Hydraulic tensioner

Among the complementary equipment that Resimart offers to concrete pre-tensioning manufacturers, there is a wide range of systems for tensioning wires or strands as well as systems for progressive de-tensioning once the concrete has set. In addition to the machines required for the manufacturing of the parts pre-stressed concrete as the casting machine or extruder, Resimart, machinery manufacturer with over 40 years of experience, also includes in its catalog a multitude of complementary equipment to offer a complete service to its customers. In this case, we are talking about a wide range of systems for tensioning and de-tensioning wires and strands, a fundamental part in precast concrete, whether vibro-compression or extrusion technology is used. It is a complete system of tracks for guiding, tensioning and subsequent progressive de-tensioning of the wires of prestressed concrete precast. Hydraulic tensioning systems For thetensioning of wires or strands we have hydraulic tensioning systems suitable to the specific needs of each installation. This system can tension each of the wires (individually or in pairs) until the appropriate tension is reached. De-tensioning head Active De-tensioning anchor head The active or de-tensioning anchor head is prepared to maintain the tension of wires or strands of any diameter and is designed in such a way that it allows, by means of a hydraulic device, to reduce the tension of the assembly progressively. In this way, any problems in the newly manufactured product are avoided.
