Performance Analysis of Preowned SANY STC250C51 Truck Crane

A 2020 SANY STC250C5-1 is a 25-ton truck crane with a moderate-use profile in the secondary equipment market, according to its listed operating data. The unit shows approximately 4,300 working hours and 12,900 kilometers, figures that place it in a middle range for equipment of its class. Those readings are relevant to assessments of remaining service life and maintenance exposure.

The crane was manufactured in November 2020 and has a relatively high market presence among 25-ton truck cranes. Its accumulated operating time of about 4,300 hours and odometer reading of 12,900 kilometers indicate medium-intensity use in recent years, a factor that can inform evaluations of component wear and residual value.

The STC250C5-1 is configured around a 42.5-meter main boom and a 5.9-ton counterweight, which together support its 25-ton rated lifting capacity. Its operating weight is 34 tons, placing it in a conventional class for road-mobile lifting equipment.

The machine meets the Euro V emissions standard and is powered by a Shangchai 300-horsepower engine paired with a nine-speed synchronized transmission. The drivetrain is positioned as a balance between power output and fuel economy, while the hydraulic system uses an Italian Casappa pump tied to the model’s lifting stability and hydraulic reliability.

The combination of the 42.5-meter main boom and 5.9-ton counterweight forms the basis of the crane’s 25-ton rated lifting capability. The Casappa hydraulic pump is a central element in the model’s hydraulic reliability, supporting smooth lifting and luffing operations.

For used-crane evaluation, inspections typically extend beyond headline specifications. Key checks include pressure stability in the hydraulic pump and smooth shifting through the transmission synchronizers, both of which can reveal condition issues that are not apparent from operating hours alone.

Because the STC250C5-1 is a mature model, its parts supply channels are relatively broad, which can lower later maintenance costs. Routine lubrication checks on the Handan-produced heavy-duty axles are also identified as important for stable travel in complex job-site conditions. The model’s standard component set and parts availability remain central to its maintenance profile.
