DYWIDAG CFRP Hollow Jacks
The lightest stress jacks for quick and easy handling.
Carbon Fiber Reinforced Hollow-piston (CFRP) Cylinders are a lightweight and versatile jack, typically used for the quick tensioning and testing of bar and strand anchors. An ideal alternative to conventional steel hollow-piston cylinders, they guarantee easy, quick and efficient positioning and handling. In most cases, lifting tools are unnecessary for their transportation and assembly.
The hydraulic return allows for a quick retraction of the cylinder, with the new, economical, round design of 150bar in the return enabling even quicker retraction than before. The corrosion-resistant material, impact-resistant aramide cover, and integrated overflow and pressure control valve make this a robust, damage-resistant product that can withstand the rigors of site use.
CFRP Hollow-piston Cylinders can be used for a wide range of tensioning, maintenance, and lifting applications through the addition of a large range of accessories. We offer a number of options, including the rental of jacks and accessories, as well as repair and calibration services.
