The origin of drag chains
Drag chain, also known as electric Cable carrier drag chain (Cable carrier), is a device that bundles cables or air pressure pipes and oil pressure pipes to facilitate their rotation and movement.
In 1953, Professor Gilbert Waninger from Germany created the world's first steel drag chain. Waldric, the owner of KABELSCHLEPP, a company founded in Siegen, Germany in 1954, believed that cable drag chains were a brand-new upgraded market that could create a huge demand and began to promote drag chains to the market. A concept that emerged over 60 years ago has given rise to today's vast market.

Today, the original design of steel drag chain samples has developed into various types of steel and plastic drag chains, which are used in many industries. KABELSCHLEPP, a company founded by Kabelschlepp, invented a plastic drag chain made by injection molding in 1967. It successfully pioneered more products: lightweight drag chains, 3D drag chains, and seamless drag chains.
As of 2007, there were more than seven global manufacturers, including FESMA, Murr Plastik, igus, KABELSCHLEPP, Metreel, M Buttkereit, Gortrac and Cavotec. In 2010, Tsubaki merged with Kabelschlepp, which is now Tsubaki Kabelschlepp.
Drag chains can be classified into steel drag chains and plastic drag chains. Steel drag chains are composed of steel and aluminum and can be customized. Engineering plastic drag chains are also known as plastic drag chains or tank chains. Drag chains are classified into three types based on different application environments and requirements: bridge-type drag chains, fully enclosed drag chains, and semi-enclosed drag chains. Rectangular frame metal hoses, protective sleeves, corrugated tubes and metal hoses can also be included in drag chain protection and portable power supply products.
Drag chains are applied in reciprocating motion scenarios and can play a role in pulling and maintaining the embedded cables, oil pipes, air pipes, water pipes, etc. Drag chains have been widely used in fields such as CNC lathes, electronic products, printing machinery, mechanical hands, loading and unloading machinery, plastic machinery, lifting machinery, woodworking equipment, the automotive industry, industrial chain vehicles, metal material processing equipment, CNC machine tools, forging and pressing machinery, and port facilities.
I. What is a drag chain cable?
When we are doing foundation construction or during the production and manufacturing process, many cables are involved. However, sometimes we don't know how to move the cables without damage. In such cases, drag chain cables come into being.
The drag chain cable is placed in the drag chain to prevent the cable from entanglement, wear or disorderly hanging, thus forming self-protection. Now let's introduce what drag chain cables are? Specifications and models of drag chain cables, as well as national industry standards and applications of drag chain cables.
The cable moves back and forth along with the drag chain. This highly flexible special cable that can move back and forth with the drag chain without being easily damaged is called a drag chain cable. Drag chain cables are mainly used in situations where they need to be repeatedly moved and bent. Compared with general cables, they have the following advantages: high flexibility, oil resistance, shallow water resistance and moisture resistance, resistance to solar radiation, excellent aging resistance, temperature resistance, wear resistance, and the ability to bear heavy mechanical external forces. The cable has a faster acceleration and stronger bending resistance than ordinary flexible cables. It's inevitable.
