DEVELON Series 9 excavators integrate AI to prevent jobsite collisions

As construction sites navigate increasing spatial constraints and complex traffic patterns, preventing pedestrian collisions remains the most critical safety challenge for heavy equipment operators. While traditional passive safety systems rely on alarms to warn the operator, the industry is shifting toward active intervention technologies capable of halting a machine autonomously before an impact occurs. DEVELON’s new Series 9 crawler excavators integrate artificial intelligence and radar to monitor these blind spots, offering a final layer of defense without disrupting site productivity.

From passive warning to active intervention
Traditional construction safety technology has heavily relied on passive systems—mirrors, basic reversing cameras, and proximity alarms—that present information and leave the operator to interpret the risk and execute a response. However, fatigue, poor weather conditions, and distraction can severely compromise an operator's reaction time over an eight-hour shift.

Drawing heavily from automotive blind-spot monitoring technologies, DEVELON has developed its E-Stop system to provide active mechanical intervention. When a hazard reaches a defined critical threshold, the system bypasses human reaction times and physically interrupts the machine's movement. While this does not replace operator judgment or established site exclusion zones, it acts as a failsafe to break the chain of events that leads to severe or fatal crushing incidents.

The E-Stop system in practice
The DEVELON E-Stop architecture relies on a multi-sensor fusion approach. Six high-definition cameras capture a continuous 360-degree view around the excavator, utilizing machine learning algorithms specifically trained to distinguish human pedestrians from static objects, vehicles, or debris. This visual data is cross-referenced by three radar sensors providing precise distance measurements across a 330-degree radius, mapping the principal blind-spot areas.

During extensive field testing with contractors in France, operators reported that the system successfully receded into the background during normal operations. By avoiding frequent false alerts and unnecessary cycle interruptions, the technology allows operators to maintain focus on the excavation task with the confidence that the machine will autonomously intervene only when an actual collision is imminent.

Integrating technology into fleet culture
The transition toward intelligent intervention is increasingly driven by large contractors and rental companies standardizing safety requirements across their fleets to reduce insurance exposure and support prequalification for complex projects. DEVELON has positioned its Smart All-Around View Monitoring (SAVM) system—including the AI-driven people recognition—as standard equipment on the Series 9 excavators. The active E-Stop intervention remains an optional upgrade requiring the additional radar sensor hardware and software integration. As these systems prove their reliability and cost-effectiveness in preventing severe accidents, active anti-collision technology is projected to become a standard jobsite specification over the next decade.

Additional Context: Multi-stage intervention and Virtual Walls
This section details technical specifications and operational mechanics not included in the original feature article.

The SAVM and E-Stop systems operate through a phased, three-stage intervention protocol with a maximum detection range of 6 meters. When the HD cameras visually detect a pedestrian entering the outer perimeter, the system issues a warning and automatically slows the excavator's hydraulic functions. If the individual breaches the 4-meter critical threshold, the system autonomously halts the machine's swing and reverse travel entirely. To further enhance site safety, the Series 9 interface features a "Virtual Wall" capability, allowing operators to digitally geo-fence the excavator's swing radius and boom height. This prevents the machine's physical structure from breaching predefined operational limits, mitigating the risk of striking adjacent buildings, live traffic lanes, or overhead power lines in highly confined urban work zones.
