Chassis Design
The Unimog is your ideal work and transport vehicle for even the most arduous conditions. Its exceptional off-road capability is made possible through a host of technical features, such as the flexible ladder-type frame, all-wheel drive with differential locks on both axles, and the tyre pressure control system. With this, nothing can stand in the way of your perfect off-road operation. For instance, as an emergency vehicle for disaster relief work, or for maintenance tasks in the power supply industry. It gets through terrain other vehicles can't even reach – the Unimog U 4000/U 5000.
Crew Cab
Equipped with the special crew cab, the Unimog U 4000/U 5000 provides enough room for seven people and offers them maximum legroom and headroom. Four air-sprung individual seats are optionally available. Generous storage space is available in the three large compartments under the fold-away rear bench. Tools, work materials and personal equipment of all the crew members can be stored here safely, while remaining easily accessible. Additional storage compartments are located on the central console and in the front doors. The rear passenger doors open extra-wide, making it easier to get in and out. A further plus: the additional roof hatch at the rear.
Driver Information System
The driver information system (FIS) allows all important functions to be checked at a glance – including status reports, event reportsand menu-driven online diagnosis. The standard cruise control, speed limiter, electronic manual throttle control and the two-stage engine brake are all controlled with the multifunction lever on the right-hand side of the steering column. Optical and acoustic signals help the driver to respond immediately if the need arises. The radio/CD player, optionally available with a Bluetooth interface and hands-free system, further enhances operating safety.
Driving Modes
Select the proper engine mode at the push of a button to suit the job to be done. Driving mode benefits from the range of engine speeds for road trips. Working mode ensures minimal rev speed deviations.
Dual Circuit Braking System
Supported by compressed air, the dual-circuit disc braking system always bring the Unimog to a safe stop, even on long hills and with heavy loads. The braking system is perfectly reliable in any season, even after driving through mud and water. In difficult terrain, the wheels may build up a soil wedge and then become blocked, significantly decreasing the braking distance. So additional safety and driving stability is provided by a disengageable anti-lock braking system (ABS).
Advantages at a glance:
Engine
The low maintenance four-cylinder engines from Mercedes-Benz are state-of-the-art in every aspect, and perfectly equipped to fulfil every demand. Technical features include direct-injection and three-valve technology, a turbocharger and intercooler, a steep torque curve, constant output over a wide rpm range and high power reserves. The combustion-air intake is positioned on the cab roof where dust levels are lowest.
Four-Wheel Drive
With its rear-axle drive for driving on roads and the manually engageable four-wheel drive for off-road work, maximum traction is available in every situation. On extremely difficult terrain, differential locks in both axles make sure the powertrain is working at full strength. Even if only one wheel has sufficient traction, the Unimog still gets ahead and successfully tackles gradients of up to 100 %.
Advantages at a glance:
Frame
At the heart of the uncompromising all-terrain capabilities of the Unimog U 4000/ U 5000 is the flexible frame with tubular cross-members which ensures the necessary rigidity on the road while allowing great torsional flexibility off-road. This is provided by the three-point mounting of the cab, engine and transmission, as well as the defined interfaces for mounting superstructures and implements, This means that even axle articulation of up to 30° is possible.
Advantages at a glance:
Hydraulic System
The Unimog’s powerful hydraulic system with a working pressure of up to 240 bar features standard plug connectors for easy, fast and error-free fitting. Two hydraulic connections each at front and rear (pressure and return line) are available to operate winches, cranes etc.
Portal Axles
Portal axles are the secret behind the outstanding ground clearance of the Unimog U 4000/U 5000. They cope with boulders and other obstacles up to half-a-metre high. For increased traction over difficult terrain, a reduction gear on the wheel-hub drive allows for full torque transmission to the ground.
Advantages at a glance:
Power Take-Offs (PTOs)
The Unimog U 4000/U 5000 has an auxiliary drive for running hydraulic pumps for cranes or excavators. It also has a fast auxiliary drive for connecting to fire-extinguishing pumps or similar power units. The PTOs (power take-offs) are operated via a pull switch in the centre console, while the hydraulic or fire-extinguishing pumps are controlled via a special CANbus-linked module with programmable parameters.
Radiator System
The radiator system has been developed especially to cope with the high demands placed on the Unimog U 4000/U 5000. The intercooler and radiator, each with their own viscous fan, are fitted side by side, high above the ground. Thus the cooling performance is greatly improved and the danger of fouling is kept to a minimum – for optimum functional safety when fording. You can rely on the Unimog to get you through, even during the most demanding off-road operations involving temperature fluctuations or extreme dust.
Short-bonnet Cab
The position of the cab behind the engine, together with its three-point mounting on rubber elements, considerably reduces vibrationsand provides a relaxed, focusedatmosphere even for longer tasks. Optionally available luxury seats with seat-heating and lumbar supports make working a pleasure. Good visibility from the short-bonnet cab and combined with excellent handling provide great advantages, especially when working off-road in rough terrain. The optional 120 mm larger cab offers more stowage space and freedom of movement. The seat adjustment is more individual, and the cab floor is flat throughout, ensuring free through-cab access.
Short Frame Overhang
Thanks to its long-travel coil springs (instead of the typical leaf springs used by trucks), the Unimog U 4000/U 5000 has a short frame overhang at front and rear, enabling it to tackle even steep ramps and embankments with ease. Its low centre of gravity and extreme torsional flexibility provide additional security with respect to steep slopes and tipping angles.
Advantages at a glance:
Single Tyres
Unlike conventional four-wheel-drive trucks with twin tyres fitted on the rear axle, the Unimog has four single tyres. The rear wheels always run in the compressed tracks created by the front wheels, which offers higher traction and lower rolling resistance. With a wide range of tyre sizes and types available, the Unimog can be equipped with exactly the right tyres for the respective terrain.
