The straightforward answer to whether flat (N)TSFLCGEWÖU cables are superior to round cables for overhead crane festoon systems is: yes, absolutely—flat cables are genuinely better for festoon service in nearly every measurable way. The flat architecture delivers real engineering advantages in space efficiency, thermal performance, and mechanical reliability that address fundamental limitations of round cables in repetitive reeling applications. However, there is a critical and commonly overlooked distinction that separates successful flat cable installations from catastrophic failures: the extremely heavy 4×185 flat cable cannot be installed on standard C-track systems—it absolutely requires upgrade to heavy-duty I-beam or H-beam track systems rated for the cable’s mass and tension. Many engineers and crane manufacturers have attempted the false economy of installing maximum-capacity flat cables on minimum-weight track systems, resulting in track deformation, trolley wheel failure, and serious safety hazards. Understanding why flat cables are superior and understanding why proper system specification is essential for safe operation are two sides of the same engineering decision.
