The product range is divided into four main groups (Size 1, Size 2, Size 3 and Size 4), for increasing ship sizes. The units are available in different versions. Depending on the size, they can be delivered as road-mobile, road capable, dock mobile, gantry mounted or skid mounted units. The road mobile units can be transported on public roadways. The road capable model has to be disassembled partly before the transport.

The dock mobile units are mounted on a trailer or mobile platform with rubber wheels. These units are too big for transport over the road. They can be transported within the port, for instance from the unloading position at the dock to a parking spot (if the dock has to be cleared after the unloading has been completed). The gantry mounted units, have bogie sets for traveling over rails. All sizes can be delivered as skid mounted units, for fixed locations. Alternatively, the skid mounted units can be mounted on a barge for unloading at different locations that can be reached over water or to cope with large tidal differences. Where practical, the new standard units use the same components, maximizing the advantages mentioned above (e.g. reduced engineering time and cost, delivery time, documentation quality).
