彈簧鎖（排氣鎖）
在上述錐環作用在彈簧力由一個楔效應放大，并傳送所有被布置在許多鋼球的
兩個圓圈。這些作用于閘瓦保持件和制動，其通過擰緊對著它以較大的力將鎖定活塞桿。
當空氣壓力供給到鎖定解除端口解鎖完成。制動活塞和錐度環反對彈簧力，向右移動
側，和球保持器撞擊蓋部A作為鋼球從由球保持件的錐環除去制動力被解除。

Spring locking (Exhaust locking)
The spring force which acts upon the taper ring is magnified by a wedge effect, and is conveyed to all of the numerous steel balls which are arranged in
two circles. These act on the brake shoe holder and brake, which locks the piston rod by tightening against it with a large force.
Unlocking is accomplished when air pressure is supplied to the unlocking port. The brake piston and taper ring oppose the spring force, moving to the right
side, and the ball retainer strikes the cover section A. The braking force is released as the steel balls are removed from the taper ring by the ball retainer.
