【HANKUN Truck Mount VMS】135° Fold Redefines Rescue Safety – Why 45° More Makes All the Difference

1. Problem at the Core: The 90° Limitation Failure

Traditional truck-mounted VMS with 90° folding fail catastrophically during rescue operations:

When a rescue truck’s bed tilts 45° to load a vehicle, the 90°-fixed screen angles 135° toward the ground, creating a 35° blind spot for following drivers (outside the 25° effective human visual range).

This leads to a 60% drop in message recognition rate, increasing secondary accident risk by 27% (FHWA data).

2. The 135° Solution: Engineering for Real-World Rescue Dynamics

HANKUN’s breakthrough design adds a 45° dynamic compensation axis to the traditional 90° base fold:

Dual-Axis Mechanism:

90° Base Fold: For compact transport (1.8m height).

45° Electric Push Rod: Activates when the truck bed tilts, adjusting the screen to 110° toward traffic (eliminating the blind spot).

Smart Calibration: IMU sensors and AI algorithms continuously monitor the truck bed angle, ensuring the screen’s normal line stays within ±20° of the traffic flow – the optimal range for quick driver recognition.

Conclusion: A Design Driven by Rescue Reality

The 135° fold isn’t just a feature – it’s a response to the critical need for visibility when lives are on the line. By merging mechanical precision with human factors engineering, HANKUN ensures every rescue scene benefits from technology that works as hard as the teams using it.
