Jesson Lightning II MK 2 / Lightning IV brick/block makers
Description
The Lightning II MK2 and Lightning IV Brick/ Block Makers are all-steel constructions, which function as "egg-laying" machines capable of making a variety of concrete bricks and blocks at a high output rate. Several interchangeable moulds are available and special moulds can be made to order.
The Lightning II MK 2 is fully manual, but can be fitted with electric vibration, if required, while the Lightning IV is electrically operated, but can also be supplied with a petrol engine. A unique feature of the Lightning II MK 2 is a mechanical size assessment stop, which prevents odd-sized products being made.
Operating the Lightning II/IV Machines
For brick or block production a smooth, level 10 cm thick concrete slab is needed, large enough to accommodate 1.5 days output, that is about 300 m² for the Lightning II MK 2 and about 750 m² for the Lightning IV.
Both machines have a concrete bin, from which the moulds are filled. The concrete is tamped up to a predetermined height and, leaving the compactor down, the mould is lifted off the bricks/ blocks and the machine rolled back to the next drop point, where the mould is lowered, the compactor raised and the cycle repeated. After 24-36 hours moist curing, the products are stacked and kept wet for 7-10 days, then dried.
