Large LED screens are everywhere, but LED engineering projects almost every year have some big or small "accidents". This year, serious injuries occurred. At the end of July, the Hong Kong Red Mansion LED screen fell down and injured people. Hong Kong Top Idol Group Mirror held a concert in the Red Mansion, and a large LED screen hanging above the stage suddenly fell and hit the two dancers who were performing! Both actors suffered spinal injuries to varying degrees. One was relatively stable, while the other was seriously injured. When they were sent to the hospital, they were in a tertiary coma and are still recovering. This accident has aroused great concern both inside and outside the industry.
In August, the accident investigation team published the results, believing that the wire rope that fell off the big screen that night was broken due to "metal fatigue". Preliminary investigation showed that one of the wire ropes hanging the LED screen was broken, and the eyebolt of the other wire rope was broken, causing the screen to fall.
On November 11, the Hong Kong police disclosed the details of the Hong Kong Red Mansion screen falling accident. The investigation found that the general contractor "Yineng Engineering Co., Ltd." (hereinafter referred to as "Yineng") in charge of the concert project and "Xiexinglong Stage Engineering Co., Ltd." (hereinafter referred to as "Xiexinglong") in charge of the stage project did not take any measures to ensure that the stage equipment reached a certain safety and quality level; The former is also suspected of falsely reporting the actual weight of the device in order to obtain performance permission as soon as possible. Five people related to the construction of the project were arrested for "fraud" and "allowing objects to fall from heights".
The Hong Kong police said that "Yineng", as the general contractor, has absolute control over the stage and is also responsible for ensuring the safety of the installation. The LED screen of the accident was installed and operated by "Xiexinglong". The Hong Kong police found that there was no evidence that "Yineng" and "Xiexinglong" had taken any measures to ensure that the mechanical parts and devices reached a certain level of safety and quality and could be used safely.
According to the report, the Hong Kong police also found that after the installation of the lifting device was completed, no qualified engineer was assigned to conduct a detailed inspection to ensure that the lifting device can operate safely; On the morning of the incident, there was a problem with the lifting of the screen. At that time, the staff of "Xiexinglong" had made adjustments, but they did not report to anyone, nor did they take further maintenance and remedial measures.
In fact, during the construction of LED large screen, there are many collapse accidents of large screen caused by improper construction, unreasonable structure and other factors in recent years. These safety accidents are worth thinking deeply in the industry. If we have a responsible professional project manager and senior technicians with certificates to strictly control each pass during the project construction, perhaps the relevant safety accidents will not occur.
The industry is developing rapidly and there is a large talent gap for professional projects
LED display enterprises in China have installed countless large LED screens for the world over the years. Nowadays, various screens inside and outside the home are getting larger and larger, and many of them have reached the replacement cycle. The demand for relevant businesses and operators is also increasing, but there is a large gap for qualified business directors, project managers, technical coordinators and senior technical construction personnel. During the construction process of many projects, due to the lack of qualified personnel, some hidden safety hazards cannot be eliminated in time. Even if some projects are equipped with relevant personnel, there is a fluke mentality or their own professional quality is not high, The accident will eventually occur.
LED display works mainly focus on steel frame design, erection, screen stacking, hoisting, etc. Some outdoor works are also closely related to building and civil engineering. Relevant project managers and technicians must have professional professional quality. Such talents are not simply used in construction sites. For this reason, relevant national departments are also constantly strengthening and standardizing the construction safety system in subdivisions, including LED project construction, and increasing the training of professional project talents. Of course, relevant LED manufacturers, general contractors and construction parties should pay more attention to this and eliminate potential safety hazards.
