The supplied moulds are identical in design but different in overall dimensions and area of the hatch (middle or offset location, which is governed by ease of maintenance).
Each mould consists of a pan, which is a steel integral bearing element equipped with a load gripper, a fixed side installed on the pan floor and closed sides linked to the fixed side using hinges (movable joint) and to each other with the help of a latch (separable joint). The internal former is installed on the pan and the cowl safeguards the pan against concrete mixture ingress into it.
During demoulding, the cowl is removed and the clamps that fix the internal former are screwed off. By unscrewing the nut, the internal former is first shifted and then removed from the concrete product using slings attached to special lifting lugs. The latches that link the sides together are released by unscrewing upon which the sides are opened and the product is removed from the mould. If all specified filling procedures are followed, the finished lid is perfectly plane and ready for use.
The lid being seemingly a minor component at the level of terminology is, when combined with the pipe, the practically important and inherent element of the integral structure, which is capable of performing the assigned duties.
