JLG Industries, McConnellsburg, Pa., has built more 40-foot boom lifts for longer than any other company. The Model 400S boom lift is actually the JLG's fifth generation 40-foot boom lift, and this unit featured four-wheel drive and an optional oscillating axle, a feature the company pioneered back in 1981.
