Lifting weight limiter, a kind a lifting weight machinery security protector, can be used for 5 to 75t bridge crane, door crane, on-off crane and other lifting equipments. It is composed of strain gauge load cell and electric control meter.

The lifting weight limiter meter adopts single chip-controlled technology. Its main functions are that measuring and indicating the lifting weight timely as connecting the signal of sensor, sending out acoustic-optic alarm, outputting control signal and cutting off the rising looping power supply when weight reaches the stipulated value. Meanwhile, its characteristics are that indicating weight accurately, deb ing conveniently, enacting high-low distinguishing rate and setting power supply to resist surge circuit, etc.

* The limiter main technical parameter is better than that of GB12602-90 Lifting machinery over load security protector
* The sensor with axle-shell, base seat and joined with model KQC meter is the most common used type of lifting weight limiters.
* Model BTW-X series sensor, mainly installed under bearing seats and other structures as well, is a kind of measuring pressure sensor.
* The bearing seat sensor matched to the large-tonnage limiter is made according to the users requirements.
