Our product range for bridge construction includes a wide selection of stressing jacks, hydraulic units, pushing machines, anchor grips and handling equipment. Due to the decades of experience we offer rugged and long-lived machines for heavy-duty use on construction sites. Our machines are in use all over the world for stressing bridges, stay cables, but also for stressing LNG tanks under various climatic conditions.
Engineers have already dealt with stay cable technology for spanning rivers or canyons long before the invention of prestressed concrete. Nowadays, stay cables are prestressed and are thus considerably contributing to the span and stability of the structure.
Stay cables are either completely lifted/pulled from the bridge platform to the pylon or individually inserted and locked by means of wedges. Afterwards, depending on the method, all the cables are stressed using multi-stressing jacks or each cable is stressed immediately after insertion using single-strand stressing jacks. Paul offers solutions for this special application in bridge decks or on high pylons.
The efficiency of wind power plants increases with the hub height. Particularly in the onshore sector, the required wind conditions with low turbulences and constant/high speed can only be found in higher wind layers. The hub height which nowadays often is (considerably) over 150 m also results in special demands on the statics of the wind power tower. Due to the big force acting on the tip of the tower via the rotor blades, the tower wants to bend. To counteract, the concrete towers are reinforced by means of tendons. Paul supplies equipment both for concrete towers made of prefabricated parts and for the concrete bases of hybrid towers.
Another major field of application for machines and equipment from Paul is geotechnics. Geotechnics often isn’t noticed in everyday life; however, it isn’t only used in mountainous regions for slope stabilization, for instance, but in many cases also on construction sites and in building pits. A great variety of equipment is available both for temporary removable anchors and for permanent anchors. We also supply the appropriate stressing jacks for bar anchors. We see our challenge in your special requirement. Paul supplied for example two stressing jacks with 1500 kN and 22000 kN, each with 1000 mm stroke, for 95 m long ground anchors with 61, i.e. 91 strands, including an official calibration certificate.

Paul produces manual, semiautomatic or fully automatic anchor manufacturing equipment for cost-effective and time-saving preparation of tendons for use on the construction site for bridges, stay cables, geotechnical engineering or wind power towers. We are complying with your requirements and the local conditions.
