Underrun protections for tail gates and truck lift gates – Safety and compliance on the road

Underrun protections are essential safety components for vehicles equipped with a tail gate or lift gate. They not only protect the sensitive hydraulic and frame structures from damage but also prevent other vehicles from sliding underneath the rear of the truck in a collision. They are therefore crucial for road safety and compliance with regulations such as UNECE Regulation R58-03. For workshops, fleet operators, and private users, underrun protections are indispensable components that ensure safe operation, long service life, and regulatory compliance of the tail gate or lift gate. Combined with high-quality tail gate and lift gate spare parts, they increase overall reliability and system efficiency.

Function and design of underrun protections for tail gates and lift gates

An underrun protection is firmly mounted below the tail gate or lift gate at the rear of the truck, forming the last safety barrier between the vehicle and following traffic. Its main purpose is to prevent smaller vehicles from sliding under the truck in a rear-end collision. This protection is particularly important for lift gates, where the platform or lifting mechanism sits below the frame edge. Technically, underrun protections are made of high-strength steel or corrosion-resistant aluminum alloys. They are designed to absorb impact energy without restricting the movement or load capacity of the tail gate. Precision mounting and certified welds ensure maximum stability and long-term durability in daily operation.

Types and configurations of underrun protections

Underrun protections are available in various configurations to meet the specific requirements of tail gates and lift gates. Most models are rigid bolted constructions made of high-strength steel or aluminum and meet UNECE R58 standards. Depending on the vehicle type, their shape, width, and mounting points vary to ensure perfect integration into the chassis and lift system. For practical applications, underrun protections can be equipped with integrated rear steps, anti-slip treads, or mounting points for lighting and license plate holders. These designs combine protection, functionality, and comfort in one robust structure – ideal for intensive transport and logistics operations.

Maintenance and inspection – For lasting safety and performance

Underrun protections are exposed to heavy loads during daily use: weather, road debris, and mechanical stress can cause corrosion or material fatigue. Therefore, regular inspection as part of tail gate or lift gate maintenance is essential. Visual checks for rust, cracks, or loose bolts should be part of every vehicle inspection. Damaged or worn components can be easily replaced with compatible tail gate or lift gate spare parts. Proper maintenance ensures that the underrun protection fully retains its safety function and preserves the long-term integrity of the entire lifting system.

Quality and safety standards for underrun protections on tail gates and lift gates

For underrun protections, quality is key – they directly determine safety and reliability in daily use. Only high-strength materials such as galvanized steel or aluminum and precise manufacturing according to current standards ensure dependable impact protection. Our underrun protections are developed and tested in accordance with UNECE R58 requirements. They are specifically designed for installation on tail gates and truck lift gates, combining stability with perfect fit. For workshops and fleet operators, this means certified products that not only meet legal safety requirements but also extend the lifespan of the entire lifting system – keeping your vehicle safe and technically protected at all times.

Key advantages of underrun protections for tail gates and lift gates

• Protection for tail gate and lift gate: Shields hydraulics, mechanics, and platform structures from external impact or collision damage.
• Durability through robust materials: High-strength steel or corrosion-resistant aluminum ensures stability and long service life.
• Easy maintenance and spare part supply: Clear design and available tail gate and lift gate spare parts enable quick servicing.
• Tailored fit for every vehicle type: Different widths, shapes, and mounting systems ensure perfect integration with tail gates and lift gates.

Frequently asked questions about underrun protections for tail gates and lift gates (FAQ)

Why are underrun protections important for tail gates and lift gates?

An underrun protection prevents smaller vehicles or pedestrians from sliding under the rear of a truck, protecting lives, reducing accident risks, and ensuring road safety – especially for vehicles equipped with tail gates or lift gates.

What materials are high-quality underrun protections made from?

They are typically made from high-strength steel or corrosion-resistant aluminum, providing maximum stability with minimal weight – ideal for demanding, long-term road use.

How often should underrun protections be serviced?

We recommend inspecting underrun protections during every tail gate or lift gate maintenance cycle. Visual checks for rust, cracks, or loose fasteners are essential. If wear or damage is detected, compatible spare parts should be used to restore full safety performance.

Are underrun protections compatible with all tail gates and lift gates?

Depending on the vehicle type and configuration, mounting points and dimensions vary. Therefore, underrun protections come in different versions designed for common tail gate and lift gate systems. Expert workshops provide consultation to ensure a perfect fit.

Where can I find suitable spare parts or retrofit solutions?

At specialist companies, you’ll find certified underrun protections as well as compatible spare parts for tail gates and lift gates. All components are designed for durability, compatibility, and maximum safety in daily use.
