For road and bridge construction, bridge erecting machine is the necessary equipment for bridge construction. With the rapid development of China's transportation industry and the continuous advancement of road and bridge construction, the application of bridge erecting machine is becoming more and more extensive, and its safety problems have also received more attention. As a large-scale and strong private enterprise in the field of road and bridge crane equipment, Tieshan crane has always attached importance to safety and regarded safety as the core goal of R & D and design.

Remember every aspect of safety. Turn uncontrollable to controllable

In the process of research and development and design of bridge erecting machine, the research and development designers of Tieshan crane will analyze the unsafe factors that may exist in the actual construction of bridge erecting machine and find a solution. After adjusting the design scheme, modeling analysis and testing are carried out through the software system to determine the safety and reliability of its design and the adaptability of the technology of this type of bridge erecting machine to the bridge design function. In the process of purchasing and producing raw materials and spare parts, quality inspectors will strictly check the raw materials and spare parts, and double quality inspection will ensure the quality and safety of each link of the product.

In addition to improving product quality in the design and production process, designing safety protection functions, and reducing the possibility of safety accidents, the standardized operation of construction personnel and the routine maintenance of equipment are also an important part of safety assurance. Because human factors are uncontrollable, over the years, the safety accidents of bridge erecting machines often occur, each with huge losses.

Case1：

In 2000, a bridge erecting machine collapsed on Shenyan Line. The ballast trough tray on the outer side of the extension curve supported by No.0 column suddenly collapsed, resulting in a major accident of 3 deaths, 1 serious injury and 4 minor injuries. The bridge erecting machine was seriously damaged and 1 24m curved beam was scrapped.

There are three reasons for the accident: one isThe technical performance of JQ130 bridge erecting machine is not suitable for the design function of T-shaped abutment. Second, the technical disclosure is unclear and the responsibility is unclear. Third, the laying personnel failed to fully understand the requirements of the "Frame Regulations.

Case2:

On the morning of July 19, 2012, when the construction site bridge of Hanjiatunte Bridge in Lintong District of Xi'an City was under construction, the bridge erecting machine tilted and fell, folded into an X-shape, and the ends of the extension arms on both sides were severely bent. The accident resulted in one death and one injury.

Cause of the accident: power failure occurred at the construction site. As there was no backup power supply installed, the equipment was immediately shut down. A side shift followed, and soon after an accident occurred, the equipment fell off the pier.

Suppress risk Make bridges safer.

In order to ensure the safe operation of the bridge erecting machine, Tieshan Lifting has developed aBridge machine safety monitoring platform, to achieve the bridge machine operation full dynamic real-time monitoring, for the road and bridge engineering construction safety."Double insurance". The safety monitoring platform includes risk alarm data and video monitoring. From the perspective of safety management, it can record the running time of each crane in more detail and provide more accurate data for maintenance work.

In addition, through the safety monitoring platform of the bridge erecting machine, the quality inspection workers can check the construction details and main mechanical components in real time, such as the jacking distance of the front and middle leg cylinders, the direction and speed of the winches and the front and rear vehicles. If the traveling speed is too fast, the risk of inertia imbalance may occur. By displaying the operation of the platform, the on-site operators can be prompted to further protect the construction safety.

One step closer, Tieshan Lifting will continue to move forward, helping the transportation industry and road and bridge engineering builders to implement the safety precautions of bridge erecting machines, and effectively ensure the safety of bridge erecting machines, construction personnel, and the construction environment.
