The selection principle of screw hoist in terms of components
The selection principle of screw hoist in terms of components:
1. In the process of using the screw hoist, if there is no AC power supply, the alarm can be selected according to the DC power supply voltage used. For example, electric horns, transistor alarms, or sounders such as buzzers, etc., as long as they are in the limit switch, the rated current contact rod type can be used.
2. In the process of using the screw hoist, if you use a steel gate with AC electrical appliances and electric opening and closing, we can also choose electric horn, chang body tube alarm or buzzer in the selection process Yes, but for the alarm, we still determine the power supply according to the rated voltage of the selected alarm.
Whether it is on cast iron gates or on the selection of components of the screw hoist of steel gates, we need to pay great attention to it. Only when safety is ensured, we can work better.
