Introduction

Herpa's new MAN TGX XLX Euro 6c Thermo Dump Semitrailer "Trio-Trans" is an exciting semi-truck with a new thermo trailer. It is catalogued with Mfg. ID: 310673. Herpa describes this new model as:

New type! In addition to the round trough semi-trailers in the Herpa range, Herpa now also offers a new thermo trough semi-trailer. The new structure will also receive a corresponding tarpaulin, which of course will be removable. The first model will be a brand new vehicle from Trio-Trans from Friedberg near Augsburg.

What is a thermo trough semi-trailer? Historical and technical information for the thermo trough dumping semi-trailer and MAN TGX XLX can be found at the end of this review, including a link to a (German language) report concerning thermo trailer via Click here for additional images for this review.

In the Box

This is a striking set made up of two individual models: the MAN TGX XLX tractor and a thermo trough dumping semi-trailer.

They are fully assembled and packed in a light plastic form-fitted tray secured in a light cardboard box with a cellophane display window and opening ends. The TGX XLX and thermo trough dumping semi-trailer are almost fully assembled, and packed in a light plastic form-fitted tray. Included are two sprues of optional unattached parts:

• Side view mirrors
• Blindspot mirrors
• Tipper jack

MAN TGX XLX Rigid Tractor 4x4
I cannot find any flaws in the molding nor assembly, except for one small de-spruing burr on the cab rear. Like a previous MAN TGX XLX reviewed here at KitMaker Network, the exterior features fine recessed lines for doors and hoods and panels. The chassis is very detailed with the frame, battery box, fuel tanks, transmission, drive shaft, differential, axles, and suspension; topside is a fifth-wheel and the detailed cab. The front axle can be made steerable with a Herpa steering kit. Each of the six wheels have rubber-plastic hybrid tires and plastic hubcaps. They display good detail.

The windshield and windows are free of distortion. You can see the nice interior. Inside of the cab is detail almost worth popping the cab off for, with bucket seats, the steering wheel, console, stick shift, and dashboard detailing. The cab easily tilts forward to expose a detailed engine.

Individual clear lenses simulate the headlights and tinted clear lenses detail the signals, tail lights and beacons. A rack of chromed driving lights crown the cab. The windshield wipers are part of the separate black chrome combing around the windshield.

Four mirrors can be applied to the cab, a pair of side view mirrors, and two mirrors to reveal the blind areas in front of, and to the right side of, the cab. These are delicate parts on their own sprue. The plastic is slightly flexible. Carefully cut those from the parts tree or you can remove the mounting pegs; carefully fit them into the specific pre-made holes and slots. The mirror that extends to the front of the truck, it is not obvious how to mount it. Perhaps Herpa should provide some mounting instruction in the box or on-line?

Thermo Trough Dumping Semi-Trailer
I do not know what manufacturer this trailer represents; apparently several companies make them. This dumping trailer unit is a model unto itself. The underside has a good deal of detail, including telescoping landing gear. Disappointingly, none of the taillights and flashers are even painted on! That's my only complaint.

"Action features": the trough can be raised and lowered; the rear does not open; the tarp can be removed.

These models afford the modeler a good deal of detail, and even "action" features for play, or dioramas.

Livery and Markings

Both of these models are painted in striking Trio-Trans livery. While it is impressive in the box, I am engrossed with the subtle lettering and decorations. Herpa does an excellent job reproducing these markings. They do not use decals, all lettering is printed on. There is fine data on the models and it is all sharp and legible. Herpa chromed the MAN logos and other components.

The trailer is also well decorated and detailed.

All the decorations are first rate.

Conclusion

Herpa's MAN TGX XLX 4x4 and therom dumping trailer in Trio-Trans livery makes a striking set of specialized heavy duty transport. It would be hard to miss this set on a diorama, layout, or on display — especially with the trailer extended. Like the previously reviewed MAN TGX XLX set, whether you consider the models as a set or as individual components, they are impressive. Sharp molding, detailed parts, positionable features, incredible printing, all this creates an amazing set. My minor criticisms are the lack of tinted lenses for the trailer brake lights, and Herpa doesn't include directions for mounting the details parts. Regardless, this is a exciting semi-truck.

Modelers and collectors of 1/87 modern heavy duty haulage should find this a desirable set. Heartily recommended.

Please remember to mention to Herpa and retailers that you saw this model here - on Auto Modeler.

Historical and technical information

MAN TGX XLX
Rolled out to the public at the 2007 European Transport Road Show the MAN TGX is the flagship of MAN Nutzfahrzeuge Trucknology® Generation series. Declared the most powerful truck in Europe, the TGX V8 is designed to carry the heaviest loads over the most challenging terrain for long distances.

MAN TGX series is a family of rigid and articulated trucks. The vehicles are powered by 4 or 6-cylinder MAN engines of the D20 or D26 series generating from 264 KW (360 HP) up to 397 KW (540 HP), connected to an advanced MAN transmission. MAN constructs the frame in a ladder design supported by 4X2 and 6X4 axle configurations. Vehicle length is 10725 mm (35 ft.) with a GVM of 26,000 kg (57,320 lbs.).

MAN’s new 680 HP (500 KW) 8-cylinder common-rail V8 is claimed to be the most powerful in Europe. It complies with Euro 5 SCR exhaust technology standards. A MAN ZF AS-Tronic “Tipmatic” transmission transmits the power to the drivetrain. Driver reports compare the acceleration as similar to some sports cars, even under load!

For driver comfort MAN offers the option of the XLX or XXL cab.

Full standing height, full comfort: the XLX cab is designed as a long-haul cab for vehicle fleets. It captivates with its excellent aerodynamics and a powerful, elegant optical appearance.

Attention was given to safety through better all-round vision and optimized outside mirrors. Perfect for long journeys: the MAN engineers have developed a newly modelled roof spoiler especially for the XLX cab: the opening for the sliding roof has been integrated into the spoiler so that fresh air can flow through the opened sliding roof without any detriment to the aerodynamics.

Chrome and high gloss... The powerful optical appearance of the dynamic exterior is impressive and identifies dozens of new features: from the aerodynamic A-pillar trims through new LED indicator lights or position lights right up to the sleek, black radiator grille finished in chrome and high-gloss.

Thermal Dump Trucks

Use of thermally insulated vehicles when transporting asphalt mix is ​​mandatory

Certification thermal dump truck Since January 1, 2019, all tenders for road construction projects by the Federal Ministry of Transport contain the requirement to only use thermally insulated vehicles for the transport of the asphalt mix. This should improve the quality of the asphalt paving and thus also the road quality.

With a certification from TÜV SÜD, manufacturers of thermal tippers for asphalt transport can now demonstrate that their thermal troughs meet the required thermal insulation criteria. The basis for the verification is the new DIN 70001: 2018-04 , which describes the requirements for thermally insulated tipping bodies in detail, as well as the associated published requirements in the Official Journal of the Federal Ministry of Transport.

Background: Why are thermal dump trucks used for the transport of asphalt?

When building roads, there are many influencing factors that affect the quality of the asphalt and thus ultimately the quality of the roads. In addition to the manufacture and processing, this is primarily the transportation of the asphalt mix.

Optimal processing is achieved if the asphalt mix is ​​kept at a constant temperature throughout the entire transport to the construction site. However, it often cools down during transport: Neuralgic points are, for example, the corners or edges of the transport troughs. Thermal insulation of the troughs prevents cooling, makes processing easier and thus contributes to higher asphalt quality.[2]
