Is it strong enough

Dear Sir:
I am in the process of building a gantry crane
using a 13' H beam 4"X4 " 1/4" thick web. The working length will be approx 11 feet. I have a one ton trolley and a 1350 lb hoist also one ton chainfall. I am trying to find out if this beam will support the one ton load in the center of the beam with some degree of leeway. This beam is new and not warped or bent. Thank your your reply will be appreciated.

I think for safety's sake, you need to put this question to a structural engineer.

we have one at work about that is an 8 inch I beam H beams are not normally used for this application as most trolleys are designed to run on the beveled edge of the I beam
