Technical data of crane overload limiter

Technical data of crane overload limiter
Main technical data
1, early warning function: when the weight is greater than or equal to 90% rated weight, a low frequency sound and light alarm.
2, alarm and protection: when the weight is greater than or equal to 100% of rated weight, a high frequency acousto-optic alarm, if a certain period of time delay (which can be manually set), did not eliminate the alarm is automatically broken open up circuit, ban lifting action, issued at the same time, continuous sounding the alarm and alarm indicator lamp frequency flicker.
3, the immediate protection: when the weight is greater than or equal to 105% rated weight, immediately cut open up circuit, ban lifting action, also issued a ringing the alarm and alarm indicator lamp frequency flicker.
4, the overload number of records: Crane in the normal work, the number of overload records.
5, the total working time record: the total working hours of the crane records.
Note
1, in the light of the application circuit examples through CT1 coil power line and receiving limiter No.1 terminal power supply line for the same phase, otherwise the limiter is unable the normal work must be.
2, the limiter should be used after the installation of heavy load test, has verified the reliability of the product.
