Description

The Geo 50 is produced in collaboration with Ste SOUEN, Centre de Terre, Lavalette, F-31590 Verfeil, where Joseph Colzani, ARCHECO, developed the machine in 1984.

The portable block press is designed to produce soil blocks with the lever action only on one side. The downward movement of the lever pushes the vertical stroke piston upwards and simultaneously pulls the mould cover downward by means of a cam, thus achieving double compaction and consequently higher density blocks.

It is advantageous to mount the machine on a strong wooden base board or two strong beams to provide rigid support.

Operating the Geo 50

Generally, two people are sufficient to operate the machine, and three or four people are required for excavation, transportation and preparation of the soil.

The mould is conveniently filled from the side opposite the lever arm. The cover, which is hooked to the lever arm, is pushed to vertical position and unhooked, allowing the lever arm to be pulled back to horizontal position, by which the block is fully compacted. Back to vertical position, the lever arm is hooked to the cover, which is pulled back, ejecting the compressed block, which is removed for drying.
