The invention relates to lift installations, to counterweights (1; 10) and to methods for producing same. For this purpose, a mould (2) is provided and an envelope (5) is provided, and a filling material is filled into the envelope (5). Moulding and/or compaction of the filling material takes place under negative pressure at least within the envelope (5), wherein the envelope (5) is situated within the mould, with the result that the filling material assumes a shape corresponding to the mould (2).
