We´ve been building machinery and accessories for the manufacture of prestressed concrete for 60 years in close cooperation with users from all over the world. In 1959 Paul delivered the first single-wire stressing jack with the then revolutionary two-button operation, and, with this development, laid the foundation stone of a successful future.
Expanded and extended, step by step over the course of years, the available lines today cover a broad range of machines and accessories for the different processes in the production of prestressed concrete. We are in a position to supply you with all machinery and accessories required for the cutting, stressing and anchoring of prestressing steel. The wide choice of stressing jacks, pump units and detensioning cylinders for various prestressing forces is supplemented by useful devices such as steel cutters or strand pushing machines which greatly ease the daily concrete working jobs.
