In this episode of Let’s Talk Elevators, host Morgan Jones is joined by two globally respected industry experts, Torsten Fuka of FUKA and Nicola Imbimbo of Prysmian, for a deep technical conversation on one of the most critical and misunderstood relationships in elevator systems, the interaction between suspension means and traction sheaves. Torsten and Nicola bring decades of hands-on experience spanning manufacturing, maintenance, application engineering, and global code development. Together, they explore how ropes, belts, and sheaves must be engineered and applied as a complete system, not as isolated components. From known failure points in the field to overlooked installation practices, this episode breaks down why performance issues often stem from configuration, alignment, tensioning, and maintenance habits rather than product defects. The discussion covers how modern demands for smaller sheaves, higher performance, and longer service life create real engineering tradeoffs. Nicola explains why lifetime should be measured in trips rather than years, how reverse bending accelerates wear, and why configuration data is essential when evaluating performance expectations. Torsten shares insights from decades of endurance testing and explains how groove design, surface hardness, and manufacturing processes directly affect long-term reliability. The episode also dives into coated suspension means and belts, highlighting why these systems require a completely different mindset than traditional wire ropes. Topics include surface roughness, cleanliness requirements, contamination risks, and why interchangeability is not guaranteed across manufacturers. Both guests emphasize the importance of tested combinations, proper training, and field discipline to avoid premature failures. Listeners will also gain insight into common field issues such as improper rope uncoiling, unequal tensioning, misaligned sheaves, and lubrication mistakes. Nicola outlines how correct lubrication practices can extend life when done properly, while incorrect products can cause immediate problems. Torsten reinforces the role suppliers play in education, testing, and collaborative troubleshooting. The conversation closes with forward-looking perspectives on lightweight systems, IoT monitoring, vibration analysis, and how data-driven maintenance will shape the future of elevator performance. This episode is essential listening for technicians, engineers, consultants, manufacturers, and anyone responsible for designing, installing, or maintaining elevator systems who wants to reduce failures, extend component life, and improve ride quality through better engineering decisions.
