HAHN Gasfedern developed special double-stroke springs for heavy flaps with a large opening angle, which are characterised by a low starting and a high ultimate force. These springs have two pressure cylinders that can be filled differently and thus are able to cover two force ranges. The compression of the piston rod generates a bent characteristic curve, which can be better adjusted to the force progression of the flap. Double-stroke springs are specially designed for the application you require.
The force ranges are exactly attuned to each other and adapted to the requiredkinematics.
HAHN double-stroke springs are available in steel, in AISI 303/304 and AISI 316L/316Ti.
