What Is a Low Loader?

A low loader (also called a step-frame, low-bed, or drop-deck trailer) is a specialised semi-trailer with a lowered cargo deck sitting between 400 and 600 mm above ground level. The "step" or "goose-neck" section drops behind the tractor coupling to create the low platform.

Deck height

400–600 mm

Payload capacity

20–60 tonnes

Hydraulic ramp / drive-on

Low loaders are specifically engineered for heavy and oversized machinery. The low deck height allows tall equipment like excavators (boom height 3.2–3.5 m) to travel within the standard 4.0 m overall height limit. Hydraulic ramps enable tracked and wheeled machines to drive on under their own power — no crane required.

What Is a Flatbed Trailer?

A flatbed trailer (platform trailer) is a standard semi-trailer with a flat, open cargo deck at 1,300–1,500 mm above ground level. The deck sits directly above the axles with no lowered section, offering a simple, versatile loading platform for crane or forklift operations.

Deck height

1,300–1,500 mm

Payload capacity

24–27 tonnes

Crane / forklift

Flatbeds are the workhorses of general haulage. Their higher deck and simpler construction make them cheaper, more widely available, and suitable for steel structures, containers, precast elements, and packaged machinery. Maximum cargo height is limited to approximately 2.6 m to stay within the 4.0 m overall height envelope.

Side-by-Side Comparison

Feature	Low Loader	Flatbed
Deck height	400–600 mm	1,300–1,500 mm
Max payload	20–60 tonnes	24–27 tonnes
Max cargo height	~3.5 m (under 4.0 m total)	~2.6 m (under 4.0 m total)
Loading method	Ramp / drive-on / crane	Crane / forklift only
Typical cargo	Excavators, dozers, mobile cranes	Steel, containers, precast concrete
Permits needed	Often (oversized / overweight)	Rarely (standard dimensions)
Cost (200 km, 25 t)	€800–€1,200	€500–€750

When to Use Each Trailer

Choose a Low Loader

Tracked machines (excavators, dozers, pavers)
Tall equipment exceeding 2.6 m height
Heavy loads over 27 tonnes
Self-propelled loading required (no crane on site)
Mobile cranes, drilling rigs, generators

Choose a Flatbed

Containerised cargo or ISO containers
Steel structures, beams, profiles
Precast concrete elements (<2.6 m tall)
Machines under 27 t with crane available on site
Budget-sensitive transport of standard-size cargo

Key Advantages

Low Loader Advantages

Self-propelled loading via hydraulic ramp — no crane needed
Low centre of gravity — safer for tall & heavy machines
Supports up to 60 tonnes on multi-axle configurations
Maximises legal height clearance for tall equipment
Ideal for tracked vehicles (excavators, dozers, pavers)

Flatbed Advantages

Lower transport cost for standard-weight cargo
Wide availability — faster booking & more carriers
No ramp needed — quicker turnaround with crane loading
Standard dimensions — no oversized permits in most cases
Versatile for palletised goods, steel, and containers

Cost Comparison — Real Scenarios

Scenario	Low Loader	Flatbed	Best choice
Excavator 22 t, 200 km	€900–€1,100	Not suitable (self-propelled)	Low loader
Steel beams 18 t, 300 km	€1,100–€1,400	€700–€900	Flatbed
Transformer 45 t, 500 km	€2,800–€3,600	Not possible (overweight)	Low loader
Precast panels 24 t, 150 km	€750–€950	€450–€600	Flatbed
Wheel loader 28 t, 400 km	€1,400–€1,800	Not suitable (>27 t)	Low loader

Frequently Asked Questions

What is the main difference between a low loader and a flatbed?▼

The main difference is deck height: a low loader (step-frame trailer) has a deck at 400–600 mm, versus 1,300–1,500 mm on a flatbed. This makes low loaders essential for tall machinery that would exceed the 4.0 m overall height limit on a flatbed. Low loaders also have ramps for self-propelled loading, while flatbeds require cranes or forklifts.

Can a flatbed carry an excavator?▼

Technically possible for small mini-excavators under 8 tonnes using a crane, but not recommended. Excavators are self-propelled machines designed to drive onto ramp-equipped low loaders. Loading an excavator with a crane is slower, more expensive, and risks damage. For any excavator over 5 tonnes, always use a low loader.

Is a low loader more expensive than a flatbed?▼

Yes, typically 30–60% more expensive for similar distances. A 200 km transport costs €800–€1,200 on a low loader vs €500–€750 on a flatbed. However, the low loader eliminates crane hire costs (€300–€800/session) and is the only option for cargo over 27 tonnes. For heavy or self-propelled loads, a low loader is often cheaper overall.

What is the maximum weight a low loader can carry?▼

Standard 3-axle low loaders handle 20–30 tonnes. 4-axle configurations carry up to 40 tonnes. Multi-axle extendable low loaders reach 60 tonnes or more with special permits. Gonera Transport operates 3-axle, 4-axle, and extendable low loaders covering the full 10–60 tonne range.

When should I choose a flatbed over a low loader?▼

Choose a flatbed when your cargo is: (1) under 27 tonnes, (2) not self-propelled, (3) under 2.6 m tall, and (4) can be loaded by crane or forklift. Common flatbed cargo includes steel structures, containers, precast concrete elements, and palletised machinery. Flatbeds are cheaper and more widely available.
