Zero-Harm Plant Operations on Civil Worksites

Heavy excavators, compactors, and articulated trucks operate alongside ground workers every day. Eliminating blind-spot crush fatalities requires strict physical separation and positive communication.

1. 10-Metre Exclusion Radius

Erect physical barriers and signage maintaining a minimum 10m exclusion radius around excavators and heavy mobile plant.

2. Quick-Hitch Safety Pin Checks

Operators must conduct a ground-crowd test to verify that hydraulic quick-hitch safety locking pins are positively engaged before swinging any attachment.

3. Proximity Sensors & 360 Cameras

Fit modern plant with broadband 'squawker' white-noise alarms and AI pedestrian detection cameras to provide real-time cab alerts.
