today a salesman for air winches came by and showed us a catalog. the air winches have a point load without laterl moving cables. With more information (which we are waiting on) that could solve our problem. two air winches at 1/3 span will lower our moment...
A 24x229 is 26 inch deep with 13.1 inch flange of 1.73 thickness. with the unbraced length we got it can handle 1.47 Mft-lb of moment. It can handle the load pretty good. The beam was already purchased so we have to use it. Now accuratley analyzing the hoist and sheave at the bottom is the...

There are no lateral bracing for the beam and the columns are braced at...
