Mercedes-Benz Unimog

• Versatile and environmentally friendly

• Disaster relief and road maintenance services

• Ergonomic working area

• New technical features

The Unimog family is divided into the all-terrain Unimog and the Unimog implement carriers. Among the Unimog implement carriers, the Unimog U 216/U 218 takes on the role of the entry-level model. The Unimog model series U 318 to U 530 implement carriers are characterised by their tremendous efficiency. These vehicles are extremely capable and manoeuvrable, allowing municipal applications throughout the year.

If extreme off-road capabilities and versatility are called for at the same time, then all roads tend to lead to the all-terrain Unimog U 4023/U 5023. With a perm. GVW up to 14.5 t (U 5023), an engine output of 170 kW (231 hp) from a displacement of 5.1 l and up to 16 forward and 14 reverse gears, the all-terrain Unimog satisfies all off-road demands.

Three four-cylinder and two six-cylinder variants of the OM 934 and OM 936 engine series are available for the Unimog implement carrier series, covering an output range from 115 kW (156 hp) to 220 kW (299 hp) with displacements of 5.1 l and 7.7 l.

Disaster relief and road maintenance services – Unimog U 5023

A Unimog for special requirements is now available for public services and disaster relief work: the Unimog U 5023 is the first model from the all-terrain Unimog model series to be equipped with a municipal hydraulic system. This system allows the control and operation of a variety of carried and mounted implements such as automatic spreaders and a snowplough. The vehicle is particularly suitable for use by works depots in cities and communities at risk of flooding. Thanks to its fording capability of up to 1.2 m, and in addition to its classic assignments in road maintenance services, the Unimog can also be used to render technical assistance or for rescue operations in flooded areas.

Ergonomic working area

The implement carriers in the Unimog series provide a particularly good view of front-mounted implements thanks to the "high-visibility cab" with a particularly large panoramic windscreen, and this is improved even further by the new camera/monitor system. The interior with a new instrument cluster, multifunction steering wheel, adjustable steering column and the control stalk for the driving functions greatly contribute to driving comfort. Here the driver can easily set a preconfigured tyre pressure at the touch of a button to optimally adapt the traction and ground pressure, thanks to the Tirecontrol plus tyre pressure control system. "Road", "Sand" and "Rough road" are available for selection.

New technical features

To widen the range of applications for the Unimog even further,
Mercedes-Benz offers four-wheel steering for the Unimog U 423 to U 530 implement carriers ex factory. This allows four different steering modes: Normal steering with the front wheels, four-wheel steering with all the wheels at the same angle, "dogleg steering" for diagonal travel and manual steering of the rear wheels. This reduces the turning circle by up to 20 percent, improving the vehicle's manoeuvrability in all operating situations.

Preinstallation for body-mounted road sweepers is also available ex factory. This makes work easier for the body manufacturer. The Unimog is also available with a rear-mounted pto ex factory. This makes the full engine output available, further increasing the range of potential uses. A new lighting package as additional equipment improves the lighting conditions when driving and using implements.

Another innovative highlight offered by the Unimog implement carrier is the optionally available EasyDrive continuously variable traction drive. The synergy between the hydrostatic drive and the manual transmission allows a flying change while on the move. The new Unimog hydrostatic drive now permits speeds of up to 50 km/h – the hydrostatic power has been increased by 20 percent.

The new load-sensing hydraulics operate sensitively and precisely. The output has been increased by 30 percent, but only the output actually needed is used. This means that mounted implements are controlled particularly sensitively. The front pto shaft now transfers power outputs up to a maximum of 160 kW.

Show exhibits

Visitors to the IFAT 2016 show in Munich can find out about two application areas for the Unimog on the Mercedes-Benz stand. A particularly robust version of the Unimog U 430 with a front-mounted mulcher by Mulag and a special platform plus a frame-mounted cable winch with rear extension and slope support by forestry specialist Schlang & Reichart shows the possible applications in water management.

The second exhibit, a Unimog U 530 as the largest model in the implement series, is on display as a professional winter service vehicle for Alpine regions. For operations with an FS 105 snow blower by Schmidt, the Unimog is equipped with synergetic "Easydrive", a mechanical front-mounted pto and four-wheel steering to further improve manoeuvrability. Also included in the equipment is a four cubic metre flat-hopper wet salt spreader.

The advantages of a Unimog U 530 for municipal service were presented during practical demonstrations. The implement carrier was prepared for winter service by Dücker, Gmeiner and Dammann.
