 The barrel recoiled normally in its cradle, but, in addition, the whole top carriage, which carried the barrel and its cradle, recoiled across the main part of the carriage.This system damped out the recoil forces and made for a very steady firing platform.This carriage was also used for the 17 cm Kanone 18 in Mörserlafette and the 15 cm Schnelladekanone C/28 in Mörserlafette.
