(NTH4-11026, Serial No. 0046636). The NTH series combines a hand chain hoist with a manually-operated push trolley in a single unit, eliminating the need for a separate trolley and hoist assembly; the trolley rides on the bottom flange of an I-beam or monorail and is hand-pushed laterally while the hoist lifts the load vertically via a Grade 80 alloy steel load chain.
