Manitou MT – how lift height and capacity hide inside the model number
Manitou's MT range is the French manufacturer's classic telehandler line for construction and agriculture, spanning lift heights from 4 to 18 metres and capacities from 2 to 4 tonnes. Both figures are encoded in the type number at once: on the MT 420 H, the "4" reflects a 4.35 m lift height at 2,000 kg capacity; the MT 625 H offers 5.85 m and 2.5 t; and the large MT 1840 reaches 17.55 m at 4 t — so the first digit group roughly codes lift height in metres, the second capacity in hundreds of kilograms.

Suffix letters such as "H" mark particularly compact, manoeuvrable versions for tight sites, while lines like MT-X or MRT (rotating telehandlers) form separate sub-ranges for extended reach or 360° slewing.
Models recorded in the database span engine outputs of 18 to 159 kW, own weights of 1,154 to 28,350 kg, and displacement of 1,147 to 6,600 cm³ across 3 to 4 cylinders — the bucket therefore covers everything from compact farmyard telehandlers to heavy construction machines, represented by models such as MT 523, MT 620, MT 732 or MT 932.
When buying a used telehandler, the condition of the telescopic boom and its slide pads, plus the lift and tilt hydraulic cylinders, matter most — play in the fully extended boom is a typical wear sign. It's also worth checking the load chart: the stated rated capacity only applies at short reach, and the permissible load drops sharply as the boom extends.

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.
