Description

The MEGABRIK, which was designed in 1985, is conceived as a machine consisting of several components that can be assembled in different combinations, according to the requirements of the user. It is, therefore, available as an assembly kit, designed to be put together by a "low-technology" artisan, as well as in a fully assembled, ready-to-use version.

The kit version includes:

· a semi-automatic or automatic hydraulic device, 100 x 80 x 30 cm, called PROHA 15 s (Process Hydraulique Automatique) weighing 85 kg and consisting of a pump, a 100 1 hydraulic fluid tank and command panel;

· a compression device, 70 x 70 x 70 cm, called COMPAC 30 tonnes, weighing 320 kg and comprising a mould, moveable hopper with 4 hydraulic jacks and 2 vertical stroke hydraulic jacks for compression;

· and a set of blue prints for assembly.

The ready-to-use version is fixed on a self-carrying chassis with 2 pneumatic wheels, in accordance with road transport standards. The machine is powered either by an electric motor or a 15 hp diesel engine, and can be equipped with a 200 I capacity planetary mixer, which is assembled on two lateral pivoting shafts, which are moved by a hydraulic jack.

Operating the MEGABRIK

The earth, stabilizer and water are fed manually into the mixer, which blends the contents in 200 s cycles. It is then lifted up automatically by the lateral pivoting shafts to fill the hopper.

The hopper incorporates a vibrating system (exclusive) for constant volume filling of the mould. The top cover of the mould is also attached to the hopper and moves back and forth with each change of the hopper's position, as shown in the diagram.

The filling, compression and turning out is done semi-automatically by means of a 7- position manually operated lever, or automatically by means of a pre-programmed device with a hydraulic by-pass. The theoretical duration of one production cycle is 20 seconds for semiautomatic operation and 15 seconds for automatic production.
