船只在通过通航建筑物 (船闸或升船机 )时 ,不可避免的会碰撞通航建筑物 (船闸或升船机 )上的有关设施。在工程应用中 ,设置防撞装置的方法很多 ,但是 ,采用钢丝绳两端设置缓冲油缸的方式在国内工程应用中还很少见。这种防撞方式简单、可靠、安全 ,并且所需要的空间也较小 When a vessel passes through a navigable building (a lock or a ship lift), it inevitably collides with the relevant facilities on the navigable building (lock or ship lift). In engineering applications, there are many ways to set the anti-collision device. However, adopting buffer cylinders at both ends of the steel wire rope is still rare in domestic engineering applications. This method of collision avoidance is simple, reliable, safe and requires less space
