The Cinva Ram was developed in 1952 by Raul Ramirez of the Inter-American housing center in Columbia. It was very popular in Columbia and neighbor developing countries, due to an effective low cost design.
With this machine, 2 workers, 1 loading the machine and the other working the press, can produce roughly 2 bricks per minute
- note, these plans are so far only on paper, the ram head might be to short, in a few days the prototype will be complete and ready for testing. If it doesn't work,it will only need another layer of steel welded to the ram head to give it more compression (it might only work with sandier soil that doesn't compress as much). It should work fine as is.
