The Strabokran (Strassen bock kran, or road gantry crane) consisted of a horizontal gantry supported by a pair of collapsible support towers. The gantry housed a winch on a rail-mounted trolley. A motor was mounted at one end for powered lifting, and a hand-powered chain wheel was mounted at the opposite end for driving the horizontal movement of the trolley. Each of the twin support towers consisted of four hinged scissor-sections, which were erected by cables via a hand-cranked winch mounted in the base of each tower, and then locked together. Strabokrans with 15t, 16t and 20t lifting capacities were developed in different years, and were towed by SdKfz 8 and SdKfz. 9 halftracks. Approximately 100 Strabokrans were built, some of which were license-built at the company Stratenwerth in Duisburg until the war's end, and were supplied to units equipped with Tiger’s, Panthers, as well as V2 units.
