Abstract
A beam trolley having a width adjustment system includes a first side plate having two or more wheels configured to couple with a beam (which may have an I-beam, wide flange (W-type) I-beam, or standard (S-type) I-beam configuration). A second side plate having two or more wheels coupled thereon is configured to couple with the beam. A main load bar couples with the first and second side plates and includes a threaded shaft having a first alignment surface. A threaded hand wheel couples with the threaded shaft and is configured to move the threaded shaft relative to the first and/or second side plate(s) in response to manual rotation of the threaded hand wheel to adjust a distance between the first and second side plates. An aligner couples with one of the side plates and includes a surface engaging the first alignment surface to prevent rotation of the main load bar.
