Spiro Conveyor Floor home  Technical  Features  Applications  More Information  How the Spiro Conveyor Floor works The principle of operation of the Spiro floor is the difference in friction between the floor and the cargo. In a lorry trailer, for example, the floor consists of 24 aluminium profile sections which can move lengthwise. These profile sections are split into three groups of 8 which are driven independently by separate hydraulic cylinders. The floor transports material by repeating a movement sequence with the hydraulic cylinders. The diagrams below explain the sequence: Stage1: The first group of aluminium floor sections moves back 150mm quickly. The cargo stays were it is. Stage 2: The second group of aluminium floor sections moves back 150mm quickly. The cargo does not move. Stage 3: The third group of aluminium floor sections moves back 150mm quickly. The cargo remains stationery Stage 4: All three groups now move forward 150mm simultaneously. The cargo is now advanced 150mm. The process now repeats itself.

This gives a much smoother movement and avoids a lorry digging into the ground when it is operated on a soft surface. When used in static applications such as MRFs and Compost facilities, the principle is exactly the same. However, the floors can be extended sideways by adding more bars and can also be extended to 50 metres in length. Contact us now by email or by phone on 01829 740913. TOP OF PAGE
