The JLG 1850SJ is an engine-powered telescopic Ultra Boom built for work that demands extreme height, long outreach, and rough-terrain mobility. With a 185-ft 7-in platform height, 80-ft horizontal outreach, and telescoping jib, it gives crews a large 2.9 million cubic-foot work area for positioning around tall structures and complex jobsites.
Full-time four-wheel drive, three steering modes, and drive-out extendable axles help the machine move and set up efficiently in demanding outdoor environments. Operators also get enhanced platform controls with an LCD work-envelope display, while service teams benefit from practical access features such as gull-wing steel hoods and a swing-out engine tray.
