螺杆式启闭机在操作过程中应注意的事项：
Precautions during operation of screw hoist:
首先，要检查电源和备有电源。螺杆式启闭机工作是需要三相电的。在工作前首先要确保的是电压的稳定以及三相电的充足。电源指示上启闭的运行状态是否与电源指示一致。
First, check the power supply and standby power supply. Three phase electricity is needed for the operation of screw hoist. The first thing to ensure before work is the stability of voltage and the sufficiency of three-phase power. Check whether the operation status of the upper opening and closing of the power indicator is consistent with that of the power indicator.
其次，在螺杆式启闭机运行过程中要要确保启闭机和闸门的配合程度，当闸门处于开启状态时，禁止动制动设备和固定螺丝。
Secondly, during the operation of the screw hoist, it is necessary to ensure the cooperation between the hoist and the gate. When the gate is in the open state, it is forbidden to move the brake equipment and fixed screws.
当螺杆式启闭机超过一定的高度时候要将润滑部位的螺丝拧紧，防止出现故障。若在中途发生故障，要马上停止工作，待电源关闭后进行检查。
When the screw type hoist exceeds a certain height, the screws at the lubrication part shall be tightened to prevent failure. In case of failure in the middle of the process, stop working immediately and check after the power is turned off
