随着我国水利水电建设事业发展,用于水利水电工程中闸门启闭设备需要不断地更新发展。闸门启闭设备需要满足不同工况控制功能和更高的安全运行要求,在不同类型的启闭机中,固定卷扬启闭机由于在起重量和扬程方面有宽广的适应范围,因此使用较为广泛,大多用于操作靠自重或加重关闭 With the development of China’s water conservancy and hydropower construction, the gate opening and closing equipment used in water conservancy and hydropower projects needs to be continuously updated and developed. Gate hoist equipment needs to meet the different conditions of control functions and higher safety requirements, hoist in different types of hoist, hoist hoist due to the lifting capacity and lift has a wide range of adaptation, so the use of more Wide range, mostly for operation by weight or aggravate the closure
