In late May 2022, Daniel Zittel, the new CEO of Daimler Trucks and Buses (China) Co., LTD, arrived and will lead mercedes-benz truck import business in China in the future. In addition, Daimler trucks also announced plans to further expand its rich product portfolio in the Chinese market this year to meet the needs of different industries and application scenarios. Including 8×8, 6×6, 4×4 and other flagship models of various drive forms, Arocs will be fully blooming in the recreational vehicle, oil field, medical and rescue industries; Products including the all-new Mercedes-Benz Actros L series and Arocs SLT heavy tractor will also be introduced to the Chinese market in the coming months. So xiaobian in this article with you to review the Mercedes Arocs SLT 8X8 large tractor.

Arocs SLT, which has a towing capacity of 250 tons, carries the slogan “Making Light Work of Heavy-duty Transport” on its website, aiming to make heavy towing transportation easier and reflecting its strong product capabilities. Arocs SLT is committed to setting the benchmark in the heavy transport industry, focusing on performance while also taking into account flexibility and comfort.

Advantages:

High-torque six-cylinder in-line engine for most heavy transport needs;

The rear cooling system can ensure the normal use of engine and retarder under the condition of low speed and heavy load.

No wear turbine reducer clutch, can withstand very heavy load at the start;

Mercedes Powershift 3 16-speed automatic transmission;

Fifth wheel couplings and saddles, as well as front and rear heavy-duty couplings for traction/push applications, ensure excellent adaptability;

The rear axle is rugged and can carry a maximum load of 16 tons.

Bridge configuration

Arocs SLT has been systematically designed and manufactured to dramatically improve the efficiency of road transportation. And its rich choice of cab also greatly meet the life and work convenience in heavy transportation. Both BigSpace L and StreamSpace L wheelhouses are available in Arocs SLT.

The variety of equipment and models ensures great flexibility and adaptability to actual use

1, compressed air tank: high capacity air storage tank, to meet the needs of heavy tractor/trailer combination frequent braking;

2, fuel tank: 900 liter aluminum fuel tank to meet the demand of long endurance;

3, ladder: convenient to reach the roof for operation;

4. European VI exhaust system

5, guide shaft: 8T air suspension, hydraulic steering system;

6, the rear heavy trailer coupling: installed on the heavy frame, with gas road and circuit connection interface;

7. Trailer support plate: avoid damage to body frame and end beam;

8, sliding fifth wheel coupling (saddle), 88.9mm (3.5 “) : adapt to the total length of the vehicle group and achieve optimal axle load distribution according to different load adjustment;

9, rear cooling system: integrated cooling system, electronic water pump, silicone oil clutch water pump, in heavy load work and reducer operation to achieve the best cooling;

10, side plate with cooling air inlet: to obtain the best cooling air flow;

11, front heavy duty coupling: height adjustable reinforcement trailer coupling bracket. Push-rod can be installed to meet the requirements of pusher transportation.

The above is the introduction of some basic features of Arocs SLT 8X8. It can be seen that the 41-ton weight of Arocs SLT 8X8 meets most of the configuration requirements of a standard bulky transport vehicle, and its rigid configuration is fully satisfied.
