That is a prototype of a "Räumer-S" by Krupp.
This vehicle was built to clear mines by detonating them. It had a weight of 130 tons. Two identical half-vehicles (except for width) each driven by a 360 hp Maybach motor were conntected in the middle by a hydraulic coupler. The length of the vehicle was 15,63m, it was 2,93m high, the wheels were of 53cm width with a 2,7m diameter and 15cm strong rubber pads. The width of the vehicle was up to 3,27m (with the purpose of the wheels clearing a broader parallel path). Detonations were to be coped with by a 1,1m range of spring. The main problem was high ground pressure which made it ill suited to offroad movement. The picture was taken at Hillersleben proving ground, where it was captured.
