Worker Under Suspended Load Monitoring
Mitigating Overhead Load Hazards with Suspended Load Monitoring for Dynamic Work Environments
Whether it’s a suspended beam or shifting load, viAct video analytics monitors worker under suspended loads in hazardous lifting zones or crane hoisting operations. With proximity alerts and real-time zone monitoring, it helps safety teams create a more controlled, incident-free environment during lifting-related activities.
Worker Under Suspended Load Monitoring is an advanced AI-driven safety solution designed to detect and prevent one of the most critical jobsite hazards, workers operating beneath active lifts or suspended loads. On dynamic worksites where cranes, hoists, or forklifts are in operation, the risk of injury from falling objects or swinging loads remains high, especially when physical exclusion zones are not properly marked or monitored in real time.
Using viAct proprietary video analytics, the system continuously observes designated lift paths and load zones through existing CCTV or IP camera infrastructure. It instantly detects when a worker enters a high-risk area beneath a suspended load, triggering immediate alerts to safety personnel.
This automated process reduces reliance on manual spotters, enhances visibility in blind zones, and enforces no-touch and DROPS (Dropped Object Prevention Scheme) safety protocols without delay. With continuous surveillance, historical event tracking, and seamless integration; worker under suspended load monitoring empowers EHS teams to reduce near-misses, promote safe lifting practices, and build a proactive safety culture.
What are the Risks if Workers Under Suspended Load are not monitored?
Worker under suspended loads (WUSL) remains a serious yet often overlooked hazard across industries like construction, logistics, manufacturing, and ports. These operations involve the movement of heavy materials using cranes, hoists, or forklifts—often in fast-paced environments where workers and machinery operate side by side. It’s not a lack of protocols, but the challenge of real-time enforcement that makes WUSL so dangerous. The load is mobile, workers are mobile, and visibility is often obstructed.
Common suspended load safety lapses include:
● Workers standing beneath or passing through active lifting zones
● Poorly marked or unenforced exclusion zones around cranes and hoists
● Reliance on manual spotters with limited visibility or delayed response
● Sudden load swings or drops due to wind, imbalance, or operator error
● Lack of situational awareness during shift changes or in congested areas
● Communication lags between crane operators and ground personnel
● Visual blind spots in tight, complex layouts
● No real-time alerts when personnel enter unsafe zones
What begins as a routine lift can become life-threatening when a worker unknowingly enters a danger zone. Even with strict SOPs and training, EHS teams can’t monitor everything at once. Suspended loads don’t wait for audits—they demand active, intelligent oversight.
Woker under suspended load monitoring fills this critical gap between safety planning and real-time prevention.
Where Is Worker Under Suspended Load Monitoring Needed Most?
Suspended load hazards often happen in dynamic environments with poor visibility, inconsistent supervision, or high human-machine interaction. viAct computer vision-powered Worker Under Suspended Load Monitoring module helps detect such scenarios.
Construction Sites with Cranes, Hoists or Rebar Lifting
Construction sites involve crane lifts, hoist movements, and suspended rebar cages. Workers passing through these zones can unintentionally walk beneath suspended materials during concrete pours or steel placements. viAct system monitors the lift path and instantly alerts supervisors of breaches into defined exclusion zone.
Manufacturing Floors & Warehouses with Overhead Material Handling
In fast-paced warehouse dispatch zones or manufacturing lines, overhead lifts often occur alongside human movement during loading, inspections, or urgent repairs. Workers may unknowingly enter active lift paths. The Worker Under Suspended Load Monitoring module flags high-risk overlaps early.
Lifting Casing, Modules in Rigs & Refineries
Offshore rigs often lift casings, risers, and subsea equipment over confined walkways, while refineries handle heavy modules during shutdowns in tight, high-traffic zones. Limited visibility and overlapping tasks heighten the risk of workers entering danger zones where the module provides real-time detection.
Mining Operations During Maintenance or Lift-Assists
During mining equipment maintenance, large components are lifted using cranes or hydraulic jacks, often in cramped or low-visibility areas. Workers assisting nearby may unknowingly enter danger zones. The worker under suspended load monitoring module detects such proximity risks before incidents occur.
Ports During Container Loading or Lifting Operations
In shipyards, massive containers are routinely lifted over decks and dock areas. Workers often operate in close proximity to these lifts. The AI detects real-time violations where workers enter under-the-load danger zones and provides alerts, helping suspended load safety high-traffic areas.
How is video analytics used to monitor Worker Under Suspended Load?
1
Choose
Select the “Worker Under Suspended Load Monitoring” module from viAct AI-powered solution hub. Specifically built to detect and monitor lifting zones, it helps ensure worker safety around overhead cranes, hoists, and suspended loads reducing risks in dynamic and high-traffic environments.
2
Connect
No need to install new cameras. The AI connects directly to your existing CCTV or IP camera system through RTSP. Setup is quick, simple, and doesn’t interrupt site activity.
3
Capture
The moment it’s live, the system starts watching key lifting areas—like crane paths, hook zones, and restricted spaces—24/7. It can detect:
● When someone walks under a suspended load
● If a worker stands too close to an active lift
● Any entry into clearly defined no-go zones with hanging loads
4
Control
When a violation is detected, the system triggers instant alerts: onsite through alarms or lights, and remotely through app, SMS, or the viAct dashboard. EHS teams can access all incidents, reports, and trends in one place helping them take swift action, fine-tune safety practices, and prevent repeat incidents.
Case Study: U.S. Manufacturing Plant Reduces Suspended Load Hazards by 82% with AI Monitoring by viAct

USA

Worker Under Suspended Load Monitoring
The Problem:
In a heavy equipment manufacturing plant, the fabrication bay used overhead cranes to lift large gear housings from CNC beds to assembly stations. During busy production hours and shift overlaps, workers frequently moved between zones—sometimes stepping into active lift areas while loads were suspended mid-air. Despite barricades and signage, these near-miss incidents became a growing concern for safety teams and violated both OSHA 1926 Subpart N and DROPS best practices.
The Solution:
To address recurring near-misses, the plant activated the Worker Under Suspended Load Monitoring module through its existing camera network. It quickly flagged unsafe proximity during lifts. “The system sees patterns we miss in the moment,” noted the safety supervisor.
The viAct impAct:
● Achieved an 82% reduction in unsafe entries under suspended loads within three months driven by proactive alerts and improved worker awareness about “10-foot rule” for suspended load.
● Enhanced alignment with OSHA and DROPS protocols while giving EHS managers real-time visibility to analyze, predict, and influence behavior around lifts without the need for additional hardware.
