Crane support systems
Crane support systems
(OP)
Looking at a crane system independant from the building structure. No clearance to brace overhead from runway to runway so columns will be cantilevered to resist horizontal forces perpendicular to runway. Is the bridge and the trolley mechanism strong enough such that the horizontal forces perpendicular to rail will be shared across the bridge to columns on both sides? Equal sharing?

Just my opinion, but I wouldn't want to count on the bridge alone.

In answer to the columns sharing the horizontal force - yes, equally shared if same stiffness each side. The horizontal load is 20% of the lifted load plus the weight of the trolley, including all accessories.

Timing has a lot to do with the outcome of a rain dance.
