Product description
Body tipper with three-way tipping function
The suspended tandem carries 13.690 kg and has a capacity of 15 m³, or 23 m³ with the standard 600 mm extensions. It tips to the rear and to either side – a distinctive feature for a body tipper of this size.
A body tipper and three-way tipper in one
That is the key feature of this trailer. Normally, you have to choose:
- A body tipper has a closed, sturdy body with high sides – but it only tips to the rear.
- A three-way tipper tips in three directions – but its side panels are lower and lighter in construction.
This trailer combines both: 1.200 mm-high body sides made from 4 mm sheet steel, a 5 mm floor and side tipping too.
Swinging flaps instead of opening side panels
The design solution: instead of opening the entire side panel, the body has two swinging flaps on each side, with central locking.
Why this is the more robust design: A continuous, opening side panel 1.2 m high would need heavy-duty hinges and would weaken the body. Swinging flaps are smaller, so the body’s load-bearing structure remains intact – and the central locking secures both flaps on each side together.
Three tipping configurations to choose from
| Configuration | Tipping directions |
|---|---|
| HR | rear and right |
| HL | rear and left |
| HRL | rear, right and left |
This configuration tips in all three directions. Who benefits from this: businesses that unload on either side of the road – local authorities spreading grit, contractors working at changing sites, and businesses with stockpiles on both sides.
15 or 23 m³
The standard 600 mm extensions increase the volume by more than half.
The figures: 13.7 tonnes of gravel takes up just over 8 m³ – without extensions, the trailer is the right size for heavy materials. Grain, on the other hand, fills around 18 m³, and silage over 20 m³. The extensions are needed to make full use of the payload with lightweight materials.
Well-designed extensions
These are not simple slip-on frames:
- Fitted into steel posts and secured with tensioning cables.
- Perforated viewing window with PLEXI pane – lets you see into the body while driving.
- Front vertical extension – closes off the front of the body.
- Rubber seal at the joint between the extensions and body – this keeps fine material from escaping at precisely that point.
Suspended drawbar with rubber shock absorbers
The suspension isolates the towing vehicle from the trailer. The rubber shock absorbers also absorb the load changes that occur between the vehicles when starting and braking.
As optional equipment a suspended drawbar is available for a 3-tonne drawbar load – this increases the permissible gross weight to 21.000 kg.
60 km/h as an option
The 60 km/h version is available with ALB; suitable wheels must be selected. Please note: It is not available with the CoC version.

Operating notes
- Confirm the approval route before ordering – it determines the permissible gross weight.
- Check the towing vehicle’s drawbar load: 2.000 kg, or 3.000 kg with the optional drawbar.
- Before tipping, check the central locking on the relevant swinging flaps.
- When tipping to the side, ensure the ground is level and firm – with the extensions fitted, the centre of gravity is high.
- Do not raise the body beneath overhead power lines; with the extensions fitted, the trailer is 3.150 mm high.
- After unloading, check that the body is empty.
- Drop sheets can only be used with the 600 mm extensions.
- Check the rubber seals on the tailgate and extensions regularly.
- Retighten the wheel nuts after the first few hours of operation and regularly thereafter.
Frequently asked questions
Does the trailer really tip in three directions?
Yes – to the rear at 50° and to either side at 45°. Side unloading is via two swinging flaps on each side, with central locking.
Why use swinging flaps instead of opening side panels?
A continuous, opening side panel 1.2 m high would need heavy-duty hinges and weaken the body. Swinging flaps are smaller, so the load-bearing structure remains intact.
What is the tipper’s capacity?
15 m³ without extensions and 23 m³ with the standard 600 mm extensions.
How much can it carry?
13.690 kg with a permissible gross weight of 20.000 kg. With the optional 3-tonne drawbar, this rises to 21.000 kg; with EU type approval, it is 18.000 kg.
What is the difference between HRL, HR and HL?
HR tips to the rear and right, HL to the rear and left, and HRL in all three directions. This is the HRL version.
What tractor do I need?
104 PS or 76,4 kW, and a coupling rated for a 2.000 kg drawbar load. Tipping requires 29 litres of oil at 200 bar.
Is a 60 km/h version available?
Yes, with ALB and suitable wheels. However, it is not available with the CoC version.
What is the purpose of the rubber seal on the extensions?
It sits at the joint between the extensions and body, preventing fine material from escaping at precisely that point.
