啟閉機按吊點數分為單吊點和雙吊點兩種型號,按驅動方式分為手動、電動和手電兩用三種形式。一般啟門重量超過600KN（單機）時不再配置手動部分。我公司生產的QL型系列啟閉機啟門為3KN－650KN，超過650KN（單機）時可特殊設計。
The hoist is divided into two types based on the number of lifting points: single lifting point and double lifting point. It is divided into three types based on the driving method: manual, electric, and dual use. Generally, when the weight of the door opening exceeds 600KN (single machine), the manual part is no longer configured. The QL series hoist produced by our company has a door opening range of 3KN to 650KN, and can be specially designed when it exceeds 650KN (single machine).
型號說明：等同采用水利標準統一標準型號標識（下同）
Model description: It is equivalent to using the unified water conservancy standard model identification (the same below)
本系列啟閉機未作特殊設計時，不能作斜吊運行。
When this series of hoists is not specially designed, they cannot be used for oblique lifting operation.
手電30KN以上的啟閉機可增設行程限位裝置，作運行保護。手動啟閉機均設有限運盤，作為下降位置控制。
A travel limit device can be added to the hoist with a flashlight of over 30KN for operation protection. The manual hoist is equipped with a limited transport plate as the lowering position control.
閘門吊耳部分應根據啟閉機螺桿外形設定。特殊情況定貨前應聲明。
The lifting ear of the gate should be set according to the shape of the hoist screw. Special circumstances should be declared before ordering.
