Designed for heavy cargo.
The 3-axle mechanical steering flatbed is optimised for the most demanding logistics: precast concrete elements, structural steel, and oversized prefab loads that demand both capacity and maneuverability.
Concrete Elements
Precast concrete beams, columns, and wall panels loaded flat on the deck and secured with heavy-duty lashing points. The low deck height keeps centre of gravity manageable on site access roads.
Steel Beams & Long Loads
Long structural steel sections and oversized prefab components demand a trailer that tracks cleanly through roundabouts and narrow site entrances. The mechanical steering axle delivers exactly that.

Key Features
Every component chosen for durability, performance, and ease of operation — from the steering axle linkage to the last lashing point.
Steering System
The Steering Axle. Tight Turns Made Simple.
The mechanical steering rear axle follows the tractor automatically — no hydraulics, no operator input, no added complexity. Reduced swept path, reduced tyre wear, reduced site access problems.
Tighter Cornering
The mechanical steering axle significantly reduces the turning radius compared to a fixed-axle 3-axle flatbed — essential for delivery to tight urban construction sites.
Reduced Tyre Wear
Fixed rear axles scrub tyres aggressively in corners. The steering axle eliminates this — extending tyre life and lowering your operating cost per kilometre.
Chassis & Structure
I-Beam Backbone. Built to Endure.
ST52/S355J2+N welded I-beam main frame provides the longitudinal rigidity to carry concentrated point loads from concrete elements and structural steel without flex or fatigue.
Full Penetration Welding
Main frame joints are fully welded for maximum strength continuity. Crossmember spacing is calculated to distribute concentrated cargo loads evenly across the main beams.
Industrial Coating
Blast-prepared substrate with industrial coating system applied for long-term corrosion resistance. Customer-specified RAL colour available for fleet branding.
Load Handling
Flat Deck. Maximum Versatility.
Unobstructed flat deck with lashing rings at regular intervals. Load whatever you need — concrete elements, steel sections, machinery, or mixed cargo — and tie it down properly.
Load Restraint System
Heavy-duty lashing rings welded to the main frame at regular spacing. Sized for direct attachment of ratchet straps, chains, and tensioners for EN 12195 compliant load securing.
Steel or Timber Floor Options
Bare steel deck for maximum durability and cleanability, or hardwood timber decking for better grip and reduced damage risk to sensitive cargo — specified to order.
Running Gear
Air Suspension System
Full air suspension on all axles provides a smooth ride for sensitive cargo, maintains consistent platform height at different load weights, and protects road surfaces in compliance with European regulations.
Electronic Braking System
EBS electronic braking system delivers precise, proportional braking across all three axles — ensuring stable, controlled stops even under maximum load with no brake imbalance.

Material & Engineering FAQs
What is Hardox steel and where is it used in trailers?
Hardox is a wear-resistant steel manufactured by SSAB, specifically designed for applications requiring exceptional abrasion resistance. Grades vary from 400 to 500 HBW.
Technical Details:Typical applications include dump truck bodies and loader buckets. Service life can be 3-5 times longer than conventional steel.
What are the welding requirements for high-strength steels?
High-strength steels require specialized welding procedures to maintain mechanical properties and prevent defects, including preheating for thicknesses > 20mm.
Technical Details:Welding procedures must be qualified according to EN ISO 15614. Heat input typically limited to 0.8-2.5 kJ/mm.
