Whether power generators, water pumps or tanks, compressors, thermal containers, specialised units or mobile flood protection systems – we develop and manufacture tandem chassis tailored precisely to your application. From compact 2-tonne chassis to heavy-duty solutions with a gross weight of 25 tonnes, we produce robust, durable and practical chassis that are ‘Made in Germany’.

Our chassis are not off-the-shelf products – they are designed, engineered and built to fit your bodywork perfectly. Right from the design stage, we take into account all requirements relating to centre of gravity, axle loads, drawbar loads and subsequent use in day-to-day operations.

Individually designed – technically sophisticated

Depending on the application, we can provide:

• Chassis with a low centre of gravity and a maximum body width of 2.03 m – ideal for equipment mounted between the wheels
• Extended chassis up to 2.55 m wide for container, box or special bodywork
• Tandem chassis with parabolic or air suspension
• Versions with high-speed axles from renowned manufacturers
• Overrun braking up to 3,850 kg gross weight or air-braking with a modern EBS braking and tyre pressure monitoring system
• Customised drawbar and towing eye variants
• Bespoke support and stabiliser systems
• Special equipment such as storage boxes, tarpaulin frame structures or access aids
• Integration of TwistLock container locks as defined connection points for power units and special superstructures – this makes the power units removable and counts them as cargo

 

Thanks to state-of-the-art 3D design, the integration of your power unit or bodywork can be precisely tailored. This ensures a technically seamless, fully integrated system even before production begins.

Perfectly tailored to your power unit

The positioning of the axles and the overall load distribution are precisely tailored to your power unit and towing vehicle. This results in chassis with optimum handling, high operational reliability and maximum suitability for everyday use – even for demanding applications or heavy superstructures.

On request, we can also handle:

• the complete installation of your power unit
• the technical integration
• the load distribution test
• the final acceptance of the complete unit with the necessary registration in the vehicle documents (e.g. as a working machine or as an open-box trailer)

 

EC type-approval available

Many of our chassis can be supplied with a COC (Certificate of Conformity) or EC type-approval. This enables us to provide Europe-wide registration for complete vehicle solutions – efficiently, in full compliance with the law and from a single source.

Designed for heavy-duty use

Our chassis are used wherever reliability counts:

• mobile power supply
• flood protection
• water supply
• compressed air technology
• specialist and emergency service vehicles
• industrial and municipal applications

The latest flood protection trailers with large-area lifting flaps exemplify just how flexible and application-oriented our solutions can be – from the initial idea to the finished special-purpose vehicle.

Your project doesn’t start with a standard product – but with a solution.

Talk to us about your requirements. Together, we’ll develop the right chassis for your power unit, your bodywork and your intended use.

This 19-tonne tandem three-way tipper impresses with its high versatility: with a load volume of 13.3 m³, it is ideal for transporting bulk materials such as soil, gravel or garden waste. At the same time, machinery can be loaded easily via robust ramps with a load capacity of up to 10 tonnes. This transforms the trailer into a high-performance machinery transporter in no time at all.

Optimised for challenging terrain

The vehicle has been fitted with wide tyres for use off-road. These provide improved traction and reduce soil compaction – a clear advantage when operating on soft or uneven ground.

Legally compliant load securing with roll-up tarpaulin

Due to current legal requirements for load securing, a suitable cover is mandatory for open transport of bulk goods if the loss or falling of the load cannot be ruled out. This is set out in particular in Section 22 of the Road Traffic Regulations (StVO), which stipulates that the load must be secured in such a way that it cannot slip or fall off, even in the event of emergency braking or sudden evasive manoeuvres.

A PVC roll-up tarpaulin represents a practical and recognised solution here – particularly for light, loose or dusty materials.

The Blomenröhr tipper is fitted with an easy-to-operate roll-up tarpaulin: thanks to a crank mechanism, the tarpaulin can be effortlessly pulled across the entire loading area by just one person. An integrated platform on the front wall ensures a secure footing and ergonomic working conditions.

Unique feature: car tow bar at the rear

A particular highlight of this vehicle is the integrated car tow bar at the rear. This allows an additional trailer with a gross weight of up to 3,200 kg to be towed. In practice, this means, for example, that a shredder can be carried directly on board, feeding the material straight onto the tipper’s loading area – a huge gain in efficiency in day-to-day operations.

Maximum compatibility thanks to the multi-voltage braking system

Thanks to the modern, multi-voltage-compatible EBS braking system, the three-way tipper is compatible with both agricultural tractors (12V) and lorries (24V). This ensures maximum flexibility within the fleet and allows for universal use without any technical restrictions.

Blomenröhr – Technology that thinks ahead!

An innovative vehicle solution for efficient and safe in-line pipe rehabilitation!

Here we present a specially developed water bath trailer used in trenchless pipe rehabilitation. This robust vehicle, with a gross vehicle weight of 8.9 tonnes, has been specifically designed to facilitate the storage and temperature control of resin-impregnated liners.

In what is known as sleeve lining or liner rehabilitation, a synthetic resin-impregnated plastic sleeve is inserted into damaged pipes for drinking water, gas or wastewater. The liner is pressed against the pipe wall using compressed air and then cured using UV radiation. This creates a seamless pipe-in-pipe system that effortlessly overcomes gradients, offsets and bends. The curing process can be significantly accelerated by heat or steam – a decisive advantage for short rehabilitation times.

However, before the liner is installed, it must be stored away from UV light and in a cool place to prevent the resin from curing prematurely. This is precisely where the new water bath trailer comes in: the flatbed trailer’s body, with a volume of over 7m³, is fully lined with a pool liner fitted with a drain. A tarpaulin canopy with a sliding cover provides protection from light. Roller blinds are fitted at the front and rear. On site, the low-loader, which is registered as a work vehicle, can be filled with ice or water. After being impregnated with synthetic resin, the InLiners are pulled from the lorry onto the trailer and stored temporarily in a cool, light-protected environment. They are then fed via the shaft at the rear into the cleaned pipe section to be rehabilitated, which can be up to 200 metres long, and pressed against the sewer using compressed air. The low-loader ensures optimal storage conditions and guarantees that the resin systems retain their workability right up to installation.

With this development, we offer companies in the pipework and rehabilitation sector a cost-effective solution for modern trenchless pipe installation!

Corrosion protection has a major influence on the service life of a flatbed trailer. The combination of hot-dip galvanizing and subsequent painting—known as a duplex system or coating—is a very effective method for long-lasting corrosion protection. The zinc layer first forms a protective layer on the steel, preventing rust and mechanical damage. The additional paintwork (primer and 2 top coats) then forms an organic coating with a smooth and dense structure that prevents moisture and oxygen from penetrating the zinc layer. In addition, the paintwork offers great color design options. The combination of zinc layer and organic coating offers better corrosion protection than either layer alone – significantly increasing the service life of the vehicle!

Before painting, it is important to treat the surface with cleaning agents and a special epoxy primer. Cleaning is necessary to remove grease, oils, and zinc salts. We had the combination of these coating processes tested and approved by our paint manufacturer Glasurit before using it on customer vehicles: In the laboratory, sheets of metal with our 720h duplex coating were subjected to a salt spray test and a 240h climate test. The paint was scratched beforehand so that it could be determined whether any undermining or attack on the steel was taking place.

 

The result was clear: laboratory tests showed that our “hot-dip galvanizing + paint” coating can be certified to have a service life of 10-15 years without corrosion.

So: we can now guarantee our customers the highest level of corrosion protection and also offer visually appealing design options! Talk to us about duplex coating for your vehicle.

 

 

Invitation to the bauma 2025 trade fair in Munich
7.4.-13.4.2025
Stand outdoor area FN 623/14

Our focus this year is on low-loaders, which are suitable for the efficient transport of road construction machines such as pavers, milling machines or rollers thanks to their outstanding design details. Thanks to a particularly flat and low drive-on angle and great equipment details, the vehicles enable safe transport and easy loading!

This is guaranteed by a sophisticated design that is specially tailored to the needs of modern construction companies. For example, operating the heavy tail lifts is easier and faster than ever thanks to an innovative electro-hydraulic pump in combination with a radio remote control or mobile phone app!

Another highlight at bauma 25 is the 19-tonne three-way tipper, which has been specially developed for transporting heavy construction machinery and bulk goods. With its low loading height, wing doors and pneumatic, automatic tailgate opening, this vehicle sets new standards in terms of efficiency and flexibility.

We cordially invite all interested parties to experience the new products live and see the innovative solutions for construction machinery transport for themselves. Visit us from 7 April to 13 April 2025 at stand 623/14 in the outdoor area. Our experts will be on hand to answer your questions and provide personalised advice!

 

 

Machines used in civil engineering and road construction such as pavers, milling machines, rollers, wheel loaders, excavators etc. often have to be loaded and transported on trailers. Loading and securing – including construction site barriers – should be done quickly. Downtime on the road costs you a lot of money, especially as pavers, for example, cannot be loaded onto just any trailer. It is therefore worth paying attention to the quality of the trailer.

Pavers in particular have such low ground clearance that they can only be driven onto low-loaders with a drive-on angle of approx. 10° without any problems. We have the solution!

For milling machines, it makes sense to secure the loading conveyor quickly; for rollers, on the other hand, access is made easier if a rubber coating is fitted to the ramps. We have the solution!

Construction site barriers and construction machinery must be stowed and secured in a back-friendly manner. We have the solution!

In our more than 60 years of company history, we have received many requests from customers for the optimum trailer for road construction applications. We have compiled some of the successful implementations of customized vehicles in this brochure:

Brochure 2024: Everything for Road construction (german)!

With our many years of experience, we will be happy to advise you on how the trailer should be equipped and designed to transport your machines. Tell us about your machines and your requirements – and we will be happy to offer you a customized low-loader or tipper.

Some machines are so difficult to load due to their length, wheelbase or ground clearance that only tiltable low-loaders with a level driveway and minimum drive-on angle are suitable for transportation. This is the case with this machine – a Ruthmann Steiger:

We have developed a type 1020/10500 low-loader especially for such machines, which is very easy and quick to operate! The loading platform is tilted electro-hydraulically and the ramps are lowered. The result is a straight loading surface with a drive-on angle of just 8.6°.

 

Tilting the cargo bed is done in seconds: there is a radio remote control or a cable remote control. The power supply to the towing vehicle is established via a 2-pin NATO socket. The laterally sliding ramps have been made narrower for the riser so that the basket fits between the ramps.

Everything is made to measure and fit exactly for this machine!

 

The countdown is on! In just under 70 days from July 2024, all newly registered vehicles must be equipped with a tyre pressure monitoring system (TPMS). This is regulated in UN ECE-R141. The main requirement in the regulation: if a tyre pressure loss of 20% or a malfunction occurs, the driver must receive a warning in the cab within 10 minutes.

What is this supposed to achieve?

More safety on our roads! The RDK/TPMS warns the driver of problems in real time and thus helps to prevent accidents.
Greater efficiency! The correct tyre pressure makes the tyre more efficient and durable, reducing downtime and maintenance costs.
Sustainability! The right tyre pressure optimises fuel consumption and therefore reduces costs.

Our important message to you: we are well prepared for this and have had our vehicles tested and approved with the new equipment!
In our price list valid since March 2024, we have included the necessary equipment for tyre pressure monitoring.

This necessary equipment will be

Each wheel must be fitted with a sensor.
A control unit is required as an electronic interface to the brake system for the sensor messages
Communication between the control unit and the towing vehicle requires an electronic braking system (EBS)

We have tested and approved TPMS systems from various manufacturers for our low-loaders and tippers. We start with the following equipment and offer the following solution for our vehicles for the implementation of UNECE R-141:

1. as we need maximum flexibility with regard to tyre sizes or manufacturers in order to be able to meet the various customer requirements, we will start with a system with screw-on valves from BPW. This means that the valve sensors can simply be unscrewed and reused in the event of defective tyres. If the batteries in the sensors fail, it is easier to replace them without removing the tyre cover. Replacement wheels do not have to be fitted with sensors, but can simply be retrofitted.

 

However, the vehicle owner still needs to know that each sensor must be electronically assigned to a wheel! Otherwise he will constantly receive error messages.

Re 2: The BPW control system we have installed offers entry into telematics and thus a great additional benefit through digital data retrieval: detailed information on tyre pressure and temperature, retrieval and monitoring of EBS data, alarm settings, introduction of a digital maintenance calendar, retrieval of the vehicle position, etc. are possible

Re 3: The electronic interface also requires an EBS brake system – in other words, older ABS brake systems are a thing of the past. The required tyre pressure control cannot be implemented via this. All air-braked low-loaders and tippers will have to be equipped with EBS brake systems in the future!

The use of EBS brake systems in combination with parabolic spring units is rather exotic on the market and can lead to technical problems. However, as we have been using EBS brake systems in our trailers over 10 tonnes since 2013 and have already gained a lot of experience in this area, this changeover will not be a major challenge for us!

All 8.9 tonne low-loaders and tippers now come with automatic parking and spring-loaded brakes as standard! The 8.9t vehicles can also be ordered loaded to 9.5t GG – only the tyres change. The customer automatically has 600kg more payload.

It is not possible to equip the 5-tonne vehicles with spring-loaded brakes, as the appropriate cylinders are not available. They are still supplied with crank brakes, but are also fitted with the EBS brake system.

 

Since the desire of many construction companies to transport heavy construction machinery with three-way tippers with large single tyres and thus to have a universally usable trailer is unbroken, our development department completely revised the design of the single-tyre tandem three-way tipper last year and developed a very low and thus safe and easy-to-load tipper:
our type 890/18000-2 with wide tyres 385/55 R 22.5 and a loading area length of 5.50m has a loading height of only 1.13m – although it has 10t ramp rails inserted under the loading area! This low loading height combined with long ramp rails ensures an extremely acceptable ramp angle of 17°!

Drive-up angle of 17°, ramps with 10t load capacity per pair, weight per ramp: 66kg

With the standard loading area length of 5.50m and 600mm high drop sides, it has a loading volume of 8m³. The loading volume is sufficient for 14.6t of limestone ballast, 12t of topsoil or 12.5t of gravel. Extendable aluminium loading rails with 10t load capacity are inserted under the tipper bridge with HARDOX floor – 12t ramps (72kg/ramp) are also possible with unchanged loading height! This means that even common 10-12t excavators or wheel loaders can be loaded easily. The load floor height is kept extremely low at 1.13m, but thanks to the wide tyres it has a high ground clearance for driving in gravel pits or uneven terrain, for example.

Swinging wing door: Ramps do not need to be put down before hanging!

A completely new feature is the possible design of the rear drop side as a swinging wing door. With this option, the annoying putting down of the ramps is no longer necessary! This tailgate can also be operated very conveniently via our new automatic tailgate opening. We have chosen a pneumatic solution: when tipping backwards, two pneumatic valves give the signal to a cylinder to open or close the hooks at the rear. The valves are supplied via the trailer’s compressed air system. No further connections are necessary!

Prospekt Dreiseitenkipper 890-18000-2

 

This is also how our tipper type 890/18000-2 can be used: equipped with an asphalt thermal container for road construction! The asphalt container was built by our long-standing partner ATC-Richter from Hessisch-Lichtenau and is easily removable if the tipper is to be used for transporting machinery or bulk materials.

A trailer really cannot be used more universally!
