It is fully bufferde, high-frequency, low amplityde, pneumatic-type molding machine microseism compaction. It used a buffer spring, pneumatic microseism institutions can reduce the shock impact of the foundation.
All parts of the aircraft fuselage steel, a substantial increase of steel. Chun-pressure aircraft body table, shock pistons, shock compaction iron piston, cylinder composed of compaction. Pressure head to arm it in part by the pressure head plate, tumbler beam, the center gear shaft, piston cylinder, such as rack of the tumbler cylinder by the driver at both ends buffer agencies so that a smooth transfer arm rotation. Mode since the aircraft structure, by the connecting rod from cylinder mode axis synchronization, push mode, such as starting composition, the use of air pressure from the oil cylinder mode control to ensure a smooth beginning.
