Mercedes-Benz Special Trucks will be showcasing the Arocs 4652 AK 8×8/4 semitrailer truck with Hyva hook lift (Titan 30 65 SK) and Bruns roll-off load compartment floor (AGPS 7500), the Mercedes-Benz Zetros 3351 A 6×6 with automatic transmission, the Mercedes-Benz Zetros 4042 AS 6×6 with hydraulic double winch made by HPC (TLS 2.20) and the Mercedes-Benz Unimog U 4000 with soft top. Some of the vehicles have been specially configured for areas with dry, hot and sandy environments.
The vehicle showcased at IDEX 2023 is the tried-and-tested Unimog U 4000 with a long wheelbase. The OM 924 LA Euro III in-line four-cylinder engine with a displacement of 4.8 liters delivers an output of 160 kW (218 hp)/810 Nm. The dimensions of the Unimog 4000 are (L x W x H) 5,920 mm x 2,336 mm x 2,558 mm with a wheelbase of 3,850 mm. The permissible gross mass is 9.5 tons (4.4 tons on the front axle and 5.3 tons on the rear axle).
The variability of the Unimog is given a whole new dimension by the cab with folding top. With this version, the roof can be folded away. The plug-in windows of the doors can be removed and stowed in the cab. The windshield can be folded forwards. A roll bar has been optionally integrated into the body for crew safety. After having removed the cab body, the driver and front passenger have all-round visibility limited merely by the body. By reducing the vehicle height, transportation by air freight or below deck on ships is made easier. In addition, the vehicle is suitable for low passages that are otherwise impassable for vehicles of this weight class.
Mercedes-Benz Special Trucks offers a very special solution for customers thanks to the folding top available for this model series. The basis for the uncompromising off-road capability of the Unimog U 4000 is the flexible frame with tubular cross members. It ensures the necessary stability on the road while also being able to twist off-road. This is ensured by the three-point mounts for the cab, engine, transmission and body, as well as defined interfaces for attachments and bodies. This means that even deflections of 500 millimeters are possible.
The Unimog with torsion-free platform as well as bow and tarp is the ideal transport and logistics vehicle for remote areas with inadequate or destroyed infrastructure. Folding benches for transporting people can also be set up on the platform. Portal axles give the Unimog its very high ground clearance. This means that it can even cope with rough terrain and obstacles up to half a meter high. Thanks to a reduction on the hub reduction gear, the full torque is effective on the ground – for increased traction on difficult terrain. With a fording capability of up to 1,200 millimeters and a tire pressure control system, there is hardly a swampy landscape or dry desert that the Unimog cannot cope with.
