intended for this. The seller must have all documentsconfirming the safety of the goods sold. Checking the documents will give you confidence in the reliability of the product.
