The primary component of the steel sluice gate: The gate hinge is designed with a cylindrical hinge, made of material ZG310-750. The sleeve is made of ZQA9, and the hinge bearing is a journal bearing. The hinge serves as the rotational center during the opening and closing of the gate leaf. The fixed part of the hinge is secured to the base plate with anchor bolts, while the movable part is connected to the gate leaf structure with bolts. It withstands the total water pressure, the weight of the gate leaf, and the external forces such as the opening and closing forces during the opening process, making it a critical component for the opening and closing of the flip bucket gate.

The maximum load of the hinge should occur when the gate is just opened. This gate withstands the water pressure, the force to open the gate, and the weight of the gate itself, all of which are borne by the hinge. Each gate opening has multiple hinges, which are distributed at different positions based on the width of the opening.

The gate has been launched using hydraulic open/close machines at both ends. The hydraulic steel坝gate open/close machine features a horizontal hinge-supported structure. The bearing hinges are equipped with bronze-based self-lubricating bearings, while the oil rod ends are fitted with lubricated joint bearings. The oscillation point along the radial centerline of the joint bearings compensates for the installation errors between the open/close machines, the gate, and its embedded components. The joint bearings are designed with excellent sealing. One end of the open/close machine is connected to the bottom shaft arm, which is moved by the piston rod of the open/close machine to open and close the gate body.
