How Mecha PELV Make Workers Normally on Foot Easier to See in a Mecha PELV
Workers Are Invisible to Heavy Equipment
Mecha PELV makes workers normally on foot visible early enough for heavy industrial vehicles to stop.

System: Elevates Workers for Visibility

Mecha PELV elevates workers above blind zones, increasing line-of-sight and early detection by operators.
- Elevates worker into visible range
- Expands visual profile
- 36" light bar ensures persistent detection
Users: On-Foot Worksite Personnel

Designed for workers most exposed to heavy equipment risk:
- Laborers and ground crews
- Supervisors and foremen
- Engineers, inspectors, and surveyors
Risk: Equipment Operators Can’t Necessarily See Workers on Foot Standing Around

Operators cannot see workers in critical zones due to blind spots, machine structure, and jobsite conditions.
- Visibility is limited by physics
- Workers assume visibility incorrectly
- Detection often occurs too late to react
This is a system failure, not a training failure.
Function: Prevents Struck-By Incidents

Mecha PELV increases detection distance so operators can stop in time.
- Typical detection (on foot): 20–40 ft
- Stopping distance: 60–100+ ft
- Mecha detection: 80–150+ ft
Creates positive stopping margin.
Deployment: Ready for Job Sites

Deploy immediately across active environments:
- Construction sites
- Road work zones
- Energy and industrial projects
Minimal setup. Short certification. Immediate impact.
Schedule Pilot DeploymentJustification: Safety Data

Struck-by incidents are a leading cause of workplace injury and death.
- Nearly half involve vehicles or equipment
- Billions in annual costs
- High incidence in construction and work zones

Operators consistently identify visibility as the primary risk factor.
6x Visibility: Visibility Science

Visibility improves through combined factors:
- Elevation increases line-of-sight
- Structure increases visual profile
- Light increases detection distance
These combine to produce a multi-factor visibility advantage.
Saving Lives: ROI
- Average injury cost: $40,000+
- Fatality cost: $500K–$1M+
- Indirect costs significantly higher
Preventing one incident justifies deployment.
Academy: Training & Certification
Short certification ensures safe and effective use:
- Operational training
- Visibility protocols
- Worksite integration
Comparable to vehicle or light equipment training.
