SQX-2B type lifting weight limiterDetailed product description：

The SQX-2B type lifting weight limiter consists of two parts: sensors and electrical control instruments. It is a widely used safety protection device for lifting equipment such as bridge cranes, gantry cranes, and hoists. Instruments can be used in conjunction with various forms of sensors. Due to user needs, a series of non-standard functional instruments have been derived from the SQX-2B instrument. To facilitate differentiation, the following table (as shown in Table 1) has been developed.  

Table 1

Serial Number	name and model	Technical Requirements
one	Precision	Display accuracy ≤ 5% F.S, action error ≤ 3% F.S.
two	Forecast Alert	90% of the rated lifting capacity will sound and light an alarm.
three	Delayed alarm	Continuous sound and light alarm at 105% of rated lifting capacity, delayed relay action for 1-2 seconds, cutting off lifting power supply.
four	Call the police immediately.	The 130% relay of the rated lifting capacity immediately activates to cut off the lifting power supply.
five	working power supply	220V or 380VAC, 50Hz
six	working environment	-20% ~ +60%、≤90%RH
seven	Protection Rating	The sensor is IP65 and the instrument box is IP42.
eight	Sensor overload capacity	1.5 times the lifting capacity.
