Electric hoist limiter relevant safety technology

 Overload limiter is safe to use electric hoist one of the essential parts, played a limited role overload,manual block the following with you to understand the relevant safety limiter technology.
1, overload limiter Scope: 0.5T ~ 32T kinds of electric hoist single girder cranes;
2, the system error: less than ± 5% (F.S);
3, the sensor static strength: the strength of the sensor is 1.5 times the rated load;
4, the overload limiter operating temperature: -20 ℃ ~ +60 ℃;
5, relative humidity: 45% ~ 95%;
6, overload limiter power supply voltage: AC380V, 50HZ or according to user requirements;
7, the relay contact capacity: relay contact capacity AC380V, 2A;
8, the controller of the pressure:lever hoist to 2000V;
9, display: four LED (red) from the weight of the digital display, the decimal point is 2.
10, electric hoist overload limiter warning mode: sound alarm;
(1) Pre-alarm: When the rated lifting weight lifting weight of 90%, the issue of intermittent alarm sound (short beeps), indicating heavy weight;
(2) Ratings alarm: When the rated lifting weight lifting weight of 100%, the issue of intermittent alarm sound (long beeps), indicating heavy weight;
(3) immediate alarm:wire rope winch When the rated lifting weight lifting weight of 110%, emits a continuous alarm sound, the red indicator light, and automatically cut off the power supply contactor crane rising, indicating heavy weight;
