In the sector of rail freight, the relentless pursuit of safety and reliability remains paramount, especially when tasked with transporting hefty cargo across extensive distances.
Amidst these challenges, splice joint bars emerge as a critical component, susceptible to loosening in the face of environmentally extreme conditions. J. LANFRANCO Company introduces a solution with its THU self-locking nuts, which redefine the priority of rail safety.
Conventional fastening techniques, often comprising multifarious components, tend to falter under the exacting circumstances. In stark contrast, J. LANFRANCO Company’s THU self-locking nuts emerge as a superior alternative. With their full-height design, featuring twin slots positioned on the same plane, these nuts exhibit remarkable resilience to high-frequency vibrations, imposing loads and the harshest of temperature extremes.
The efficacy of THU nuts has been proven, even in the face of extreme conditions such as temperatures as low as -14°C.
J. LANFRANCO’s THU self-locking nuts offer immediate advantages for rail freight enterprises. By preventing loosening and its consequences, THU nuts usher in an era of reduced maintenance expenditure and diminished downtime, stemming from the elimination of fastener-related costs. Unlike traditional methods that necessitate tightening on a daily or monthly basis, the self-locking capability of THU nuts obviates the need for such frequent interventions, saving precious time and curtailing labour expenses. Furthermore, the compatibility of THU nuts with impact wrenches improves the fastening process.
The success of THU nuts for fastening rail joint bars has proven itself within the extensive 1,000km of the New York transit network, the largest in North America, encompassing intercity trains and subterranean subway systems. With over 8 million passengers relying on this network’s daily operation, the integration of THU nuts assures the safety and stability of joint bars, thereby a more efficient and secure transportation system.
