The selection principle of screw hoist in terms of components

Screw hoist is widely used in cast iron gate. Because of its simple structure, simple installation, low price, etc., it is loved by many users. However, if in terms of machinery, if you choose not carefully, it will pose a great threat to the safety of operators. So, how do we choose between the screw hoist and the parts?

1. In the process of using the screw hoist, if it is used without AC power, its alarm can be selected according to the DC power voltage used. For example, electric horns, transistor alarm machines, or those buzzers and other audio machines, as long as they are in the limit switch, the extra current 5A touch rod type is enough.

2. In the process of using the screw hoist, if a steel gate with an AC motor and an electric hoist is used, we can also choose an electric horn, a chang body tube alarm or a buzzer during the selection process However, for the alarm machine, we still determine the power supply according to the additional voltage of the selected alarm machine.

Whether it is in the cast iron gate or in the selection of the mechanical parts of the screw hoist at the steel gate, we are required to pay attention to it. Only when safety is ensured, we can better work and use.
