The JLG 1200SJP is an aerial work platform from the boom lift series manufactured by JLG. This model belongs to the category of boom lifts and is referred to in English as an aerial work platform. The designation SJP indicates a telescopic boom with an additional basket jib, which increases the reach in open terrain. The machine is designed for use in areas requiring high vertical reach combined with large horizontal outreach.
With a length of 13,440 mm and a width of 2,500 mm, the vehicle imposes specific requirements on transport logistics and space conditions on the construction site. The empty weight of 18,551.9 kg requires a load-bearing surface to safely distribute the weight. The gradeability of 45% enables the machine to handle inclines that exceed the level of flat surfaces. The onboard voltage of 12 V supplies the electrical systems, while the hydraulic oil volume of 208.2 l controls the movements of the boom and the basket. The foam-filled tires in size 445/500710 offer a puncture-proof solution for hard surfaces.
Within the series, the 1200SJP ranks 7th out of 64 models with specified empty weight. The next smaller model is the 860SJ with a weight of 16,433.7 kg, while the next larger model, the 1250AJP, weighs 19,958 kg. The entire range of the series spans from 1,542.2 to 27,351.6 kg. This classification shows that the machine is positioned in the upper range of the lighter to medium weight group, significantly heavier than smaller telescopic platforms but still below the heaviest articulating boom variants.
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.
