 Based on the NSU Sd.Kfz.2 "Kettenkrad" light tracked vehicle, NSU Werke at Neckarsulm developed and built around 50 Springer demolition vehicles in the final year of World War II.To make the vehicle capable of carrying a bigger payload without the motorcycle-style front fork of the original, two pairs of overlapping and interleaved road wheels were added to the aft end of the running gear on each side; giving three outer and three inner running wheels.
