Ingersoll Rand beam trolleys are designed to work on a wide range of tapered S beams and Wide flange W beams. (Please see our Rail Systems Components section, under Rail Systems, for trolleys that fit our enclosed rail.) Trolleys are normally used to suspend a load and allow it to traverse along a beam. Typically a hoist is attached, via a hook or a lug suspender to the trolley. Ingersoll Rand trolleys come in plain push style, hand geared, and air motor driven. Most of our trolleys can be used on their own and adapt to most manufacturer's hoists. Some are dedicated to Ingersll Rand brand hoists. For bridge retrofit work, we even offer Man Rider™ trolleys suitable for holding suspended work platforms with people on board.
