The FK36(r) and Pak 36(r) both had a split-trail carriage with a transverse leaf spring axle suspension, and steel wheels, with foam rubber filled tires. The guns were equipped with a semi-automatic vertical breech block; the recoil mechanism consisted of a hydraulic recoil buffer and a hydropneumatic recuperator. There was no limber; therefore the gun could not be towed by a horse team.
