The Multivibe is a multi-purpose, detachable vibrating machine for the small-scale production of concrete blocks and a large variety of other concrete building components. It is a portable machine which can be operated from any angle and can be clamped to a wide variety of forming tools, such as concrete block moulds, rooftile screeding machines, table surfaces or to the shuttering for'in situ' concrete work.

The Multivibe can be powered from any 12 volt DC source, car battery, or from the mains through a transformer rectifier, and is available in two capacities: 4 amp and 6 amp.

For concrete hollow block production, three standard sizes of mould are available to make blocks of different widths (10,15 and 20 cm, or 4, 6 and 8 inches), the length and height being constant (39 x 19 cm, or 15 x 7.5 inches). In addition, three standard moulds are available for making curved blocks to produce water tanks of 2 m, 3 m and 4 m diameters.

All components of the blockmaking plants are fully portable and can thus be used on any appropriate site with a flat surface large enough to place the required number of blocks for curing. With appropriate accessory packs, it is also possible to switch between products (such as floor, wall or roof tiles, posts, lintels, pipes, window frames, latrine slabs and many others) at very short notice.

Other building components produced with the Multivibe concrete technology.
