Hydrokran Saturn: heavy crane vehicle with a gross vehicle weight of 20,000 kg, an unladen weight of 19,620 kg and a 3,100 mm wheelbase
The designation "Hydrokran" denotes a hydraulically operated crane on a chassis, and here describes a vehicle type rather than a manufacturer's brand. Nothing certain can be said about the name "Saturn" for this vehicle, but the figures clearly paint the picture of a heavy piece of work equipment.

At a gross vehicle weight of 20,000 kg and an unladen weight of 19,620 kg, only around 380 kg separates the two, meaning virtually the entire weight sits in the permanently mounted crane body rather than variable payload. Wheelbase and width are 3,100 mm and 2,500 mm respectively, spread across four wheels.
At 20,000 kg the vehicle belongs to class N3 for trucks above 12 tonnes. The fact that the entire weight capacity is taken up by the crane body itself is typical of hydraulic cranes on a chassis: the vehicle does not primarily transport goods but provides a lifting device at changing work sites.
For a used crane vehicle of this kind, the hydraulics are the main focus: check cylinders and the boom for leaks and wear, the outriggers for correct operation, and the supporting structure for cracking. On the chassis, with only four wheels carrying 20 tonnes gross weight, the condition of the axles, tyres and brakes matters especially, since these are under unusually heavy load, and early wear on them can be hard to spot without lifting the vehicle.
