This is a Columbus McKinnon (CM) Series 632 Low Headroom Push Beam Trolley, model code 3222, rated at 1/2 ton (500 kg) capacity, manufactured in the USA and listed in new-other condition in original CM packaging. The trolley features four ball-bearing wheels with 2-3/4" diameter steel wheels that ride directly on the bottom flange of a standard I-beam, accommodating flange widths from 2-5/8" to 5-1/16" and compatible with 4" to 12" I-beams with a minimum 7" radius curve. The low headroom design minimizes the distance between the beam and the hook, making it well-suited for facilities with limited vertical clearance; the adjustable side plates (visible in photos with hex-head adjustment hardware) allow field adjustment to fit the beam flange width without special tooling. Each trolley includes two tapered flange-retention nuts (visible as separate components in photos) and is labeled per ASME B30.16 and B30.11 standards.
