Fastening chains
Any cargo that is intended for transportation, especially long-term transportation, must be secured with special devices. For these purposes, fastening chains are used. This is quite relevant when transporting goods by sea or river vessels, as well as by trucks.
Features of fastening chains
The fastening chains are a mechanism made of high-strength round-link load chain and equipped with hooks at both ends. Features of such equipment include:
a large margin of safety is ensured thanks to large metal links;
Can be used in combination with other fastening devices.
Chain tension is achieved through the use of a chain lanyard with a ratcheting mechanism. The main characteristic of chains is the breaking capacity of the device. Therefore, when choosing such fasteners, it is necessary to opt for those that have a load capacity twice as large as this indicator.
How to choose fastening chains
In 2021, there is a huge selection of fastening chains on the market. You can purchase a device of different lengths and working loads. The choice of chains depends on the characteristics of the load that needs to be secured:
weight;
dimensions;
form;
number of attachment points.
Types of chains for securing loads
There are several main types of fastening chain devices:
chains that ensure the safety of cargo transportation by road and rail;
chains for securing timber in a stationary state when transporting it by timber carriers, as well as other goods when transporting them by sea;
choker chains for forest skidding.
Production nuances
Fastening chains are produced in factories. In European countries and the United States of America, this process is controlled at the legislative level. In these states there is a special bulletin that is issued by the Ministry of Transport. This document regulates the requirements for ready-made fastening devices, as well as the conditions for their use. Therefore, large industrialists or specialized organizations are engaged in the production of fastening chains.
In our country there is no such legislative regulation, and therefore many enterprises are trying to produce fastening chains. Most of them, in the race for volume, neglect quality.
