What Is Emergency Reverse Button on Electric Pallet Trucks?

From “Reversing Blind Spot” to “Automatic Protection” – An Invisible Safety Guard

In warehouse operations, reversing is one of the most common and most dangerous maneuvers. The operator‘s view is often blocked by the load, making it difficult to judge conditions behind — racks, pallets, other vehicles, or even colleagues may appear in the reversing path.

To address this safety hazard, Electric Pallet Trucks are equipped with a critical safety device: the Emergency Reverse Button. This article provides a detailed explanation of this button‘s function, trigger mechanism, usage scenarios, and its core value in safe operation.

1. What Is the Emergency Reverse Button?

The emergency reverse button is a safety touch device installed at the end of the control handle (or below it) on electric pallet trucks, specifically designed for collision prevention during reversing. In simple terms:

1. When reversing: If the button contacts any obstacle (cargo, racks, personnel), the truck immediately stops and automatically reverses a short distance

2. Essentially an “electronic safety wall”: Acts as a “third eye” when the operator‘s field of view is limited

This feature is explicitly required under EN 1175:2020 Safety of industrial trucks - Electrical/electronic requirements and has become an industry standard.

2. Working Principle: How Does It “Defuse” Danger in Milliseconds?

The emergency reverse button may look like a simple physical button, but it is actually a complete mechatronic safety system:

Trigger logic (typical timing) :

1. Contact detection: Button is pushed by an obstacle (pressure > threshold)

2. Signal processing (<50ms) : Controller confirms the signal

3. Reverse execution (<100ms) : Motor reverses, truck moves backward approximately 20-30cm

4. Automatic recovery: After the operator adjusts direction and the button resets, normal operation resumes

The entire process completes within 0.1-0.2 seconds — far faster than human reaction time (approximately 0.5-1 second).

3. Critical Role: Not Just “Reverse Collision Prevention” but “Personnel Protection”

Among warehouse accident statistics, reversing collisions account for as high as 27%, with approximately 40% involving personal injury.

The emergency reverse button provides:

Active protection: Does not require operator action — it is a “passively triggered” safety device

Mandatory collision prevention: Regardless of whether the operator checks the surroundings before reversing, the system intervenes automatically

Secondary accident prevention: The automatic reverse function prevents repeated collisions

Regulatory trend: The 2026 edition of ISO 3691-5 further strengthens automatic reverse braking requirements, making the emergency reverse button a standard safety feature on electric pallet trucks.

4. CBDE‘s Emergency Reverse Button Configuration

Take Diding Lift‘s 2T Stand On Pallet Truck Off Road CBDE as an example. This Electric Pallet Truck comes with the emergency reverse button as a standard safety feature.

The CBDE‘s built-in charger and optional lithium battery upgrade work in concert with safety features, ensuring the safety device remains available during charging and maintenance.

5. Usage and Maintenance Precautions

6. Summary

The emergency reverse button may appear to be a minor component on an electric pallet truck, but it is actually a critical safety line of defense. It can intervene automatically within milliseconds, compensating for the operator‘s limited visibility during reversing and significantly reducing the risk of reversing collisions.

For warehouse managers, confirming that the emergency reverse button is fully functional and reliable during equipment selection is essential. The system integrated into the CBDE reflects Diding Lift‘s commitment to safety design.
