Product description
Compact construction trailer with an 8.5-tonne payload
The tandem trailer carries 8.500 kg with an unladen weight of just 2.020 kg and tips backwards at 50°. The floor and sides are 4 mm thick, with four lashing points inside the body.
Four tonnes of payload per tonne of unladen weight
This is the most remarkable ratio among the construction trailers in the range: the trailer carries more than four times its own weight.
How this is achieved: The body is made uniformly from 4 mm sheet rather than having a 10 mm floor like the heavy-duty models. This saves over a tonne of unladen weight – which goes directly towards the payload.
Who it suits: Businesses that mainly transport soil, sand, gravel and excavated material – materials without the sharp edges of construction rubble and rock.
Just 62,6 PS and 5,38 m long
This is the most compact construction trailer in the range.
- Suitable for medium-sized farm tractors in the 70 PS class.
- Manoeuvrable on confined building sites, in yards and on narrow access roads.
- 2.400 mm wide – fits through entrances that wider trailers cannot get through.
- 1.560 mm overall height – also fits under low gates and canopies.
Four lashing points inside the body
Two at the front on the floor, two at the rear on the side wall.
Why their position matters: When transporting a machine or palletised goods, the load must be secured in every direction – forwards against braking forces, backwards against acceleration and sideways against centrifugal forces. Lashing points inside the body allow diagonal lashing, securing the load in all three directions at once.
Rounded front wall
The curve over the full height serves a practical purpose: material slides out completely when tipping, instead of getting stuck in the corner.
With wet soil and clay, this is the difference between an empty body and one that is still half full – and therefore between completing the job in one load and having to clear it out by hand.
All half-axles braked
A detail explicitly mentioned in the price list: the 300 × 90 mm drum brakes act on all half-axles.
Why this matters: At a gross weight of 10,85 tonnes and a speed of 40 km/h, braking force must be distributed across all the wheels. Partially braked tandem axles lead to uneven wear and longer stopping distances.
Universal drawbar for top and bottom hitching
The rigid drawbar is designed for top and bottom hitching.
Why this makes it flexible: The trailer can be hitched to tractors with a hitch coupling as well as those with a drawbar hitch at chassis height – without modification. This can save a great deal of money when using different towing vehicles on the farm or for contract work. A K80 ball coupling is available as optional equipment.
HARDOX as an option – in two versions
For tougher applications, the manufacturer offers the body in wear-resistant steel:
| Version | Coverage |
|---|---|
| HARDOX 450HB, 4 mm | Floor, side walls and front wall |
| HARDOX 450HB, 6 mm | Floor and front wall |
The difference: The 4 mm version protects the entire body, while the 6 mm version concentrates the material thickness on the floor and front wall – the areas subject to the most wear.
When it is worthwhile: when handling sharp-edged construction rubble, recycling material and rock. The standard body is sufficient for soil, sand and gravel.
There is also a hydraulic tailgate with a HARDOX surface, which tips downwards.
Up to 11 m³ with extensions
The optional 800 mm extensions with Plexi viewing window and rear swinging flap increase the volume from 4,5 to 11 m³.
When this is useful: for light materials such as green waste, wood chips, insulation waste and recycling material – where volume, not weight, is the limiting factor.
The calculation: 8,5 tonnes of soil fit into just over 5 m³ – without extensions, the trailer is suitably sized for heavy materials. At 0,3 t/m³, however, 8,5 tonnes of green waste would fill 28 m³ – so volume is the clear limiting factor.
Optional swinging wing tailgate
It opens automatically when tipping and swings freely open.
The benefit: Material flows out unhindered, and the driver does not need to watch the position of the flap. When tipping bulk material frequently, this saves time – for material that needs to be placed precisely, the hydraulic flap is the better choice.
Approval
| Approval route | Permissible gross weight | Speed |
|---|---|---|
| Individual approval, Germany | 10.850 kg | 40 km/h |
| EU type approval | 8.850 kg | 25 km/h |
| Austrian approval | – | 25 km/h only |
The difference is twofold: 2.000 kg less gross weight and a speed limit of 25 rather than 40 km/h. This should be clarified before ordering. EU type approval itself costs just 100 €.

Operating notes
- Clarify the approval route before ordering – EU type approval limits the trailer to 8.850 kg and 25 km/h.
- Austrian approval is only possible for 25 km/h.
- Check the towing vehicle's drawbar load capacity: up to 2.000 kg.
- Secure the load against movement – the four lashing points allow diagonal lashing.
- When tipping, ensure the ground is level and firm.
- Do not raise the body beneath overhead power lines.
- Before tipping, check that the tailgate can open freely.
- The body support is intended exclusively for maintenance work.
- Consider the HARDOX version for sharp-edged materials – the standard body is designed for soil, sand and gravel.
- Retighten the wheel nuts after the first few hours of operation and regularly thereafter.
Frequently asked questions
How much can the trailer carry?
8.500 kg with a permissible gross weight of 10.850 kg, depending on equipment. With EU type approval, the permissible gross weight is 8.850 kg at 25 km/h.
What tractor do I need?
62,6 PS or 46 kW and a coupling suitable for a 2.000 kg drawbar load. Tipping requires 13 litres of oil at 200 bar.
Why is the payload so high?
The body is made uniformly from 4 mm sheet rather than having a 10 mm floor like the heavy-duty models. This saves over a tonne of unladen weight, which goes directly towards the payload.
What materials is the standard body suitable for?
Soil, sand, gravel and excavated material. For sharp-edged construction rubble, recycling material and rock, the HARDOX version is the better choice.
Which HARDOX versions are available?
Two: 4 mm for the floor, side walls and front wall, or 6 mm for the floor and front wall. The latter concentrates the material thickness on the areas subject to the most wear.
Can I increase the volume?
Yes, with the optional 800 mm extensions, complete with Plexi viewing window and rear swinging flap – this increases the trailer's capacity to up to 11 m³.
Why is the front wall rounded?
So that material slides out completely when tipping instead of getting stuck in the corner. This makes a difference with wet soil and clay.
Will the trailer fit through narrow entrances?
At 5.380 mm long, 2.400 mm wide and 1.560 mm high, it is the most compact construction trailer in the range.
