Structural products of hardening materials based on mineral binders, e.g. concrete, are formed in moulds movable on guide rails wherein the products are moulded on a lower guide rail, heated during raising to an upper guide rail cooled while on the upper guide rail and stripped from the mould after lowering to the lower guide rail. The moulds are raised from the lower to the upper guide rail in a stack which is fed from the bottom upwards. As shown, the mould 4 mounted on wheels is cleansed at II, filled at stations III, IV, V and VI, checked at VII and passed to one of the devices 8, 8a, 8b, 8c, 8d or 8e for assembly into stacks. Each device 8 comprises fixed frames 30 and movable frames 19 which can be raised in synchronism by hydraulic rams 20. The mould is stopped on rail section 27 and is raised by this section to a first position where it is held by pivoted latches, and steam is passed around the mould to cure the concrete. The mould is raised one step when each new mould is added to the stack and finally reaches the top rail 2 along which it is moved, through cooling devices to the lowering device 7. The lowering device 7 comprises a fixed frame 14, a winch 15 and a platform 16 mounted on two horizontal bars 17. Platform 16 carrying a mould is lowered to the level of the lower guide rail and the platform and mould is tilted about a horizontal axis along the line of the machine so that the moulding can be removed.
