This "three-in-one" visual safety system for tower cranes utilizes a modular industrial platform design and features an 11.6-inch 1080P IPS display unit that monitors load, moment percentage, weight, anti-collision status, working radius, height, tilt angle, and wind speed in real time. It integrates a hook-tracking camera, a 360° panoramic imaging system, in-cab facial recognition, and millimeter-wave radar. The system employs wireless bridge transmission technology (ensuring zero latency), boasts an IP67 protection rating, and operates within a temperature range of -30°C to +70°C. It comes equipped with magnetic sensors (allowing for installation without cutting), a wired mouse, and a 12V in-cab power adapter. Comprehensive technical documentation is provided to meet the requirements for special equipment inspections and "smart construction site" acceptance standards.

Project experience

A crane rental company from South Korea came to China to source crane components and met Shandong Zhinuo at a trade show. The question they brought was not about price or lead time — it was about what happens when several tower cranes work the same airspace. What followed was a proposal, three visits to China, and a machine the client arranged himself so the equipment could be fitted and tested on it.

A UK client's custom tower crane needed a safety system built around it, not bolted onto it. ZNAQ developed the package under the crane factory's requirements, and both engineering teams confirmed mounting, calibration and alarm logic on site.
