When the top of the gate is exposed, it is necessary to connect the basic installation plane of the base 180;
閘門的上方露出后在裝置螺桿啟閉機時必然要連結底座根本安插平面程度180；

The contact area between the base of the hoist and the basic installation plane should reach more than 90%;
啟閉機底座與根本安插平面的接觸面積要到達90%以上；

The degree surface of the screw axis to be balanced vertically on the brake platform;
螺桿軸線要垂直閘臺上權衡的程度面；

It should be stable and vertical with the gate hanging ear hole to avoid the tilt of the screw, forming local force and damaging the parts.
要與閘板吊耳孔穩和垂直，避免螺桿傾斜，形成局部受力而損壞機件。

2, steel gate manual screw opening and closing machine is placed in the device position.
2、鋼制閘門將手動螺桿啟閉機置于裝置位置。

Put a limit disc on the screw, screw the screw from the lower part of the beam into the machine, and when the screw is exposed from the top of the machine, then set the upper limit disc.
把一個限位盤套在螺桿上，將螺桿從橫梁的下部旋入機械中，當螺桿從機械的上方顯露后，再套上限位盤。

The lower part of the screw is adjacent to the gate.
螺桿的下方與閘門毗連。

3. Deal with the fundamental stability and safety of the device opening and closing machine.
3、對付裝置啟閉機的根本安定平安。

The concrete of the frame and the fundamental member shall be poured according to the delineation of the drawing, and shall not be subjected to trial and harmonious test run when the strength of the concrete does not reach the envisaged strength.
機座和根本構件的混凝土，按圖紙的劃定澆筑，在混凝土強度未到達設想強度時，更不得進行試和諧試運行。
