Especially, Yeswin is specialized in self locking gas springs for treadmills, and Yeswin has unique patented piston structure for such gas springs. Self locking gas springs, also called safety lock gas struts, are different from common compression gas springs, they have an external mechanical locking system. A support tube is fitted on the shaft end which pivot out, when the gas spring reaches the fully extended position. If the external load exceeds the gas spring force, the tube will support itself on the front side of the pressure tube thus preventing the shaft from compressing. To release the locking, the support tube must be removed from the locking position. Usually, such gas springs are used for lifting treadmills' decks.
