URSUS® MT KN PLUS

The URSUS® MT KN PLUS represents a paradigm shift in high-performance reeling cable engineering. Designed for applications operating at 240 metres per minute—more than 3× faster than standard TBM or mining hoist cables—this cable combines extreme mechanical durability with unprecedented lightweight performance, enabled by Kevlar®-reinforced core construction. Applications requiring ultra-high-speed reeling (deep-sea drilling riser deployment, offshore wind turbine installation vessels, ultra-fast tunnelling machines, and extreme industrial winches) have long sacrificed either speed capability or mechanical reliability. Conventional cables break under the torsional and tensile stresses of 240 m/min operation. The URSUS MT KN PLUS eliminates this compromise: it delivers double the tensile strength of standard cables while reducing overall weight and diameter, enabling faster deployment cycles, larger cable payloads per reel, and dramatically improved operational efficiency.

Tunnel boring machines (TBMs) represent some of the most electrically demanding and mechanically extreme operating environments on Earth. A typical hard-rock or mixed-ground TBM operates in a pressurized, confined underground chamber where hundreds of kilograms of electrical cable snake around reeling drums, hydraulic power systems, and high-frequency motor drives operating at medium voltage (6/10 kV). The electrical environment is noisy with harmonic distortion from variable-frequency drives; the mechanical environment is brutal, with cables flexing repeatedly as they wind and unwind from rotating drums at speeds up to 20 metres per minute.
