Tower Crane Lifting Zone Alert: Ensuring Safety in High-Rise Construction

4 minutes, 7 seconds Read

High-rise construction projects are feats of engineering and architecture that redefine skylines and shape the future of cities. Tower cranes are integral to these endeavours, performing heavy lifting tasks with precision and efficiency. However, the operation of tower cranes presents unique safety challenges, especially in congested urban areas. To address these concerns, the construction industry has turned to advanced technology solutions like viAct’s viMAC, a Smart AI Monitoring system designed to enhance safety in tower crane lifting zones.

Understanding the Challenge: Tower Crane Lifting Zone Safety

The towering presence of a crane on a construction site symbolizes progress and ambition. Yet, this powerful machinery also poses significant risks. Tower crane lifting zones are busy hubs where multiple activities converge, and failure to manage them effectively can lead to accidents, injuries, and costly delays. Here are some of the primary safety challenges faced in these zones:

  • Limited Visibility & Blind Spots: Tower crane operators often have restricted sightlines, making it challenging to detect potential hazards or obstacles in real-time.
  • Communication Barriers: Coordinating actions between the crane operator, ground personnel, and other heavy machinery operators can be challenging, leading to miscommunications and errors.
  • Overload Risks: Lifting heavy loads demands precision, and exceeding a crane’s load capacity can have catastrophic consequences.
  • Weather Conditions: Adverse weather conditions like high winds can compromise crane stability, making it essential to monitor and adjust crane operations accordingly.

Introducing viMAC: viAct’s Smart AI Monitoring Solution for Tower Crane Lifting Zones

viAct, at the forefront of construction safety innovation, harnesses the power of Artificial Intelligence (AI) and video analytics to provide advanced workplace safety solutions. Its groundbreaking smart site safety system revolutionizes safety performance at jobsites, offering a comprehensive array of intelligent safety solutions. These solutions encompass everything from PPE detection and hazardous areas access control to work at height monitoring and tower crane lifting zone alerts.

One of the standout components of viAct’s safety arsenal is the AI monitoring solution for machineries known as viMAC. This ingenious system utilizes AI video analytics to enhance tower crane lifting zone safety in several ways:

  1. Worker’s Lifting Zone Intrusion Detection: The dynamic video surveillance system (VSS) can identify instances where workers enter the tower crane lifting zone. The moment this potential danger is detected, viMAC’s danger zone alert system springs into action, generating instant real-time alerts. These alerts are disseminated to the crane operator, on-site workers, and other relevant stakeholders. This rapid notification empowers them to take immediate corrective measures, thus mitigating the risk of accidents and fatalities.


  1. Tower Crane Operator’s Distraction Detection: Leveraging video analytics for workplace safety, viAct’s construction safety software has the capability to detect instances where the crane operator is not paying adequate attention or is distracted during crane operation. In response, the system activates light and sound alarms, effectively alerting the operator to refocus their attention and ensuring safer tower crane operations.


  1. Cargo Overweight Alert: In the event that the tower crane is loaded with an excess of weight or a load, the dynamic AI monitoring system is quick to recognize this condition and trigger an alert. This immediate notification allows for proactive measures to be taken, preventing incidents such as tower crane overturns or the dropping of heavy loads.


  1. Object Free Fall Alert: viMAC is a highly flexible, portable AI monitoring solution that excels at detecting objects or loads falling from the overhead crane. Upon identifying such a hazardous situation, the system triggers real-time alerts through its dangerous situation alert system. These alerts promptly inform all involved parties about the perilous circumstance. Furthermore, these critical insights are meticulously recorded within the centralized management platform for construction. This valuable data can then be reviewed and utilized for worker training and continuous safety improvement.


  1. Worker-Object-Machine Collision Detection: Equipped with computer vision-powered cameras, the video surveillance system excels in detecting situations where workers are positioned too close to the operating tower crane or where the crane is operating dangerously close to structures or objects. viMAC promptly triggers alerts to avert potential collision accidents, thereby ensuring the safety of both workers and equipment.


In addition to the aforementioned capabilities, viAct’s intelligent AI monitoring solution is adept at identifying mechanical errors such as brake failures and instances of objects narrowly avoiding collisions. This comprehensive approach to safety ensures the holistic well-being of tower crane operations, reducing the likelihood of accidents and incidents. With viMAC, viAct continues to lead the way in making construction sites safer and more efficient through the power of AI technology.


Thus, as high-rise construction projects continue to shape our urban landscapes, it is imperative that we prioritize safety in tower crane lifting zones. viAct’s viMAC represents a leap forward in achieving this goal, using smart AI monitoring to enhance communication, predict potential hazards, and provide real-time data for better decision-making. With viMAC, the construction industry can build not only taller structures but also safer ones, ensuring a brighter and safer future for our cities.
