The machine for manufacturing moulded bodies made of vibrated concrete consists of a portal-shaped machine stand with a lifting framework, which can be moved up and down and on which at least one moulding mantle and one mould table are suspended, which table receives in an opening the upper end of each moulding mantle and ends approximately flush therewith, of at least one moulding core which, in the production position, engages coaxially in the moulding mantle, delimits with the latter as well as an upper and a lower closing part a moulding space, is supported in a stationary manner in the pit via pivoting bearings and is provided with a vibrating drive, of a lifting table which, by means of a drive, can be moved out of a lower end position sunk into a pit into an upper end position which ends approximately flush with the upper pit edge and the surrounding work floor, and has, for each moulding core and surrounding the same at a distance, a passage opening, and of a device for supporting the upper closing part in the upper end region of the moulding mantle during the production operation. The lower closing part is in this case, in the production position of the moulding device, connected detachably to the moulding mantle, and, by raising the moulding mantle, the finished moulded body can be removed from the moulding core and transferred into a hanging position slightly above the work floor. Furthermore, the machine stand can be moved on rails above the work floor by means of a drive between its production position and a set-down position ... Original abstract incomplete.
