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 behavior are essential. As a lowbed trailer manufacturer from Turkiye, STU builds fixed and extendable low loader and lowboy trailer 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 cost-effective standard builds or S700MC PLUS (from SSAB Co.) for high-strength weight reduction.
High Strength
S700MC / Strenx-Class Option
High-strength steel can be evaluated for weight-sensitive or special configurations where payload logic, chassis strength and tare weight must be balanced.
Manufacturer
Manufacturer Engineering
STU configures the chassis, deck, gooseneck and running gear as a complete system instead of treating the trailer as a generic stock product.
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 2-, 3-, 4-, 5-, 6-, 7- and 8-axle families. Each axle family can be evaluated with fixed or extendable chassis logic according to cargo length, route restrictions, axle-load rules and operating market.
3-Axle
3-Axle Lowbed - Fixed or Extendable
A balanced configuration for daily heavy equipment transport, excavators, loaders and regional construction machinery logistics.
4-Axle
4-Axle Lowbed - Fixed or Extendable
More axle footprint for heavier machines, demanding routes and stronger load distribution requirements.
5-Axle
5-Axle Lowbed (Fixed or Extendable)
A heavy-duty project transport configuration where axle distribution, platform stability and route planning become more critical.
6-Axle
6-Axle Lowbed - Fixed or Extendable
A high-capacity lowbed trailer configuration for demanding machinery transport and route-restricted operations.
8-Axle
8-Axle Lowbed - Fixed or Extendable
A maximum multi-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 either self-steering axles or hydraulic steering axles — depending on route geometry, turning requirements, and customer preference.
Self-Steering
Self-Steering Solutions
A practical option for improved maneuverability and reduced tire scrub in configurations where passive 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.
Multi-Axle
Multi-Axle Steering Logic
For different lowbeds, steering pattern should be engineered according to axle layout, chassis length, payload distribution and route permit requirements.
Efficiency
Tire Wear and Yard Maneuvering
Correct steering selection helps reduce lateral tire scrub and supports easier handling in yards, roundabouts, industrial zones and project sites.
Ramps & Loading
Rear Ramp Loading for Tracked and Wheeled Machinery
Ramp type, ramp width, ramp angle and hydraulic control options are selected according to the machine type, ground clearance and daily loading routine. STU can configure one-piece or foldable two-piece hydraulic ramps,or aluminium ramps and access equipment by specification.

Frequently Asked Questions
Can lowbed trailers be built as fixed or extendable?
Yes. STU lowbeds can be built as fixed or extendable (telescopic) across 2-, 3-, 4-, 5-, 6-, 7- and 8-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 (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.
