Its Safety Monitoring System (also known as Black Box) displays the data of working radiuses, heights, moments and weights.

The use of world-famous electric components such as OMRON, YASKAWA, Schneider (TE) and MEAN WELL greatly reduces the failure rate of the electric control system and improves the work efficiency of the users.
