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.
Lowbed Trailer
2 to 8 Axles | Fixed or Extendable | Heavy Machinery Transport
STU lowbed trailers are manufactured for heavy equipment transport: excavators, dozers, wheel loaders, graders, agricultural machines, industrial cargo and oversized loads, where low loading height, rear ramp loading and stable road behaviour are essential. As a lowbed trailer manufacturer in Konya, Türkiye, STU builds fixed and extendable low loader and lowboy configurations from 2 to 8 axles, with axle, suspension, steering, ramp and deck options selected around your cargo, route and market requirements.

Key Features
Chassis & Steel
Lowbed Trailer Manufacturer
The STU lowbed chassis is manufactured around load distribution, axle family, deck geometry and route requirements. Steel selection, gooseneck structure, beam geometry and reinforcement details are evaluated according to the selected lowbed configuration.
Steel
S355J2+N or S700MC PLUS
Choose S355J2+N for economical standard builds or S700MC PLUS (from SSAB Co.) for weight reduction through stronger steel.
High Strength
S700MC / Strenx Option
Steel of high strength can be evaluated for configurations where weight matters or special requirements apply where payload logic, chassis strength and tare weight must be balanced.
Manufacturer
Lowbed Trailers Configured for Your Load
Axle layout, deck length, ramp type and running gear are selected for the machine being carried and the route it travels, so the chassis, deck and gooseneck are specified together rather than assembled from a fixed build.
Configurable
Component Choice
Axle, brake, hydraulic, suspension and tyre selections can be aligned with the buyer's market, fleet standard and service network.
Axle Families
2 to 8 Axle Configurations
STU lowbed trailers can be manufactured in families with 2, 3, 4, 5, 6, 7 or 8 axles.
3 axles
Lowbed with 3 axles, fixed or extendable
A balanced configuration for daily heavy equipment transport, excavators, loaders and regional construction machinery logistics.
4 axles
Lowbed with 4 axles, fixed or extendable
More axle footprint for heavier machines, demanding routes and stronger load distribution requirements.
5 axles
Lowbed with 5 Axles (Fixed or Extendable)
A robust project transport configuration where axle distribution, platform stability and route planning become more critical.
6 axles
Lowbed with 6 axles, fixed or extendable
A lowbed configuration offering high capacity for demanding machinery transport and constrained operations.
8 axles
Lowbed with 8 axles, fixed or extendable
A maximum multiple axle lowbed solution for oversized machinery and heavy project cargo, engineered according to route permits and legal axle load limits.
Steering Axle Options
Self Steering or Hydraulic Steering
Lowbed trailers can be configured with self steering or hydraulic steering axles. The choice follows route geometry, turning requirements and operator preference.
Self Steering
Self Steering Solutions
A practical option for improved manoeuvrability and reduced tyre scrub in configurations where self steering supports the daily route profile.
Hydraulic
Hydraulic Steering Solutions
Hydraulic steering can be applied where turning radius is critical, the trailer operates in challenging route geometry or axle movement needs closer control.
Multiple Axles
Steering for Multiple Axles
For different lowbeds, steering pattern should be engineered according to axle layout, chassis length, payload distribution and route permit requirements.
Efficiency
Tyre Wear and Yard Manoeuvring
Correct steering selection helps reduce lateral tyre scrub and supports easier handling in yards, roundabouts, industrial zones and project sites.
Ramps & Loading
Rear Ramp Loading for Tracked and Wheeled Machinery
Hydraulically operated rear ramps for safe loading of tracked and wheeled equipment. Ramp type, width and angle are selected for the machine, its ground clearance and the daily loading routine, and STU can configure single piece or foldable hydraulic ramps with two sections, or aluminium ramps and access equipment, by specification.

Frequently Asked Questions
Can lowbed trailers be built as fixed or extendable?
Yes. STU lowbed trailers can be built as fixed or extendable (telescopic) across families with 2, 3, 4, 5, 6, 7 or 8 axles. Choose a fixed chassis for daily standard loads, and an extendable chassis when cargo length varies or projects include long machines.
Hydraulic ramp or foldable ramp, what should I choose?
Choose hydraulic ramps made in one piece for fast daily loading. Choose foldable ramps when flexibility in the approach angle is important or when loading different machine types frequently.
2550 mm or 2750 mm, what platform width should I choose?
The right width depends on local road limits and your typical machine width. Wider platforms can make loading and securing easier for wide equipment.
What is the difference between passive steering and hydraulic steering axles?
Passively steered axles respond to cornering forces. Hydraulic steering axles provide active steering control, often preferred for tight route geometry and reduced tyre scrub.
Can I specify hydraulic steering axles on any lowbed model?
Yes. Hydraulic steering (hydraulic turning) axles can be configured on any lowbed axle family (2/3/4/5/6/7/8) on request.
Can I choose the axle brand?
Yes. Axle brand is selectable across all models: TRAX, GIGANT, BPW, SAF.
