JSL-C type lifting torque (overload) limiter

       ◆ Instrument chassis is beautiful and practical, and won the national design patent;

　　◆ LCD LCD screen backlight display, can be divided into working conditions (such as main hook/auxiliary hook, hook/grab, etc.) to display the actual lifting weight of the crane, rated lifting weight, lifting height, working range, jib angle, load rate and other operating parameters;

　　◆ The software interface is easy to operate, full button parameter setting and debugging, button debounce, the hardware has overvoltage and short circuit protection functions, and the system runs stably;

　　◆ It can input 1-4 force sensors for displaying and monitoring weight signals, 1 angle sensor for displaying and monitoring working amplitude or boom angle signals, and can also be connected to a photoelectric encoder for displaying and monitoring lifting height signals.

　　◆ According to user needs, it can record and count the crane's operation volume, and can be equipped with a micro-printer, RS485 communication interface, and provide weight data analog signal output.

　　◆ When the lifting capacity reaches 90% and 100% of the rated value, the sound and light alarm and output the overload control signal when the overload (105%~ 110%), the sound and light alarm and output the amplitude control signal when the amplitude exceeds the limit. According to the operation needs of the crane, multiple control signals such as loose rope and high and low speed switching can be provided;

　　◆ Applicable to track crane, bank bridge, gantry crane, floating crane, tire crane, car crane and other lifting equipment overload, overtorque control protection.
