Description

technical field

[0001] The invention belongs to the field of water conservancy machinery manufacturing, and is especially suitable for the situation that the fixed hoist hoist and the fixed screw hoist with manual devices have to be manually operated due to lack of power supply in water conservancy and hydropower projects. Background technique

[0002] In water conservancy and hydropower projects, electric winches are usually used to open and close the gates. However, in rainy and thundery flood seasons, the power supply of the hoist sometimes fails due to lightning strikes, or the electric winch itself fails, causing the gates to fail to lift. In order to prevent the failure of the electric winch or the failure of the gate to lift due to power failure, fixed winch hoist and fixed screw hoist with manual device are installed on site. However, the fixed hoist hoist and fixed screw hoist with manual devices have low efficiency. When the flood comes, large-scale flood disasters...
