Mercedes-Benz Arocs Streamspace 2.3 trailer 3-axle is a new model from Herpa. This orange version is item 309912. Herpa currently catalogues 404 Mercedes-Benz models, and 3 Arocs models.

Arocs history
    The all-new Arocs is Mercedes-Benz Trucks’ third heavy-duty special vehicle. The first was the Actros for long-haulage operations, followed by the Antos for heavy-duty distribution transportation, and now the Arocs for the heavy-duty construction segment.*

Arocs is a modular system. A vehicle can be customized with a variety of fuel tanks, a new, unique suspension and frame design, wheel bases and axle configurations, four engines, and seven cab design with 14 variants to optimism an owner's requirements. Arocs are designed to be construction machines in the 18 - 44-ton class. Semi tractors, dump trucks and cement trucks are the main variants: Loader and Grounder.
    The Arocs Loader has made consistent use of every possibility to reduce its own kerb weight. The result provides payload optimised 4x2 semitrailer tractor units which are among the lightest vehicles in the construction sector, as well as 8x4/4 cement mixers with a 32 t maximum permissible weight. Thanks to their particularly low kerb weight of a maximum of 9250 kg, these vehicles are able to supply 8 m3 of ready-mixed concrete on every trip.

    The Arocs Grounder is designed for operating in extremely difficult conditions, such as in quarries or on building sites. Thanks to a host of technical measures, such as a longitudinal member thickness of nine millimetres, it is extremely robust and also features particularly high levels of stability and a high load carrying capacity.

The Euro VI engine power ranges through 16 power output levels from 175 kW (238 hp) to 460 kW (625 hp) including the brand new OM 473 in-line six cylinder engine, some with turbo-compound technology. This power is transmitted through Mercedes' PowerShift 3 automated transmission. It boasts the first electrohydraulic power steering system in a commercial vehicle.

M-B cooperated with Herpa to create these models from original plans. According to Herpa;
    For over 110 years, Mercedes-Benz has been manufacturing construction vehicles and has now repositioned its range. The Arocs is the successor of both the Actros and Axor, and was designed especially for construction vehicles. The Arocs’ most important features are its hightorque, heavy-duty drive configurations and its standard Euro 6 engines. Based on original plans and in cooperation with the developers of Mercedes-Benz Herpa has realized the Arocs series in the 1/87 scale as well.

Mercedes-Benz Arocs
Herpa securely packs this almost fully assembled model set in a form-fitted tray. The tray is held inside a red Herpa carton with a cellophane display window, and opens via tabs at each end. The tray has slots for optional parts, and slots your fingers to easily remove the tray from the box. This arraignment is surprisingly durable — past shipping boxes have occasionally been partially crushed in transit, and although a model box was mashed, the model was not damaged. Very nice!

I found no flaws in the molding or assembly. The sharply molded exterior features fine recessed lines for doors and hoods, panels and the grille. Door handles are flush and are the tabs that hold the cab interior in the cab shell.

The cab sets upon a highly detailed three-axle chassis. The windshield and windows are free of distortion and you can see the nice interior. It is worth popping the cab off to see, but I did not. Nor did I tip the cab forward to reveal the engine. If you are curious, look at the previous semi reviews as some of them demonstrate what it takes to see the engine.

Herpa created a detailed model of the chassis: gearbox, frame, fuel tanks, air tanks, axles, springs and suspension.

Individual clear lenses simulate the headlights, including tinted brake lights.

Inside of the cab is detail worth popping the cab off for: bucket seats, the steering wheel, console, stick shift, and dashboard detailing.

The windshield wipers are part of the combing around the windshield. In the front of the cab doors are slots to mount the optional side view mirrors and corner mirrors. Although the mirrors are delicate, it is a simple process.

Herpa engineered the soft plastic tires to slip over the rims. They display good tread detail.

Livery and Finish
The model components are molded in color: orange, black, and silver. The Mercedes-Benz emblem and Arocs herald are chromed, not a decals. Herpa does not use decals. The surface of the cab is glass-smooth.

Herpa has created a stunning model.

This new Mercedes-Benz Arocs dump truck and dump trailer will make an impressive presence on your layout or diorama. It has very good plastic detail and a great finish. It has a detailed underbody, lenses for headlights, driving lights, and brake lights (tinted red), and a detailed interior which is visible through the clear windows.

Model railroaders of the modern era and collectors of modern construction vehicles will enjoy having this truck on their layouts. Recommended.
