Forklift Reverse Proximity Alarm with Radar

Forklift Reverse Proximity Alarm with Radar

The SF-431 Forklift Reverse Proximity Alarm is a radar-based safety system designed to reduce collision risks during forklift reversing.
By continuously detecting people, vehicles, and objects behind the forklift, the system provides clear audible and visual warnings and can automatically limit reverse speed when danger is detected.

How the Forklift Reverse Proximity Alarm Works

Using high-precision radar sensors, the system monitors obstacle distance and relative speed in real time.
When a person or object enters the detection area, the forklift reverse proximity alarm activates graded alerts and safety actions based on distance.

Dual Safety Zones for Collision Prevention

Warning Zone

• Audible and visual alarm when an obstacle is detected

• Real-time distance shown on the display

• Optional automatic speed limiting to ≤3 km/h

Braking Zone

• Strong audible alarm with voice distance prompts

• “Stop” voice alert when distance is below 30 cm

• Automatic stop in reverse mode (with throttle control)

• Forklift resumes movement only after switching to forward gear
  

Speed Monitoring & Overspeed Alerts

• Three-level speed alarm with different voice prompts

• Overspeed audible and visual warnings

• Supports both electronic and mechanical throttle control
  

Key Benefits

• Enhanced forklift reverse safety in blind-spot areas

• Radar-based detection unaffected by dust or lighting

• Automatic speed limiting to reduce human reaction errors

• Wide compatibility with different forklift models

• Stable operation with strong anti-interference performance
  

Applications

• Warehouse reversing lanes

• Narrow aisles and loading docks

• High pedestrian traffic zones

• Low-visibility or noisy industrial environments
  

This forklift reverse safety system is ideal for warehouses, factories, and logistics sites where blind spots and pedestrian interaction create high accident risks.
For sites requiring a higher level of pedestrian protection and full-area monitoring, you may also consider our AI-Based Collision Avoidance Systems,which use AI vision to detect and prevent collisions beyond reverse-only scenarios.
