Zuber Maschinenbau – A Division of Marcrist
Zuber Maschinenbau is a brand of Marcrist Diamantwerkzeuge Vertriebsgesellschaft mbH based in Waldshut-Tiengen in the Southern Black Forest. The product range includes hydraulic stone splitters (HS33Z, HS44Z, HSN20), stone cutting machines and slab saws (PS1050NJ) for landscaping, paving and natural stone construction, stonemasonry and paving contractors, as well as facade and tile work. The machines operate without mains power or hydraulically and are characterized by robust construction site design, low-maintenance technology and case-hardened splitting blades made of special steel. Manufacturing is carried out under the 'Made in Germany' or 'Made in the Southern Black Forest' quality seal. After its founding by tool and apparatus maker Karl Alfred Zuber after the Second World War, the family company achieved its worldwide breakthrough with the hydraulic stone splitter; in 2018, Horst Zuber transferred parts of the company to the diamond tool manufacturer Marcrist. Sales are handled through the Waldshut-Tiengen location and the partner online shops mytoolexpert.de and mytoolexpert.ch.
