Product description
Three-way tipper with overrun brake
The tandem tipper carries 5.720 kg with a permissible gross weight of 8.000 kg and tips to three sides. The overrun brake means it does not depend on the towing vehicle's braking system – just 46,8 PS is required.
Overrun brake – the defining feature of this model
This is what sets the trailer apart from versions with air or hydraulic brakes.
How it works: When braking, the trailer pushes against the towing vehicle. The overrun device in the drawbar is compressed and operates the wheel brakes – purely mechanically, with no connection to the tractor.
What this means:
- No braking system is needed on the tractor. No air brakes or hydraulic trailer brakes.
- Suitable for any sufficiently powerful towing vehicle. Older tractors, compact tractors, wheel loaders and telehandlers without a brake connection.
- No brake lines to connect. Hitch up, secure the towing eye and go.
- Less maintenance. No lines, coupling heads or seals.
Who this matters to: Businesses with a mixed fleet, part-time farmers, contractors using different towing vehicles and anyone without a tractor with a compatible braking system.
40 km/h – notable for an overrun-braked trailer
The manufacturer specifies a permissible speed of 40 km/h.
Why this is not a given: In Germany, overrun brakes on agricultural and forestry trailers are usually limited to 25 km/h.
How this relates to gross weight: The permissible gross weight is exactly 8.000 kg – and that is no coincidence. Under European regulations for agricultural and forestry vehicles, overrun brakes are also permitted at higher speeds up to this weight limit.
What this means for approval: This figure applies to individual approval in Germany. The specific speed entry should be checked with the registration authority or an expert before purchase – this is important for a trailer used on public roads.
EU type approval for €308 – with no loss of payload
This is one feature that sets this trailer apart from many others.
| Individual approval | EU type approval | |
|---|---|---|
| Permissible gross weight | 8.000 kg | 8.000 kg |
| Speed | 40 km/h | 40 km/h |
| Surcharge | – | 308 € |
Why this is worth noting: For many trailers, EU type approval comes at the cost of payload – often several tonnes. Here, weight and speed remain unchanged.
Included in the package: CoC documents, 40 km/h approval under EU Regulation 167/2013 and a lighting system with side marker lights.
Who benefits: Anyone using the trailer across regions, selling it or taking it abroad. At €308, this is one of the most affordable type approvals in the range.
4 mm floor and 2 mm side panels
The sheet thicknesses have been deliberately selected to differ.
Why the floor is thicker: It carries the entire load and is directly struck when loading with a bucket or grab. When tipping, the material slides across it – this is the most abrasive wear on the entire trailer.
Why 4 mm is a good choice: It stands up to bulk materials, rubble and soil without unnecessarily increasing the unladen weight. With an unladen weight of 2.280 kg, the payload remains 5.720 kg – a favourable ratio.
Three-way tipping – with safety system
The tipping direction is selected using two pins.
What the safety system does: It prevents the wrong side from being left unlocked by mistake when tipping. If both sides are accidentally left unlocked, the body can slide off while tipping – this is the classic cause of accidents with three-way tippers.
Tipping angles: 50° rearwards, 46° sideways. This is sufficient even for cohesive materials, which can stick at shallower angles.
Central locking on three sides
All side panels can be opened and closed centrally.
Why this matters in everyday use: With individually locked panels, several catches have to be operated before each tipping operation – and locked again after loading. This takes time on every cycle and, in practice, is easily forgotten.
Grain outlet in the rear panel
A detail that makes the trailer suitable for transporting grain.
What it does: It allows a controlled flow without fully opening the rear panel. When unloading into a pit or elevator, the flow can be controlled, rather than releasing the entire load at once.
To complement this: Optional extras include a grain unloading auger with a capacity of 30 t/h and a discharge chute.
Parabolic suspension
The axle suspension uses parabolic springs instead of leaf spring packs.
The difference: Parabolic springs consist of a few leaves that taper in thickness. They provide softer, more even suspension than layered leaf springs.
The benefits:
- Gentler on the load – fewer jolts when empty or partially loaded.
- Gentler on the trailer – less stress on the frame and body.
- Less friction between the leaves – reduced wear.
The extension option doubles the volume
As standard, the trailer holds 4,9 m³ with a side panel height of 500 mm.
| Version | Side panel height | Volume | Surcharge |
|---|---|---|---|
| Standard | 500 mm | 4,9 m³ | – |
| with extensions | 500 + 500 mm | approx. 9,7 m³ | 1.667 € |
| Mesh extensions, 8 mm mesh | 500 + 1.000 mm | greater | 2.436 € |
| Mesh extensions, 30 mm mesh | 500 + 1.000 mm | greater | 2.007 € |
When extensions are needed: With lightweight bulk materials such as grain, wood chips, manure and silage, volume is the limiting factor, not weight.
The calculation: 4,9 m³ of grain weighs around 3.700 kg – so the body is not fully used with a permissible payload of 5.720 kg. Extensions allow the payload to be fully utilised.
For heavy materials such as gravel, sand and excavated soil, the standard version is the right choice – the weight limit is reached first.
From 46,8 PS – low tractor power requirement
This is one of the lowest requirements in the tipper range.
What this means in practice: The trailer is suitable for compact tractors, older tractors and smaller machines. Combined with the overrun brake, this makes it compatible with a very wide range of towing vehicles.
For the hydraulics: The telescopic ram requires 13 litres of oil at 200 bar – practically any tractor can supply this.
Important accessories
| Equipment | Price | Benefit |
|---|---|---|
| EU type approval with CoC | 308 € | 40 km/h under EU law, with no loss of payload |
| 500 mm extensions | 1.667 € | doubles the load volume |
| Roll-over cover with frame and platform | 1.451 € | Secures bulk loads |
| Side panel lifting springs | 151 € | make opening easier |
| Rear sheet-metal chute | 151 € | controlled unloading |
| Plastic mudguards | 151 € each | protects towing vehicle and trailer |
| Spare wheel 11,5/80-15,3 | 206 € | reduces downtime |
The roll-over cover is more than just a convenience: When transporting bulk materials on public roads, the load must be secured against falling off.
Applications
Agriculture and part-time farming, agricultural contractors, landscaping, local authorities and public works departments, riding centres and equestrian businesses, forestry, construction and trades, equipment hire.
Operating notes
- Check approval requirements before purchase – particularly the registration of the permissible speed with an overrun brake.
- Check that the Ø 40 mm towing eye is compatible with the towing vehicle's hitch.
- Observe the towing vehicle's nose weight and permissible towing capacity.
- Check stability before tipping – use level, firm ground and avoid cross-slopes in the tipping direction.
- Set the tipping direction clearly using the pins; do not bypass the safety system.
- Before tipping, check that the opposite-side locks are closed.
- Check for clearance above the trailer – cables, gates and branches.
- Do not stand beneath the raised body; the body support is intended for maintenance work only.
- Secure the load when transporting bulk materials on public roads.
- Side panel hoops for transporting bales are not suitable for use on public roads.
- Maintain the overrun device regularly – it is the safety-critical component of this trailer.
- Check the brakes, lighting and tyres before every journey.
Frequently asked questions
Do I need a tractor with trailer brakes?
No. The overrun brake works purely mechanically via the drawbar – neither air brakes nor hydraulic trailer brakes are required.
How much can the trailer carry?
5.720 kg with a permissible gross weight of 8.000 kg and an unladen weight of 2.280 kg. The load volume is 4,9 m³.
What tractor power is required?
46,8 PS or 34,4 kW. This is one of the lowest requirements in the tipper range.
How fast can I drive?
The manufacturer specifies 40 km/h. As overrun brakes on agricultural and forestry trailers in Germany are usually limited to 25 km/h, the registration entry should be checked with the registration authority before purchase.
Does EU type approval reduce the payload?
No. The gross weight and speed remain unchanged at 8.000 kg and 40 km/h. The surcharge is 308 €, including CoC documents.
Can I increase the load volume?
Yes, with extensions. 500 mm extensions double the volume to around 9,7 m³ – a useful addition for lightweight bulk materials such as grain.
How thick is the floor?
4 mm; the side panels are 2 mm. The floor carries the load and is subjected to the greatest stress during loading and tipping.
In which directions does the trailer tip?
To three sides. The tipping direction is selected using two pins with a safety system. The tipping angles are 50° rearwards and 46° sideways.
