ABSTRACT OF THE DISCLOSURE For casting large concrete articles, a wheel-mounted main frame supports a mould assembly which can be rotated about a horizontal axis, and also raised and lowered. This assembly has two main mould sections oppositely arranged so that when one faces upwards the other faces downwards. A removable mould section fitted to each main mould section forms a complete mould capable, when uppermost, of receiving concrete to be cast. The mould assembly may then be inverted and lowered to a support, and the removable mould section disconnected to serve as a pallet for the cast article. The mould assembly may be raised, concrete may be cast in the other mould, which is uppermost, and the main frame may be moved clear of the deposited cast article. -1-
