Ever since the industrial revolution, railways have formed the backbone of industrial societies with the development of the two going hand-in-hand. In that time, we’ve progressed from steam-powered locomotives to high-speed trains that travel beyond 300 km/h (175 miles/hour). But the principle remains the same: trains need to be reliable and they need to be on time. Bolt loosening anywhere on railway infrastructure and rolling stock can be costly, and even fatal if a train is in motion.
With hundreds of thousands of kilometers of tracks covering the earth’s surface, along with numerous types of switches, checking and tightening bolted joints is time consuming and tedious work. It is critical to ensure that your chosen bolt securing product will hold despite the elements.
As trains and railway networks become more advanced, so do the demands on rail lines and train components. When a train is travelling at over 300 km/h, the whole carriage is rattled with constant vibration and strain. Bolt security is essential for safety and Nord-Lock products are used in production as well as in maintenance. Common applications include e.g. switches, noise absorbing walls but also bogies (railroad trucks), couplers and brake systems. Nord-Lock products are also used for securing underfloor equipment.
