JLG Boom Lift 400S to 740AJ (telescopic and articulating aerial work platforms) – S, SJ and AJ as boom type, a leading E for electric drive: engine output 5 to 65 kW, operating weight 3.5 to 26.4 t
On JLG models like the 400S, 460SJ or 740AJ, the number roughly tracks platform height in feet, while the letter code describes the boom type: "S" marks a straight telescopic boom, "SJ" a telescopic boom with an added basket jib, and "AJ" an articulating boom with a jib. JLG itself describes telescopic booms as reach specialists for distance and open ground, while articulating booms trade some reach for a more compact footprint around obstacles. As with other manufacturers, the quoted working height sits above bare platform height, since it factors in the reach of a standing operator on the platform; actual platform height is correspondingly lower than the model number suggests.

Models with a leading "E", such as the E26MJ, E33MJ or E600J, mark electric-drive lifts — as opposed to diesel- or gas-powered models like the 400S or 460SJ.
Platform capacity holds steady at 230 kg across the recorded SpecCodex data, matching comparable lifts from other manufacturers. Several models also share a recorded displacement of 2,900 cm³, pointing to one common engine fitted across multiple boom sizes.
When buying used, check for play in the telescoping boom's slide pads, inspect hydraulic hoses running through the boom, test the emergency-lowering system, and — on electric models — check battery condition. Hours on the clock and the service log deserve a look too.
In short: the number is a rough platform height, S/SJ/AJ describes the boom type, and a leading E marks electric drive.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
