2 axles / 3 axles | Urban Delivery & Tight Yard Manoeuvrability
A mechanical linkage driven from the kingpin steers the last axle, which reduces tyre scrub and improves manoeuvrability in roundabouts, tight yards and frequent urban delivery points. Available in two axle configurations with side doors and in three axle configurations.
A mechanical linkage driven through the kingpin steers the last axle as the tractor turns. The trailer follows a narrower path through roundabouts, tight yards and loading zones, and the steered axle scrubs its tyres less. The system needs no hydraulics or electronics. On straight routes, the Standard Platform does the same work with fixed axles.
Platforms are 13,600, 12,500 or 10,500 mm long and carry 25 to 30 tonnes, including precast concrete beams and stairs. The two-axle and three-axle versions can have side doors for loads that need side access, and a lifting axle is available on the three-axle trailer. The welded ST52/S355J2+N I-section chassis runs on SAF, BPW, TRAX or GIGANT axles with air suspension and disc or drum brakes with EBS: chassis steel explained.

Mechanical linkage driven through the kingpin steers the last axle to reduce tyre scrub and improve turning through roundabouts, yards, and tight delivery points.
The steering system uses a mechanical linkage driven through the kingpin to steer the last axle automatically during turning. This helps the trailer track more naturally behind the tractor and reduces tyre scrub compared with configurations with fixed axles.
Designed for fleets that regularly navigate urban environments, roundabouts, tight yard entries, and loading zones.
The steered axle improves manoeuvrability by reducing the trailer’s swept path through corners. This is especially useful in roundabouts, narrow entrances, tight loading yards and urban delivery routes.
By reducing lateral tyre scrub during turning, the mechanical steering system helps support longer tyre life and lower running costs in operations with frequent manoeuvring at low speed.
The STU Mechanical Steering Flatbed Trailer is available in configurations with 2 or 3 axles. The version with 2 axles can be supplied with side doors for easier side access and structured cargo securing, while the version with 3 axles provides a classic platform layout for larger volumes of general freight.
The mechanical steering flatbed trailer with 2 axles can be configured with side doors. This improves access along the trailer side and supports a cleaner, more organised securing workflow for mixed cargo operations.
Mechanical steering is a practical choice for operators who want the benefits of a steering axle without moving to full hydraulic steering complexity. It is especially suitable for fleets that need better manoeuvrability but still prefer a robust mechanical solution.
Side doors increase access along the trailer for cargo that needs frequent loading, unloading, or securing adjustments.
Better cargo organisation and a cleaner securing routine for operators handling diverse cargo on mixed routes.
Layout with 2 axles for operators who want steering benefits in a lighter, more agile setup.
Strong welded I section chassis for demanding daily haulage.
Constant ride height with even load distribution across axles. Leaf spring option available.
Disc or drum brake configuration available. EBS (Wabco / Knorr-Bremse) for electronic braking response and stability.

Why Mechanical Steering?
Unlike a flatbed trailer with fixed axles, the last axle is steered by a mechanical linkage connected through the kingpin area. This reduces the swept path, limits tyre scrub and makes daily manoeuvring easier for drivers. For fleets working in cities, industrial zones, depots, ferry terminals, logistics yards and delivery points with limited turning space, mechanical steering provides a practical steering advantage without the complexity of full hydraulic steering systems.
In the Field
Global Reach
A system where a mechanical linkage steers the axle (typically the last axle) to reduce tyre scrub and improve turning behaviour.
Choose mechanical steering if tight turns, roundabouts, and yard manoeuvring are common: urban deliveries, tight loading zones, and frequent roundabout navigation benefit most.
Mechanical steering is actuated through a linkage; passive steering follows cornering forces. Both improve manoeuvrability and reduce tyre wear.
A configuration with 2 axles with side door access along the trailer length: ideal for cargo that needs frequent side access, structured securing workflow, and operations on varied routes.
Yes, both disc and drum brake configurations are available, combined with EBS by specification.
Yes, a lifting axle option is available to reduce tyre wear and fuel consumption when running unladen.
Air suspension for comfort and cargo protection on operations over long distances; leaf spring for simplicity and service familiarity in markets that prioritise straightforward maintenance.
Yes, configurable by specification to match your market and parts availability.
Flatbeds look interchangeable until you load them. Deck type, coil provision, steering and securing arrangement are what separate a trailer that runs profitably from one that damages cargo. Here is how to specify around your actual freight.
