For the most diverse and complex applications in the field of construction machinery, e.g. tunnel excavation machines, hoisting gear and transport equipment, RINGFEDER® offers solutions implementing maximum power densities even under extreme conditions. Whether couplings for huge torques and speeds or locking devices and damping elements for extreme dimensions and loads have to be implemented – in larger-scale and smaller-scale plants from the construction machinery industry, RINGFEDER® products ensure maximum productivity, durability and safety.
An optimum road surface is the fundamental prerequisite to ensure safe, comfortable and economic driving. In order to implement this, the road construction machine used must achieve a correspondingly high-quality output. In the case of asphalt pavers, RINGFEDER® supports this by the use of compact and robust friction springs, which are specially designed in collaboration with one of the world’s leading manufacturer of road construction machines: By means of friction springs, installed to ensure impact protection, an excellent image of quality is put on the road – even if ambient conditions are extremely rough as is the case with heavy pollution, high air humidity or extreme differences in temperature.


Whether we’re talking about tunnel construction facilities, cranes, shredder facilities, excavator and transport vehicles or similar devices – RINGFEDER® offers the perfect efficient solution for building and construction machinery of any type, design and size. Highly elastic coupling systems for diesel units or conventional shaft couplings for hub drives are typical customer applications in this sector. Our torsionally stiff flange couplings as well as our elastic and highly elastic flange couplings, our range of locking assemblies and shrink discs as well as our friction springs are also perfectly suited for the use in this segment. Always specially tailored to meet the specific requirements of the customer and the application.

The ideal selection depends entirely on power ratings, operating speeds, and alignment tolerances. For standard setups, elastomer jaw couplings are favored for low-maintenance vibration damping, while high-performance disc couplings or heavy-duty gear couplings are commonly deployed in massive industrial pump networks.
Vertical pump applications require specialized vertical motor-to-pump couplings built to handle distinct axial loading and structural configurations. These engineered systems are widely implemented across water treatment plants, pumping stations, and regional lift irrigation projects.
Steel manufacturing environments—including rolling mills, heavy crushers, conveyors, and auxiliary drives—require extreme durability. High-torque gear couplings, torsionally rigid disc couplings, and metallic grid couplings are heavily utilized to manage these rigorous load cycles.
High-torque gear couplings are optimal for heavy processing machinery like cement plants, mining equipment, conveyors, and crushers. For power generation systems, cogeneration units, and steam plants, torsionally flexible jaw couplings and disc couplings are heavily relied upon to offset shaft misalignments and protect rotating assemblies.
Maintenance engineers should regularly monitor machinery for signs of deterioration. The most common indicators of field wear include excessive system vibration, unusual operational noise, lubricant leakage on grease-dependent models, elastomer deterioration on flexible spiders, and a noticeable increase in running temperatures.
To achieve maximum service life and prevent premature breakdown, industrial facilities must strictly maintain precise shaft alignment, adhere to recommended lubrication schedules on gear models, safeguard the system against overload spikes, run regular physical inspections, and proactively replace components during planned maintenance shutdowns.
Yes. For legacy equipment or specific field constraints, customized coupling solutions can be custom-engineered to meet precise torque demands, speed constraints, and shaft parameters. Full application engineering assistance, technical consultation, and comprehensive documentation like GA drawings and data sheets are available for factory upgrades.
