Our over and under tote exchange systems provide a multiple container feeding system for assembly lines and work cells. These systems have a smaller foot print than a side by side system. The containers are loaded on the lower level and present in an ergonomic position to the operator. Once filled or emptied, the containers are raised and discharged to the upper level outbound lane. Each unit is custom made and can handle up to four totes inbound and four totes outbound. These units handle automotive style totes and containers. The system can provide tote exchange in as little as 30 seconds and can be gravity or fully powered in all positions.
