JSL-D1 type lifting torque (overload) limiter

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

　　◆ The instrument panel is made of heat-resistant materials imported from Germany, which is durable.

　　◆ Adopting 5.7-inch LCD touch screen display, it can display the actual lifting capacity, rated lifting capacity, lifting height, working range, boom angle, load rate and other operating parameters of the crane according to working conditions (such as main hook/auxiliary hook, hook/grab, etc.), and can also display 4-way single rope lifting weight at the same time.

　　◆ Chinese and English display interface, operation prompt function, simple and convenient debugging, 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 photoelectric encoders or length measuring instruments, etc.;

　　◆ According to user needs, it can record and count the crane's operation volume, and can be equipped with a micro printer, RS232/485 communication interface, and provide weight data analog output.

　　◆ When the lifting capacity reaches 90% and 100% of the rated value, sound and light warning; when the overload (105%~ 110%), sound and light alarm and output overload control signal; when the amplitude exceeds the limit, sound and light alarm and output amplitude control signal. 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, automobile crane, marine crane and other lifting equipment overload, overtorque control protection.
