啟閉機設備選購需要注意：
Attention should be paid to the selection of hoist equipment:
1、選擇啟閉機，需注明手動或電動即可，無需另外注明啟閉機型號。
1. To select a hoist, it is necessary to indicate whether it is manual or electric, and there is no need to specify the hoist model separately.
2、寬度在1.5m以內，且深度合適時，可采用手提操作，采用電動單梁吊車(電動葫蘆、手動葫蘆)配抓落機構啟閉。
2. When the width is within 1.5m and the depth is appropriate, it can be operated by hand, using electric single beam cranes (electric hoists, manual hoists) with a gripping mechanism for opening and closing.
3、PZ型閘門可按啟閉力配用我公司生產的Q系列啟閉機，也可用卷揚式啟閉機、電動葫蘆配自動抓落機構的啟閉力應按啟門時的靜水壓力狀況區別對待。
3. The PZ type gate can be equipped with the Q series hoist produced by our company according to the opening and closing force, and can also be equipped with a winch hoist, electric hoist, and automatic gripping mechanism. The opening and closing force should be treated differently according to the static water pressure when opening the gate.
4、靜水啟閉(如某些檢修閘門，設有旁路放水系統)時，啟門力為門體自重，閉門力不考慮。
4. When opening and closing in still water (such as some maintenance gates with bypass drainage systems), the opening force is the weight of the gate body, and the closing force is not considered.
5、動水啟閉(如放水閘門，事故閘門)，啟閉力按鑄鐵閘門啟閉計算。
5. Dynamic water opening and closing (such as discharge gate and emergency gate), the opening and closing force is calculated based on the opening and closing of cast iron gates.
