Are you asking about this in addition to the typical dead load and snow load?
No problem. I will get back to you this evening with the results.
The W18x50 will work for the existing load + a 5,000 pound load 8' from the ends provided the top flange is continuously braced and the steel is Gr. 50. This is good for L/240 deflection.
