Brochure: Herpa Cars & Trucks 2013 / 07-08
Type: Arocs M
Series: Construction vehicles
Mercedes-Benz has premiered a new heavy-duty construction series: Arocs.
This review premiers the Herpa Arocs model.
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. Besides the new cabs, the Herpa designers have also come up with a new, authentic chassis in over three months of work, which has been combined with a Meiller dumper.
Meiller of Munich was founded in 1850; a family company, Meiller produces innovative tipper bodies and tipping trailers, the worldwide proven MEILLER hydraulic systems, and high-quality lift doors.
All of that information may be unnecessary for this review but it was fun looking it up!
Arocs M 8X4 Dump Truck model
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 and tipper superstructure set upon a highly detailed four-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, so I did...
...however, use caution!Under the hood!
Many Herpa trucks are engineered so that you can tip the cab up to see the engine. This model has a OM 473 in-line six cylinder engine but I do not think the cab is made to tip. I tried all the tricks I've learned over the years with Herpa assembly: removing the grille; removing the front emblem; removing the bumper and whatnot; pushing forward while pulling up. No luck. I had to disassemble the entire front grille/bumper and physically unsnap the cab from the frame. Well, the cab assembly is seated upon a base which attaches the entire cab assembly to the frame using two pins in the engine as anchor!
The cab assembly is held to the motor base with tabs that you can pop out, reveling the Euro VI in all its glory.
The cab interior is held inside the cab by tabs molded as the exterior door handles. These door handles snap into slots molded in the cab sides. Once this assembly is off the chassis you can carefully
spread the cab sides away from the door handles, pop the cab off, and detail the nice cab interior.
Soft tires mounted on detailed hubs support the model. The front wheels can be made to steer if you use Herpa’s steering set. Ten soft plastic or rubber tires have nice tread detail.
The business end is a rakish 36,000 kg, 17 m³ Meiller Classic H436 rear tipper. It can be raised and features a functioning scissor-type stabilizer. The tailgate opens, too. While the telescopic hydraulic ram does not extend, it is provided as a single extended part. One end can be attached to the cylinder and the other to the front of the tipper.
Herpa created a detailed model of the chassis: gearbox, frame, fuel tanks, air tanks, axles, springs and suspension.
Individual clear lenses simulate the headlights. But the brake lights are not even simulated with paint.
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 and Grau / orange and gray. The Mercedes-Benz emblem and Arocs
is chromed, not a decal. Herpa does not use decals. The surface of the cab is glass-smooth.
This big Mercedes-Benz Arocs dump truck 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, a detailed interior which is visible through the clear windows, and the working tipper. However, there are no lenses for the brake lights.
Model railroaders of the modern era will enjoy having this just released (July 2013) truck on their layouts. Recommended.
