Key Configuration Choices
Lowbed trailers are configured by axle count, chassis type, ramp, platform width, suspension, and steering — the same option pool applies across all axle families.
Chassis Steel & Axle Brands
Selectable Steel Grade. Built for Your Route.
Choose S355J2+N for proven structural performance, or S700MC PLUS from SSAB for higher yield strength and reduced structural weight — both applied to the full lowbed range.
Choose Your Axle Brand
Axle brand is selectable across all models to match your service network and spare parts availability: TRAX, GIGANT, BPW, or SAF.
Air or Mechanical Suspension
Suspension type is selected by market preference: air suspension for smooth load protection and ride height adjustment, or mechanical / leaf spring suspension for durability in demanding conditions.
Rear Ramp Type
Choose Your Ramp Type.
One-piece hydraulic ramps are preferred for fast daily loading. Foldable ramps are chosen when approach-angle flexibility matters or when loading mixed machine types frequently.
Fast Daily Loading
The one-piece hydraulic ramp deploys quickly for high-cycle daily operations — allowing tracked and wheeled machinery to drive directly onto the platform with minimal setup time.
Approach-Angle Flexibility
Foldable ramps are preferred when approach-angle flexibility is important — especially when loading different machine types frequently or when ground conditions vary across sites.
Fixed or Extendable Chassis
Choose Fixed or Extendable Across All Axle Families.
Extendable (telescopic) chassis is available across all axle families — 3, 4, 5, and 6 axles. Choose fixed chassis for daily standard loads; choose extendable chassis when cargo length varies or projects include long machines.
Variable Cargo Length
The telescopic chassis extends to accommodate varying cargo lengths — suited for projects where machine sizes differ or loads require additional platform length.
2550 mm or 2750 mm
The most requested platform widths are 2550 mm and 2750 mm. The right width depends on local road limits and your typical machine width — wider platforms simplify loading and securing wide equipment.
Steering Axle Options
Self-Steering Axles
Self-steering axles steer passively based on cornering forces. Common configurations: 3-axle (last axle), 4-axle (last two axles), 5-axle (first + last two), 6-axle (first + last three).
Hydraulic Steering Axles
Hydraulic steering axles provide active steering control — preferred for tight yards, roundabouts, and narrow access points where turning radius is critical and tire scrub reduction is a priority.
In the Field
Working hard every day.
STU lowbeds are deployed in active excavator, dozer, loader, and agricultural machine transport operations across Europe and beyond.
Global Reach
Trusted across Europe.
STU lowbed trailers serve heavy haulage operators, construction fleets, and agricultural logistics companies across Europe — in 3-, 4-, 5-, and 6-axle configurations.

Frequently Asked Questions
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.
Can lowbed trailers be built as fixed or extendable?
Yes. STU lowbeds can be built as fixed or extendable (telescopic) across 3-, 4-, 5-, and 6-axle families. Choose fixed chassis for daily standard loads; choose extendable chassis when cargo length varies or projects include long machines.
Hydraulic ramp or foldable ramp — what should I choose?
Choose one-piece hydraulic ramps for fast daily loading. Choose foldable ramps when approach-angle flexibility 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 self-steering and hydraulic steering axles?
Self-steering axles steer passively based on cornering forces. Hydraulic steering axles provide active steering control — often preferred for tight route geometry and reduced tire 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 (3/4/5/6) on request.
Can I choose the axle brand?
Yes. Axle brand is selectable across all models: TRAX, GIGANT, BPW, SAF.
