Chinese Name: Towing Chain mbth: Cable Towing Chain Invention Time: 1953 Shape: Similar to the history of tank chain, the overview, structure, basic parameters, main classification, materials, forms, assembly forms, towing chain characteristics, market model, application scope and history of plastic towing chain were invented by German professor Gilbert Waninger in 1953. 1954 Waldrich, the boss of KABELSCHLEPP, which was founded in Siegen, Germany, thinks that the towing chain is a brand-new market, which can create huge demand and start to promote the first towing chain to the market. A concept more than 60 years ago has created a huge market now. Now the first original steel towing chain model has developed into a * * * shaped steel-plastic towing chain, which is widely used in many fields. KABELSCHLEPP Gaborone Company invented the first plastic towing chain molded by injection molding in 1967, and successfully created more firsts: portable towing chain, 3D towing chain and wireless towing chain. Up to 2007, there are more than seven manufacturers in the world, including FESMA, MURRPLASTIK, Iguisigus, Toona KABELSCHLEPP, Metreel, M Buttkereit, Gortrac and Cavotec. 20 10, Toona merged with Gabrielle Company, now Toona Kabelschlepp Company. Towing chains are divided into steel towing chains and plastic towing chains. The steel towing chain is made of steel and aluminum and can be customized. Plastic towing chain is also called engineering plastic towing chain and tank chain. Towing chains can be divided into three types according to the use environment and requirements: bridge towing chains, fully enclosed towing chains and semi-closed towing chains. Towing chain protection and mobile power products can also include rectangular metal hoses, protective sleeves, corrugated pipes and metal hoses. The towing chain sleeve is used for reciprocating motion, which can play a traction and protection role for the built-in cables, oil pipes, gas pipes and water pipes. Towing chain has been widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine manipulator, handling machinery, plastic machinery, lifting equipment, woodworking machinery, automobile industry, industrial vehicles, metalworking machinery, machine tools, casting machinery, port equipment and other industries. The structure of plastic towing chain looks like a tank chain, which is composed of many unit links, and the links can rotate freely. The inner height, outer height and pitch of the same series of towing chains are the same, and the inner width and bending radius r of towing chains can be selected differently. The unit link consists of left and right link plates and upper and lower cover plates. Each section of the towing chain can be opened, which is convenient to assemble and disassemble without threading. After the cover plate is opened, cables, oil pipes, gas pipes and water pipes can be put into the towing chain. Each part of the traction chain can be designed to be openable for easy installation and maintenance. Low noise during exercise, wear resistance and high speed movement. In addition, you can provide a separator to separate spaces in the chain as needed. Basic parameter material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant and stable performance at high and low temperatures, can be used outdoors. Resistance: oil resistance, salt resistance, and certain acid and alkali resistance. Running speed and acceleration depend on running conditions. Because of its light weight and smooth operation, the Gabrielle towing chain can run at a long distance and high speed, and can accelerate and stop suddenly. The main classification materials can be divided into: steel towing chain, steel-aluminum towing chain, plastic towing chain, stainless steel towing chain, nylon towing chain and so on. Forms can be divided into: bridge towing chain, multi-section bridge towing chain, closed towing chain, silent towing chain, open towing chain, S-type towing chain, universal towing chain, tank chain, threading towing chain and so on. According to the requirements of the use environment: oil-proof, waterproof, garbage pollution-proof, acid and alkali resistance, high temperature resistance, friction resistance, extension, load-bearing, no noise, hidden cables, etc. Assembly form: bridge towing chain, fully enclosed towing chain and semi-closed towing chain. Towing chain has high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardant, stable high and low temperature performance, and can be used outdoors. Resistance: oil resistance, salt resistance, and certain acid and alkali resistance. Running speed and acceleration (the specific speed and acceleration depend on the running situation). Long service life. The market models of steel-aluminum towing chain can be divided into TL type, TGA type and TGB type. Plastic towing chains can be divided into heavy and light. Scope of application: 1 Suitable for reciprocating occasions, it can play a traction and protection role for built-in cables, oil pipes, gas pipes and water pipes. 2. Each section of the towing chain can be opened, which is convenient for installation and maintenance. Low noise during exercise, wear resistance and high speed movement. 3. Towing chain has been widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, robots, lifting and transportation equipment, automated warehouses, etc.
