Historic EventsImportant stories from Diamond-Drives history.
Drives Variable Speed Machine Used in 1969 Flood
As water rises due to the springtime snow melting, flooding is always a concern in river towns like Fulton, Illinois and Clinton, Iowa – where our facilities are located. Going down memory lane, we remember a time where Drives used their variable speed machine to fill 4,300 sandbags per hour.
Sand was dumped from trucks onto a conveyor and dropped into a hopper. Bags were fitted under the hopper tube and held in place by spring clips. After the bags were filled, they were put onto another conveyor and sent out to waiting trucks. The trucks then carried the bags to emergency sites along the river.
