<\/p>\nCrane overturning accidents have always been one of the deadliest safety threats in the industry on construction sites, ports and wind power construction sites. According to statistics, in 2022, there will be a total of 37 major lifting machinery accidents across the country, of which capsizing accidents accounted for as high as 43%, causing direct economic losses of more than hundreds of millions of yuan. As the key technical equipment to meet this challenge, the crane anti-overturning system has become the core link of multiple safety guarantees from national standards to industry practices. Through intelligent perception, real-time analysis and automatic intervention, this system has built a digital security line of defense for lifting equipment.<\/p>\n
<\/p>\n
The core of modern anti-overturning systems is like equipping cranes with an \u201dintelligent balance brain\u201d. The system collects more than 15 safety parameters in real time, including outrigger pressure, levelness, wind speed and moment percentage, through a sensor network distributed at key parts of the crane. These data are transmitted to the central processing unit via Internet of Things technology and analyzed at the millisecond level by specially developed security algorithms. When a dangerous working condition is detected, the system will activate a three-level response mechanism: first, it will issue an audible and visual warning to alert the operator, then automatically limit the amplitude of the dangerous operation, and finally directly cut off the dangerous operation in an emergency. Take the WTF series anti-overturning system developed by Weite Technology as an example. It adopts military-grade MEMS tilt sensors, with a levelness monitoring accuracy of 0.1 degrees and a torque protection response time of no more than 0.2 seconds, far exceeding the national standard requirements.<\/p>\n
The anti-overturning systems of different lifting equipment have their own focus. Tower cranes mainly rely on the dual protection of tilt monitoring and torque restriction of the tower body, paying special attention to the risks caused by foundation settlement; truck cranes focus on the pressure balance of the outriggers and the level of the whole machine, because most truck crane overturning accidents are caused by unstable support of the outriggers; gantry cranes due to the complex operating space,Anti-collision and regional restriction functions need to be increased; and wind power installation cranes need to specifically consider the impact of mountain terrain and sudden wind and weather. Records of a wind power project of a central enterprise show that the anti-overturning system installed by it successfully warned of the risk of overturning caused by mountain wind gusts 17 times in one year, avoiding possible major accidents.<\/p>\n
The installation quality of the anti-overturning system is directly related to the protective effect. Before installation, the equipment structure must be evaluated by a professional institution to determine the optimal placement of the sensors. Level sensors are usually installed at the position of slewing bearings and need to be particularly kept away from vibration sources and high-temperature areas. When installing the outrigger pressure sensor, it is necessary to ensure that the force-bearing surface is flat and in contact. System debugging requires precise calibration on the calibration platform. It is recommended to conduct professional calibration once every six months. Daily maintenance requires the establishment of a \u201ddaily inspection - weekly calibration - monthly verification\u201d system: operators check daily whether the display device is functioning properly. The safety officer tests the effectiveness of the early warning function every week. The equipment department checks the completeness of data records every month. Statistics from a certain port group show that for equipment that adheres to standardized maintenance, the false alarm rate of the system has decreased by 80%, and the reliability has significantly improved.<\/p>\n
The "Technical Regulations for the Safety of Lifting Machinery" (TSG 51-2023) issued by the State Administration for Market Supervision and Administration clearly stipulates that mobile cranes with a rated lifting weight greater than 50 tons and all tower cranes must be equipped with anti-overturning safety protection systems. The system must include three basic functions of level monitoring, torque limiting and wind speed alarm, and the data recording device should be able to continuously store operating data for at least 30 days. In addition, the national standard GB\/T 3811-2008 "Crane Design Specifications" also specifies the system performance indicators in detail: the level alarm error is not greater than 0.5 degrees, and the torque protection error does not exceed 5%. The newly revised specifications in 2023 have added system self-diagnosis and remote monitoring requirements, reflecting the new direction of industry development.<\/p>\n
Common faults are mainly concentrated in three major areas: sensor drift, signal transmission interruption, and power fluctuation. The zero drift of the level sensor is the most common problem, which can be solved by recalibrating the standard level platform; signal interference is mostly caused by improper wiring, and shielded cables and separate pipes should be used for laying; power fluctuations need to be equipped with online UPS power supply. When the system issues an alarm, the operator should immediately stop the dangerous operation, but should not blindly turn off the system power-an accident occurred on a construction site last year due to the operator mistakenly turning off the alarm system. It is recommended to establish a clear emergency response process: first stop the operation\u2192 then analyze the cause of the alarm\u2192after eliminating hidden dangers\u2192reset the system according to regulations. The system should also be equipped with an emergency protection unit independent of the main system to ensure that basic protection can still be provided in the event of a failure of the main system.<\/p>\n
There are three key dimensions to consider when choosing an anti-overturning system: technical performance, adaptability, and service support. In terms of technology, the focus is on sensor accuracy (level of at least 0.1\u00b0), protection level (IP67 or above) and certification qualifications (special equipment manufacturing license); adaptability should be checked whether to support your equipment model and interface protocol; service support depends on whether to provide localized technical support and regular calibration services. International brands such as Liebherr in Germany and Crane Pro in the United States have excellent performance but higher prices; domestic brands such as Weite WTF series and Sany SYMC have better price ratios and are more adapted to domestic working conditions. It is recommended to avoid choosing products from unqualified small factories. False positives have occurred frequently due to the installation of cheap systems in a logistics park, which seriously affects operational efficiency.<\/p>\n
The most dangerous working conditions in lifting operations often occur under extreme weather conditions. The modern anti-overturning system ensures reliability in harsh environments through multiple designs: the sensor adopts a wide-temperature design (-40\u2103 to +85\u2103), guaranteeing the ability to operate normally in extremely cold and hot conditions. The electrical system is equipped with lightning protection and overvoltage protection modules. The software algorithm adds a wind load compensation algorithm, which can distinguish the different influences of continuous wind and sudden gusts. It is particularly important that the system establish a hierarchical early warning mechanism - a level 6 wind alert, a level 7 wind limit the range of operations, and an level 8 wind automatically stop operations. In a certain offshore wind power project in the Bohai Bay, the anti-overturning system successfully withstood the test of Typhoon \u201dMinghua\u201d. When the wind speed reached the shutdown threshold, it automatically cut off the operation permission, avoiding possible equipment damage.<\/p>\n
With the development of intelligent sensing technology and 5G communication, the new generation of anti-overturning systems is evolving towards predictive protection. By analyzing the historical operation data of the equipment through big data, the system can predict potential risks and issue early warnings, truly achieving a leap from \u201dpassive protection\u201d to \u201dactive prevention\u201d. Choosing a reliable anti-overturning system is not only a compliance requirement but also an important guarantee for personnel safety, equipment protection and return on investment. It is recommended that equipment users consult professional institutions when purchasing, select the most suitable system configuration based on specific working conditions, and establish a complete usage and maintenance system to ensure that safety technology truly plays a protective and safeguarding role.<\/p>","protected":false},"excerpt":{"rendered":"
