美军工程师团已研制成功一种新型的弧型闸门启闭系统,与传统方法相比同样有效,而且更经济。这种新型的启闭系统除能够获得更大的经济效益外,还大大简化了闸门操作的土木结构。传统的弧形闸门启闭机械包括闸门两端的缆索和卷筒。卷筒由一台电动机和齿轮传动装置操作。采用这种启闭方式,启闭机械 The US Army Corps of Engineers has successfully developed a new type of arc gate opening and closing system that is equally effective and more economical than traditional methods. In addition to being more cost-effective, this new hoist system greatly simplifies the civil engineering of gate operations. The traditional arc gate hoist machinery includes cables and drums at both ends of the gate. The drum is operated by a motor and gear unit. Using this way to open and close, open and close the machinery
