JLG telehandlers – capacity in pounds before, height in feet after the hyphen, plus the work platform and its own inspection duty for people
At US manufacturer JLG, better known for aerial work platforms, the type designation of the main telehandler range follows a simple two-value formula in imperial units: the first digit group gives capacity in thousands of pounds, the second the maximum lift height in feet. The 943 lifts 9,000 lb to a height of up to 43 ft; the 1055 lifts 10,000 lb to 55 ft.

Following the same pattern, the 1255 reads as a 12,000-lb machine with roughly 55 ft of lift height. Older or more compact lines in the database, such as 266, 307, 742 or 3507, do not follow this two-part logic in the same way and cannot readily be decoded against the same scheme.
Models recorded here span engine outputs of 55 to 104 kW, own weights of 4,990 to 15,921 kg, and lift heights of 5,500 to 17,300 mm, with engines of 2,900 to 4,501 cm³ displacement, mostly four-cylinder — a line-up of mid-size to large construction telehandlers.
Besides pallet forks, these telehandlers can also carry attachments such as a bucket, a jib with hook, or a work platform; when a work platform is used to carry people, separate inspection and approval rules apply to it, going beyond simply checking the base machine's capacity.
For a used machine, beyond boom and slide-pad condition, check the load chart: the rated capacity given in imperial units, as with any telehandler, only applies at short reach and drops noticeably as reach increases.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
