TROWIS GmbH
TROWIS GmbH develops and manufactures high-performance fiber ropes for hoisting and conveying technology, offering innovative, lightweight alternatives to steel wire ropes for cranes, elevators, and industrial lifting applications.
About
TROWIS GmbH, based in Chemnitz, Germany, is a technology-driven manufacturer and developer of high-performance synthetic fiber ropes. Specializing in innovative rope solutions for cranes, elevators, and industrial applications, the company's core expertise lies in producing ropes that are lighter, more durable, and offer higher load capacities than conventional steel wire ropes. TROWIS ropes integrate advanced features such as redundant, self-monitoring fiber composite structures and sensor elements for state monitoring, enabling maximum operational safety and extended service life. The company's proprietary rope finishing processes ensure longevity, low initial elongation, and minimal maintenance. As a spin-off from TU Chemnitz and Hochschule Mittweida, TROWIS continues to advance the state of fiber rope technology through in-house research, strong industry partnerships, and sustainable production practices.
