Description[edit | edit source]

The Multibloc 5, 8, 12 mobile blockmaking machines are compact low level machines. They are easy to operate by one man, producing blocks on the floor, thus eliminating pallets and reducing breakage of blocks, ensuring high production efficiency. The machines have few moving parts and are easily maintained. Mouldbox and tampers are quickly interchangeable, enabling a wide range of different blocks to be produced.

The machines can be operated by electric motor, diesel or petrol.. Electrically the supply requirement would be either 380 volts, 3 phase 50 cycle or 220 volt, I phase 50 cycle. Alternative supplies require special consideration. Traction is offered as an option on electric models if required

Operating the Multibloc machines[edit | edit source]

Multibloc machines are designed so that they can be teamed up with feeding and handling machines to give a smooth totally integrated operation that saves time and money. For the Multibloc 5 it is best to use a Feed Barrow and Hand Lift Truck, while the Multibloc 8 and 12 are best combined with the Power Feed Truck and Hand Lift Truck.

The mixed concrete is tipped into the feed tray using a hand barrow or power feed truck.

Cb P05.GIF


The concrete is raked into the mouldbox area until it is 4-5 cm (1.5 - 2 in) above the level of the mould.

Cb P06.GIF


The mouldbox is vibrated by pushing down the foot switch for a few seconds. Pre-vibration time varies according to block disign and type of materials used. The hand rake is used to ensure even distribution in the mouldbox ,raking surplus material onto the feed tray.

Cb P07.GIF


The tamper is pulled over the mould, with the rake and the catch released, dropping the tamper onto the concrete in the mouldbox. Vibration is repeated until the tamper comes down to the height stop tubes.

To eject the blocks, the handle is pulled down until the tamper catch engages, lifting the mould clear of the blocks. The machine is then pulled forward the required distance and the operation repeated for the next cycle of blocks.

Other Multibloc Machinery for Concrete Blockmaking[edit | edit source]

Multibloc looks back on 40 years of experience in the production of machines for concrete blockmaking, which are being used in more than 100 countries throughout the world. In addition to the three machines described in this leaflet, Multibloc offers two larger machines: Multibloc 16 and Multibloc 36.

The Multibloc 1 6 is a hydraulically operated block maker, which lays the building blocks on the floor. The machine can be electrically, diesel or petrol driven, and controlled by an operator sitting on an adjustable pivoted seat. The concrete is delivered direct to a sliding feed box, which fills the mouldbox without any physical effort. Since there is no operator fatigue, block production speed i consistently high throughout the day.

The Multibloc 36 is a larger model of the '16' with added facility for increased output A large hopper with hydraulically operate' door reduces the dependence on the feed truck and improves production speed.

A special Multibloc Truck is available for the efficient feeding of concrete to the ma chines and removing of cured products.

Multibloc also produces the BREPAK Bloc Press for making compressed soil block (for details see GATE Product Information: Soil Block Presses).
