Considering my schooling and books are from the early 60's

I have not seen the new listings . When I did the bridge

cranes for my shop (79 & 80) I used the books I had from

college,must have worked as they have not come down yet

and I have definitely overloaded them some.

The old shop is 2 bridges with 2 beams each ,12 in with

8 in channel turned down for rigidety in 30 ft wide building.

The big shop 15 in with 6 in channel on side ( 46 ft building).

The second one in the big shop is 18 in single rail on the

same side rails . also the 15 in one is two rails about 2 ft

apart , as are the ones in the old shop. The 12 in rails came

from FT Hollird and were rated 2tons (built 1918 ) , Used the

12in with stiffener that were side rails for sides . Used the

15in side rails the were in the 5 ton section for the 46 ft

bridge . Sides were on 24ft spans , so when I built the shop

I put all of the sides on 12ft centers.
