Sany Hydraulic Truck Crane – the QY25C and the STC range from STC200 to STC750, 213 to 275 kW, 26 to 46 tonnes crane vehicle weight
Sany, founded in 1989 in Hunan and headquartered in Changsha, ranks among China's largest construction-equipment makers and among the leading truck-crane brands worldwide. The type logic: QY is the standardised Chinese abbreviation for a truck crane (a crane on its own chassis), and the following number gives the maximum lifting capacity in tonnes – QY25C is thus a 25-tonne crane. Sany's own STC range (Sany Truck Crane) follows the same logic: STC200 to STC750 denote capacities of 20 to 75 tonnes, with H marking a version with greater hook height.

The register lists here 6 versions with 213 to 275 kW, all from six-cylinder engines, crane vehicle weights from 26,400 to 46,000 kg, torque from 1,050 to 1,500 Nm and a rated speed of about 2,100 rpm.
Truck cranes in this class lift loads of 20 to 75 tonnes on building sites, at installation work and in civil engineering, and travel to the job on public roads on their own chassis. From the 2000s Sany's STC range competed against established suppliers such as Liebherr and Tadano and the Chinese rivals XCMG and Zoomlion, building the brand's share of the mid-capacity segment.
On a used truck crane, the condition of the telescopic boom and its sliding pads, the hoist winch and wire ropes, the hydraulic cylinders of boom and outriggers, the chassis and axles for road use, and the inspection history of the crane superstructure, which in most countries must be periodically examined by a qualified inspector, all count. Spare parts run through Sany's international dealer network.

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.
