PRECAST CONCRETE ELEMENTS144 CPI %u2013 Concrete Plant International %u2013 1 | 2026 www.cpi-worldwide.comThe mould incorporates an active and a passive stressing heads, located at both ends of a central core. Together with the side panels and base plates, these elements define the final geometry of the pieces to be manufactured.For its proper operation, Moldtech supplied two hydraulic power units:one for opening and closing the side panels and for the vertical movement of the bottoms, and another for the hydraulic detensioning process of the strands.During operation, the mould can be complemented by various auxiliary systems %u2014 a hydraulic detensioning unit, a heating system for concrete curing, stressing accessories compatible with the maximum capacity of 600 tonnes, and a hydraulic unit for synchronized movement of the side panels %u2014 all designed to optimise production and ensure the highest quality of the final product.The TT slab mould features variable geometry, enabling rib heights to be adjusted from 400 mm to 800 mm and slab widths to be configured from 1.42 m to 2.49 m.The mould incorporates hydraulically adjustable and interchangeable base plates, allowing quick and precise changes to the slab section according to project requirements.In addition, the mould is preinstalled with a heating system comprising covers and pipes for the circulation of a thermal fluid, enabling accelerated curing of the concrete and reducing production cycle times.The maximum stressing capacity of the mould reaches 600 tonnes, distributed among four detensioning cylinders located in the active head: two 200 tonnes cylinders in the lower mask and two 50 tonnes cylinders in the upper mask.The self-reacting TT mould integrates both the stressing heads and the main structure, simplifying installation, dismantling and potential relocation to other production sites.Hydraulic column mould L = 34 m: manufacture of long structural elementsThe hydraulic column mould L = 34 m is designed for the production of reinforced concrete columns up to 34 meters in length, with adjustable cross-sections between 400 mm and 900 mm.Its hydraulic system, composed of synchronized cylinders, allows safe and efficient operation for the opening, closing and lifting of the bottoms, thereby optimizing production times.The equipment consists of two side panels (34 m each) and a base (800 mm wide), which, when assembled, define the final geometry of the column.Stressing heads - 600 tonsHydraulic mould for columnsPrecast concrete TT slab Precast column
