XCMG – other models: the collective page of mobile and rough-terrain cranes outside the named ranges, QY and XCT truck cranes from 16 to 100 tonnes capacity, 170 to 324 kW
This page gathers the XCMG cranes the register could not assign to a named range – truck cranes of the QY range, from the QY16G.5 to the QY100K, and the XCT range, from the XCT25E to the XCT70E. XCMG, the Xuzhou Construction Machinery Group from the eastern Chinese city of Xuzhou in Jiangsu province, traces back to a plant founded in 1943 and is today among China's largest construction-equipment makers. The number in the type designation gives roughly the lifting capacity in tonnes – the QY100K reaches the range's highest capacity, the QY16G.5 its lowest – the letters K and B and the suffixes G.5, K-II and K5-I mark different chassis and boom versions.

The register lists here 11 versions with 170 to 324 kW, operating weights from 24,000 to 58,000 kg, lifting capacities from 14,515 to 100,000 kg and engine speeds from 1,800 to 2,200 rpm.
XCMG is, alongside Sany and Zoomlion, one of China's three big crane makers and has built a name for itself outside China too with the QY and XCT ranges; the truck cranes compete in the mid and upper tonnage segments with Liebherr, Tadano and Grove.
When buying used, what matters is the condition of the boom telescope and the wire-rope winches, the hydraulic cylinders for outriggers and boom lift, engine and transmission hours, and the condition of tyres and axles; spares and service run through XCMG's Chinese dealer network, which is being expanded in Europe.

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.
