About Martin Brunner GmbH
Martin Brunner GmbH is an engineering office with its own in-house workshop in Lauterbrunnen in the Bernese Oberland. Its core competencies include 2D and 3D design, strength and FEM calculations, approvals under BAV and EN standards, and the production of functional samples, prototypes, ready-to-install components and turnkey machines and systems. Manufacturing takes place in the company's own workshop with an indoor crane, predominantly in steel and stainless steel, including welding to EN 15085-2. Customers include mountain railways and railway companies such as Jungfraubahn, Berner Oberland-Bahnen and BLS, as well as manufacturers from mechanical engineering, plant construction, cableway and vehicle construction. In addition, the company offers external welding supervision (vSAP), WPS creation and visual inspections. With the Chäsbrätelofen product, the company is also active in the gastronomy supplies sector.
