Top Rider Single Girder
The top riding single girder crane is similar to the top rider double girder crane. It is usually lower capacity (10 ton and lower) and is often a less expensive way to get high hook travel. This is the case because only one girder is necessary for this crane to do it's job.
Top Rider Double Girder
When head room (the distance between the highest part of the crane and the lowest part of the building) is the issue, top rider cranes are usually the way to go. With a top rider double girder, you are able to get the higher lift capacities along with maximizing your head room.
Underhung Single or Double Girder
Under hung single girder cranes and under hung double girder cranes maximize the headroom of a building where it is an issue. The single girder under hung will give you less lift capacity than the double girder, but is more cost effective.
