ntt GmbH is a German small business. Its focus is the development and manufacture of exceptional custom designs in the fields of safety, access, and rope technology, as well as the construction of special ropeway systems.

Pioneering work: the birthplace of TOPPAS® As the inventor of the TOPPAS® auto belay, we have revolutionized the world of climbing and fall protection. What began as an engineering achievement in our company is now a globally valued standard for safe, partnerless climbing. All “Made in Germany”

The company was founded in 1978 by Willi Neuhaus and expanded in 1991 to become ntt neuhaus trans tech GmbH.
In 1996, TOPPAS was born. Auto belays, or climbing machines as they are now found in almost every climbing gym, were true rarities back then.
From the very beginning, ntt has focused on excellent service and product durability. We continue to carry this standard in our hearts.
The core team currently covers various business areas, enabling us to support our customers optimally at every step of the planning process.

We rely on quality workmanship, reliable service, and high production standards. For larger custom designs, we work with specialists and expert companies in Germany and abroad, with whom we are in constant exchange.

ntt neuhaus trans tech GmbH brings together highly qualified employees from the fields of engineering, sales, design engineering, and design under one roof.
