What is a lowbed trailer used for?
A lowbed trailer is used to transport heavy machinery and equipment: such as excavators, dozers, loaders, graders, and agricultural machines, where low loading height and stable road performance are required.

Active Axle Steering for Heavy Equipment Transport and Tight Route Geometry
The STU Hydraulic Steering Lowbed is a heavy equipment transport trailer engineered by its manufacturer designed for routes where turning control, axle coordination and tyre scrub reduction matter. Built for excavators, dozers, loaders, graders, agricultural machines and oversized cargo, the range can be configured with 2 to 8 axles, fixed or extendable chassis, hydraulic rear ramp options and bespoke components.

Hydraulic steering gives the lowbed trailer controlled axle response during manoeuvring. It is preferred when reversing, narrow entrances, roundabouts, construction sites, port terminals or project routes require more steering precision than a trailer with fixed axles or passive steering.
Controlled axle response for tight construction sites, port terminals, depots and narrow roads.
Helps limit lateral tyre scrub during turning at low speed and frequent manoeuvring.
Designed for route geometry where fixed axles or passive steering may not be enough.
Useful when the trailer must reverse into yards, warehouses or restricted delivery points.

STU hydraulic steering lowbed trailers can be evaluated from 2 to 8 axles according to cargo weight, axle load regulations, route permits, bridge restrictions and destination market requirements. Each axle family can be assessed with fixed or extendable chassis logic.
Practical configuration for daily machinery transport and tighter worksite access.
More axle support for heavier machines, demanding routes and increased stability needs.
Robust option for larger machinery and project transport requirements.
High axle footprint for heavier cargo, constrained projects and industrial loads.
Bespoke axle distribution for exceptional cargo, permits and route constraints.

The hydraulic steering lowbed trailer can be built with a fixed chassis for regular heavy machinery transport or with an extendable telescopic chassis for long equipment, steel structures, components for wind energy, industrial cargo and oversized machinery.
Efficient choice for repeat machinery transport and standard heavy equipment dimensions.
Adds deck length when cargo is longer than a standard lowbed platform.
Chassis choice should follow cargo length, transport height, axle plan and route limits.
Deck equipment, recesses and lashing points can be arranged around cargo type.

The lowbed platform helps reduce total transport height when carrying excavators, bulldozers, loaders, graders, cranes, agricultural machines and oversized industrial equipment. This supports route clearance and stable road behaviour under heavy loads.
Suitable for excavators, dozers, wheel loaders, graders, cranes and rollers.
Low platform geometry helps manage total loaded height on restricted routes.
Hydraulic or foldable ramp solutions support loading of tracked and wheeled equipment.
Recesses, widening elements and floor choices can be configured by machine type.

STU is a trailer producer from Türkiye. Each hydraulic steering lowbed configuration is guided by cargo dimensions, route data, axle count, steering system, ramp type, suspension, component brands, finish and destination market requirements.
The same option pool applies to any axle count (2 to 8) and to both fixed and extendable chassis.
In the Field
Global Reach
A lowbed trailer is used to transport heavy machinery and equipment: such as excavators, dozers, loaders, graders, and agricultural machines, where low loading height and stable road performance are required.
Hydraulic steering axles provide active steering control, dramatically reducing the turning radius. This enables access to tight construction sites and port terminals even with the heaviest loads.
Yes. STU lowbed trailers can be built as fixed or extendable (telescopic) across families with 2, 3, 4, 5, 6, 7 or 8 axles.
A removable front section that allows the tractor to drive away, leaving the deck at ground level for loading from the front of immovable machinery.
Yes. Axle brand is selectable across all models: TRAX, GIGANT, BPW, SAF.
Axle count is decided by the road, not by the trailer. Structural capacity tells you what a chassis can carry; national axle load limits tell you what you can legally put on it. Here is how to work out which number you actually need.
