Installation steps of side roll hoist:
側搖啟閉機的安裝步驟：

(1) When installing the screw opening and closing, be sure to keep the base foundation layout plane 180o level;
（1）在安裝螺桿啟閉機時一定要保持底座基礎布置平面水平180o；

The contact area between the base of the hoist and the foundation layout plane should reach more than 90%;
啟閉機底座與基礎布置平面的接觸面積要達到90%以上；

The axis of the screw should be perpendicular to the horizontal plane measured on the brake platform;
螺桿軸線要垂直閘臺上衡量的水平面；

It should be vertical with the damper ear hole to avoid the screw tilt, causing local force and damage to the parts.
要與閘板吊耳孔文和垂直，避免螺桿傾斜，造成局部受力而損壞機件。

(2) Place the manual screw hoist in the installation position.
（2）將手動螺桿啟閉機置于安裝位置。

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器中，當螺桿從機器的上方露出后，再套上限位盤。

The lower part of the screw is connected to the gate.
螺桿的下方與閘門連接。

(3) The foundation for installing the hoist must be stable and safe.
（3）對于安裝啟閉機的基礎必須穩固安全。

The concrete of the frame and foundation members shall be poured according to the provisions of the drawing. When the strength of the concrete does not reach the design strength, the temporary support of the hoist shall not be removed or changed, and the test and test operation shall not be carried out.
機座和基礎構件的混凝土，按圖紙的規定澆筑，在混凝土強度未達到設計強度時，不準拆除和改變啟閉機的臨時支撐，更不得進行試調和試運轉。
