China Tower Crane Safety Operation Collision Avoidance System Appraisal

The "tower crane cluster safety operation intelligent control system" independently developed by the Wuhan Special Equipment Supervision and Inspection Institute has passed the national scientific and technological achievements appraisal. The overall technology of collision prevention is at the leading domestic level, and some technologies have reached the international advanced level.

With the rapid development of economic construction, the number of large-scale tower cranes widely used in various types of construction projects has increased, and the density of deployment has increased. In recent years, collisions have occurred between tower cranes, collisions between tower cranes and surrounding buildings, and other safety incidents. As a result, the development of a tower crane safety operation collision avoidance system has been stepped up to become a scientific and technological project that guarantees safe production and strengthens scientific supervision to fill gaps.

The core tower technology is composed of implanted hardware equipment and professional analysis and management software, including tower crane collision avoidance warning device and tower crane operation network monitoring. It is included in the AQSIQ Science and Technology Plan project's "Tower Crane Cluster Security Operations Intelligent Control System". Platforms, etc. The network-based monitoring platform provided by the intelligent control system realizes remote monitoring of the tower crane's working site and operating dynamics.

According to reports, the tower crane collision avoidance warning device is an integrated electronic system used to prevent tower cranes and tower cranes, tower cranes and fixed obstacles, tower cranes and high-voltage lines from colliding with each other, and to prevent tower cranes from intruding illegally into illegal areas. Tower Crane Operation Network Monitoring Platform is to realize the real-time monitoring of the record management, operator management, and operation status (angle, amplitude, height, hoisting weight, torque, wind speed, alarm status, etc.) of all tower cranes in use in an area.

At present, national standards for tower cranes clearly require the installation of alarms and display recording devices and working space limiters, while the National Ministry of Housing and Urban-Rural Development also requires that large-scale lifting appliances must be equipped with a safety monitoring and management system. In this regard, some major cities in China have successively issued safety production policies that require that tower cranes be equipped with anti-collision devices and safety monitoring systems to ensure the safe operation and social safety of tower cranes.

"Tower Crane Cluster Safety Operational Intelligent Control System" was used in a number of construction projects in Wuhan since October 2011. After continuous debugging and gradual improvement, the system has been operating stably with good anti-jamming performance and all technologies have been met. The engineering construction unit reflected that they effectively prevented the collision between the tower crane and the tower crane, between the tower crane and the fixed obstacle, and between the tower crane and the high-voltage line when the multi-tower cranes cooperated in complex environments.

Entrusted by the AQSIQ, the appraisal committee conducted an item-by-item inspection and test of the data collection, information transmission, and intelligent control of the “tower crane cluster safety operation intelligent control system”, and passed the appraisal of the science and technology project. Experts believe that this innovative achievement with independent intellectual property rights is characterized by safety and reliability, complete functions, high degree of automation, and easy operation, and can meet the safety requirements of tower crane cluster operations.
