Fourobot's 48v descent controller (Model YSD-02) delivers enterprise-grade performance with a maximum load capacity of 50kg and dual-speed operation at 20m/min for both releasing and retracting. This compact 3.4kg unit manages up to 30 meters of cable with precision electronic control, featuring multiple communication interfaces (Ethernet, CAN, SBUS, PWM) and quick-release installation in just 3 seconds. With stable operation from -10°C to 40°C and intelligent ground-detection auto-unhook technology, it's engineered for industrial material handling, automated delivery systems, and controlled lowering applications where safety and repeatability matter most.

You're not just getting a controller. You're investing in a solution built on 10 years of manufacturing expertise. Our 48v descent controller system uses lightweight yet high-hardness materials that withstand demanding environments. The bottom-touch placement feature ensures your equipment knows exactly when it reaches ground level, automatically releasing the counterweight tray when it detects contact.
Remote operation gives you flexibility. Control your descent from a distance using our screen-equipped remote, virtual buttons, or the counterweight block itself. Installation takes seconds, not minutes, thanks to the intelligent quick-release module design.
