Key Features
Every component engineered for maximum load capacity, operational safety, and reliability in the most demanding transport conditions.
MC700 Steel Construction
The Strongest Foundation for Heavy Loads.
MC700 high-strength steel delivers 700 MPa minimum yield strength — nearly double standard structural steel — enabling maximum load capacity with reduced structural weight.
Optimised Structural Weight
MC700 steel allows thinner structural profiles while exceeding the strength of conventional ST52 steel — reducing tare weight and increasing net payload per trip.
Heavy Load Capacity
Engineered for payloads of 60 to 100 tons — purpose-built for excavators, bulldozers, cranes, and other heavy construction machinery requiring specialist low-platform transport.
Hydraulic Ramp System
Load Without Auxiliary Equipment.
The hydraulic ramp lowers to ground level, allowing tracked and wheeled machinery to drive directly onto the platform — eliminating the need for cranes or external loading ramps at every site.
Compatible with All Drive Types
The ramp geometry and surface traction are designed to accommodate both tracked machinery (excavators, dozers) and wheeled equipment (wheeled loaders, cranes) without modification.
Operator-Controlled Ramp Angle
Hydraulic actuation gives the operator precise control over ramp angle — adjustable to match ground level at each loading site for safe, smooth machinery entry.
Extendable Platform
No Load Too Long.
The telescopic bed extends to accommodate extra-long machinery and structural loads — adapting the trailer to the cargo, not the other way around.
Telescopic Bed Extension
The main bed slides to extended configuration via a robust mechanical extension system — providing additional platform length for long structural and machinery loads.
Integrated Tie-Down Points
Multiple integrated tie-down points distributed along the platform ensure heavy machinery is secured safely for transit across all road conditions and distances.
Axles & Suspension
Multi-Axle Air Suspension
Air suspension across multiple axles ensures smooth load distribution, protects sensitive machinery from road vibration, and keeps individual axle loads within regulatory limits.
Retractable Lifting Axles
Pneumatic lifting axles retract when running empty or lightly loaded — reducing tyre wear, improving fuel efficiency, and extending axle service life on unladen return trips.

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.
