The JLG 400S is a self-propelled telescopic boom lift in the aerial lifts category, designed for elevated access in construction, maintenance, and industrial applications. It typically provides a working height of about 46 feet and a horizontal outreach of around 33 feet, depending on configuration. The 400S is commonly used for tasks requiring up-and-over access, such as steel erection, facility maintenance, and exterior installation work. It features a narrow chassis for maneuverability, proportional controls, and diesel or dual-fuel power options on many units. The model is part of JLG's 400 Series boom lift lineup.
