With the rapid advancement of intelligent technologies, the construction machinery industry has achieved a major breakthrough. On March 28, 2025, Qingdao Haiyuehui Technology Co., Ltd. officially launched its unmanned remote-controlled excavator. Featuring innovative technologies such as 300-meter ultra-long remote control, real-time image transmission, and electromagnetic absorption devices, it redefines the standards of safety, efficiency, and precision in construction operations. This solution is designed for high-risk scenarios including mining, unexploded ordnance disposal, and emergency rescue.

Ultra-long-range operation for enhanced safety
Conventional excavators often operate in hazardous environments with
risks like collapses and explosions. However, Haiyuehui's unmanned
remote-controlled excavator enables 300-meter ultra-long-distance
operation, allowing precise control from safe zones to eliminate
personnel risks. Its military-grade anti-interference communication
system ensures stable signals in complex environments, significantly
enhancing reliability under extreme working conditions.
