If the customer requires a ceiling hung system then the ceiling beam size is important because it tells the manufacturer what size beam hangers are required to hold up the runways.

Ceiling height or max height (how to quote a crane system)
The ceiling height or max height isn't really that important. All it pretty much tells the manufacture is: how much height there is to work with. This is only important when the customer doesn't know the height they need to lift/move a specific product.
Doesn't get any easier.

Raised Bridge Ends
When we talk about hook height, we are talking about the elevation at which the hoist hooks to the trolley on the bridge. LET ME REPEAT THIS - THE HOOK HEIGHT IS THE ELEVATION AT WHICH THE HOIST HOOKS TO THE TROLLEY IN THE BRIDGE.
In most crane applications the hook height is extremely important. Hook height is extremely important because people want to have the ability to lift something as high as they need to. They might want to lift something 20ft into the air, or they might want to lift something 3ft into the air. It all depends on the application. But one thing still remains certain - people want the highest hook height they can get.
This is where there is a conflict. See, 95% of our customers (roughly 1 million) install cranes inside a warehouse, shop, what-have-you. The problem is simple: The roof sometimes does not allow them to reach the hook height that they want with a normal system. This is when we go above and beyond (no pun intended).
When the roof is low and a high hook height is needed, we offer a solution called raised bridge ends. Raised bridge ends do exactly what it says - it raises the bridge ends so that the bridge is in the same plane as the runway. I'll just show you a picture... So there you have it, our solution when you need to achieve the highest hook height.

Bays and Multiple Bridges
Systems can utilize multiple bridges. The systems just have to have a capacity rating high enough to accommodate the weight if both bridges we MAX loaded. This is where it gets a little complicated.
If you want the two bridges to be able to travel in the same bay, the bay must be rated to accommodate both bridges MAX loaded.
If you have multiple bridges, however, and stop the bridges from entering the same bay together (In other words, you will never have a bay with more than one bridge in it), each bridge can be rated at 6,000lbs (if we follow the two above examples). Bridges can be stopped from entering bays by installing what's called "runstops" inside the runway. Runstops prevent bridges from traveling any further.
