A proven product since 1998, this unique flatbed trailer enables the lower deck area to be extended in length (incremental positions throughout). The patented air powered stinger simplifies disconnecting and connecting while optimizing operator safety. No blocking required. A flexible track incorporating the air and electrical connections prevents the need for connecting and disconnecting during deck extension. It also prevents pinching or crushing those components. Some competitive offerings do not have this feature. This provides years of trouble free functionality of these systems in addition to easy access for maintenance over the life of the trailer.
