7.5 ton free standing bridge crane
all,
can anyone tell me if and where you can purchase a 7.5t free standing bridge crane off the shelf?

what do you mean by free standing? do you mean gantry?

if that refers to unbraced columns, then yes.  i wasn't aware of the termonology. do you know of any mfgr's off top your head.
mi jack makes rubber tired gantry cranes.  but the smallest one listed is 18 t.
it sounds like you might mean a pedestal crane? if so, try the following:
a freestanding bridge crane is one that doesn't rely on building supports (except for floor/foundation).  columns and runways are stationary, and a traveling bridge provides motion in the longitudinal 'y' direction.  
with a gantry crane, the entire crane rolls on wheels for 'y' motion.
for both,  transverse 'x' motion is provided by trolley-mounted hoist(s) traveling along the bridge or gantry cross-
