Welcome to a clean city: MAN at IFAT 2014

MAN is showcasing new Euro 6 vehicles for municipal needs.

MAN Truck & Bus is appearing at the IFAT Show 2014 in Munich from May 5 through 9 in hall C4 at booth 311. The focus is on the new MAN chassis that meet Euro 6 exhaust limits. Five vehicles from the TGM and TGS series demonstrate MAN competence in waste management, winter services and road maintenance.

"Waste disposal, street cleaning and winter services are tasks that the public expect to be handled smoothly and reliably. Communities and operators depend in turn on economical and environment-friendly vehicles. MAN chassis and special-to-sector bodywork are closely matched for the purpose. At the show you can see the result of intensive cooperation between our engineers and bodywork producers – application-specific Euro 6 vehicles presenting the customer, the operator with optimal "tools for the trade". The wide range of MAN products offers operators a high level of flexibility", says Heinz-Juergen Loew, Marketing, Sales & Services director of MAN Truck & Bus.

The extensive MAN commercial vehicle selection ranges from 7.49 to 44 tonnes. Vehicles of the TGL, TGM, TGS and TGX series offer many application-specific features for community services and waste management. These include matching power takeoff, winter services hydraulics, special changing logic of the automated MAN TipMatic gear change for waste collection vehicles with a convenient control element on the armrest of the driver's seat, adapted chassis for setting up sweeper machines with reduction gearing for low speeds, steered leading and trailing axles for high load capacity plus excellent manoeuvrability in city traffic – to name just a few examples of the wide selection of application-specific configurations of MAN chassis. Added to this, for markets beyond Europe – primarily in Asia and Africa – there are the rugged chassis of the MAN TGS WW and CLA series.

At MAN’s booth, the new Euro 6–compliant engine will be at the forefront.

At IFAT 2014, the world’s leading trade fair for the water, sewage, waste, and raw material industry, MAN will present a wide range of practical solutions from May 5–9, 2014, in Munich. These will comply with the applicable emission standard Euro 6, which will be in force from the beginning of 2014. For special tasks in waste disposal, road maintenance, and winter road maintenance, municipalities and contractors need reliable and economical vehicles. To achieve this, bodies specific to the industry as well as attachment devices and MAN’s chassis have to work closely together. MAN offers customised chassis with environmentally-friendly drive technologies.

Efficiency in operation and vehicle maintenance begins for the entrepreneur with the choice of tailor-made vehicle/body combinations: It offers an extensive program of 7.49–44 tons in the TGL, TGM, TGS, and TGX truck series. For markets outside Europe, mainly in Asia and Africa, MAN’s sturdy chassis ranges TGS WW and CLA come into play.

One of the highlights at the MAN booth will be the MAN TGM 18.290 sweeper chassis. The right-hand drive version with an industry-specific C cab runs on the larger 22.5-inch tyres in order to offer ground clearance for accessories, such as sweeper brushes and vacuum chutes on and under the frame. New features include the modified position of the Euro 6 exhaust gas components, the so-called Euro 6 sweeper package, equipped with the MAN TipMatic automated gearbox combined with a hydrostatic drive.

The hydraulic system is powered via a geared auxiliary drive. It supplies the functions of the body with energy. The oil motor integrated into the drive train also moves the vehicle and thus ensures very low speeds for special sweeping actions of 0.9 km/hour.

The vehicle MAN TGS 26.360 to be presented at IFAT 2014 is designed for efficient work flow in waste disposal. The right-hand drive, three-axle air-sprung chassis is prepared for attachment of a side loader. In this collection system, the tipping device with its hydraulic arms for lifting the container is located on the right-hand side space of the chassis. This means that components which would normally be fitted in that area when using a standard chassis with Euro 6 exhaust system, have to be moved elsewhere. In close cooperation between MAN and body manufacturers, a solution was found that allows for the space that the tipping requires.

The collection round with side loaders also requires many stops and go's in a very short distance. This challenge triggers a new shift pattern of the automated gearbox MAN TipMatic, the so-called side loader TipMatic. This software application allows for short response times for many start-up and manoeuvring procedures from dustbin to dustbin in combination with the control of the side boom.

MAN offers vehicles equipped with Euro 6 engines for diverse waste disposal tasks.

Household or commercial waste, bulky goods or organic waste, recycled materials, waste paper, or hazardous waste – for each type of waste, the market offers special collection and transport technologies and strategies. In addition to this: On the one hand, high traffic loads in cities with less and less space for traffic demand compact and manoeuvrable waste collection vehicles. On the other hand, the need for large transport capacities with larger container volumes and therefore more robust chassis is increasing. Centralisation of the network of waste disposal facilities, such as landfills or thermal treatment plants, leads to longer transport routes between the collection and the unloading point. Manufacturers of systems and chassis have to address the many challenges.

MAN’s vehicles meet diverse needs and range from light and manoeuvrable vehicles with dual axes in the TGL and TGM series to chassis with two, three, and four axes, which are available in the TGS series. Manufacturers of chassis have adjusted their product range closely to different loading techniques, such as front, side, or rear loaders.

After adapting to the exhaust emission standard Euro 6, which will come into force on December 31, 2013, MAN, in accordance with the specification of the market, now offers all chassis from the older series in emission categories Euro 3 to 6. By introducing the very effective, but technologically sophisticated emission control system for Euro 6, MAN, in close coordination with body manufacturers, has developed practical solutions. It had to take the increased space requirements for components such as the exhaust system and AdBlue tanks into account, which are larger compared to Euro 5.

MAN’s versatile product range for waste collection

Due to its many options, MAN’s TGS series is made for this industry. The range comprises two-axle trucks with an 18 ton gross vehicle weight of up to 32 tonnes with four axes. The three-axle version is the most common in the waste disposal industry. With its load-bearing capacity and manoeuvrability, the TGS featuring a factory-fitted 9 ton trailing axle takes a leading position. This load-bearing capacity serves for better weight distribution in vehicles that, due to their bodies, are tail heavy. From a technical point of view, installing this trailing axle increases load bearing of the front axle and thus increases the flexibility in each load status.

The MAN TGL, with its body of 9 m³ and its high degree of manoeuvrability, is ideal for narrow streets and old towns. MAN’s TGM series offers two- and three-axle vehicles to choose from, which accept large containers of up to 22 m³. The three-axle TGM featuring a gross vehicle weight of 26 tons, which stands apart with its payload-optimized design and with its lifting trailing and leading axles, is part of the product range. All TGL and TGM series have spacious C and L cabs. The TGM series features a low two-stage entry into the C cab of only 360 mm, depending on the load, which is a very convenient feature for workers. A centre seat fits into the cabs, ideally for a third person for collecting and emptying waste containers.

Waste collection trucks from the MAN TGM and TGS series also meet the high requirements of the ASF norm DIN EN 1501-1in the Euro 6 configuration.

Convenient and ergonomic switch element for waste collectors

On a collection round, the driver is constantly on the move, shifts, brakes, and stops between loading points, which are typically only a few meters apart. In addition, each time he has to turn the emptying and pressing functions on and off. The driving profile of a collection round therefore differs fundamentally from other areas of deployment for commercial vehicles. That is why MAN fits the chassis of a collection vehicle in the TGM and TGS series with important technical features, which help the driver do his job. By using controls mounted on the armrest of the driver's seat and the MAN TipMatic, designed specifically for deploying collection vehicles with rear-end loaders, the use of all functions can be easily activated. By pressing the button, the driver is able to activate all body-related functions. In the neutral position, he is able to use the hydraulic system in the body. A rocker switch on the control unit sets the automatic brake. During loading, the driver does not need to place his foot on the brake. If the vehicle rolls to the next loading point, it will brake automatically at a speed of less than 2 km/hour and come gently to a halt, while holding a constant brake pressure. If the driver presses the accelerator pedal after the end of the loading cycle, the brake will be released again automatically.

At IFAT 2014 for use as a road sweeper MAN is showing a Euro VI chassis specifically for these purposes from the TGM vehicle series.

In technical terms road sweepers are far from ordinary vehicles. Slow speed when sweeping, compactness plus manoeuvrability, and large add-on units attached to the side of the frame and beneath the chassis are all striking differences from other kinds of commercial vehicle.

Operators also expect a typical road speed of about 80 km/h to move between different points of use. To clean streets, squares and the like sweepers drive very slowly at less than 3 km/h. With a manual gear change MAN vehicles can operate at a sweeping speed of 2.7 km/h. Integration of a step-down transmission in the power train enables speeds between 0.9 km/h in first gear and 2.2 km/h in fourth gear.

When it comes to the driver's seat operators prefer righthand steering where traffic drives on the right to give a driver the best possible visibility of kerbs. The extent to which the side windows of MAN cabs can be dropped plus the wide-span mirrors on both sides support them in their work.

On the chassis of all MAN series it is possible to implement differently sized road sweeper bodies of between four and eight cubic meters capacity. For the biggest market segment – double-axle road sweepers capable of holding seven cubic meters – MAN offers an appropriate chassis from the TGM series with a very short wheelbase and C-scale driver's cab. Road sweepers need plenty of space on the frame, between axles as well as ample ground clearance for roller brooms, whisk brooms and suction devices, so this version of the MAN TGM comes with larger 22.5-inch tyring. Extensive modifications are necessary on the chassis to create the necessary space for the road sweeper body. MAN supplies bodywork producers with all required setups and interfaces.

At the IFAT show MAN is presenting the Euro VI version of MAN TGM 18.290 with a gross vehicle weight of 18 tonnes. A wheelbase of 3575 mm available straight ex works guarantees optimum manoeuvrability. For this kind of application MAN recommends air suspension on the rear axle to produce a constant driving level. Then the height of brooms and suction duct need not track with the load to maintain the same level above the road surface.

Introduction of more sophisticated Euro VI exhaust technology as of December 31, 2013 places extra demands on bodywork producers. Despite the increased space need for this exhaust system, MAN has repositioned all chassis structural parts so that the MAN TGM will still support bodywork for up to seven cubic meters of road sweeping capacity. Modifications include shifting the exhaust system, the battery box and the air tank away from the frame to an assembly carrier directly behind the cab. Extra to this, specially shaped aluminium diesel tanks holding 160 or 200 liters can be placed on the rear of the vehicle. Air vanes under the radiator and engine prevent any swirling of dust when the cooling fan turns on.

Hydrostatic drive for sweeping system and vehicle

An increasing number of operators do away with installing a separate drive motor for sweeping and suction. Instead they opt for a hydraulic system that draws its driving energy from the vehicle engine. In technical terms most bodywork producers solve that by drawing power from the takeoff at the flywheel or gearing end.

As an extra to the familiar road sweeper chassis the interface for a hydrostatic drive is presented. This can be operated over the power takeoff at the gearing end. That enables optimum matching of speed when sweeping. When driving out to and returning from a road sweeping assignment, the driver can make use of the convenient, automated MAN TipMatic gear change.

In ecological terms, doing away with an extra motor in the body that produces noise and exhaust gas, as well as limiting payload, is an ideal solution. In the vehicle set up for the MAN exhibition booth together with Faun Viajet, a hydrostatic drive works in place of the engine for sweeping operation. The MAN engine drives the hydraulic system over a power takeoff. On the one hand this powers the functions of the bodywork. Plus it drives an oil pressure motor integrated in the drive train that acts on the drive shaft and drives the rear axle.

MAN vehicles in many versions serve as suction and flushing vehicles.

Emptying drainage shafts and pits, rinsing ducts or extracting sludge, are the usual areas of deployment of high-pressure flusher and suction vehicles or vehicles with combined high pressure flushing and suction. Entrepreneurs working in the waste disposal industry and the local operators of these vehicles concentrate on efficiency and optimal coordination between body and chassis.

The flexible MAN TGL and TGM are recommended for use in narrow streets and backyards. MAN’s three axle trucks of the TGM and TGS series are best suited for these specific industrial jobs. These trucks are equipped with a steered trailing axle and therefore are extremely flexible and offer optimum weight distribution. The product portfolio of the MAN TGS series features more suitable axle configurations: steered leading axles, rigid or steered trailing axles as well as a dual axle unit. The steered trailing axle is licensed for a load up to nine tons. The four-axle of the TGS series rounds off the product range

The MAN engines with four cylinders in series TGL and TGM and with six cylinders in series TGM and TGS convince through cost effectiveness, low noise emissions and powerful auxiliary drives that power the structural components. The engines meet the exhaust emission limits of Euro 6, which comes into effect on 31 December, 2013.

Due to their construction, suction and flushing vehicles have a high center of gravity and load concentration. It is therefore advisable, to use the equipment available in the MAN TGS range with high-load roll stabilization in combination with Continuous Damping Control (CDC).High-load roll stabilisation in combination with continuous damping control (CDC) is advisable. Reducing the lateral tilt, as well as pitching and rolling movements lead to greater safety when cornering, for rapid lane changes and strong braking.

For the transport of dangerous goods, appropriate ADR versions of the vehicles are available.

Not only in winter but all year-round - at IFAT 2014, MAN shows two lorries in Euro 6.

The communal and urban yards, road and highway maintenance companies, and their subcontractors clear snow, clean roads, and carry out repairs on the road surface, signs, and lighting, as well as maintain the roadside greenery. Throughout the year, their trucks must be ready for use, and to be able do this, they have to be easily converted for summer and winter tasks. Here, the MAN chassis of the TGL, TGM, and TGS series is the winner as a three-way tipper and a tipper for loading cranes and elevating platforms, as well as with bodies such as mowers or spreaders for road maintenance in winter.

MAN TGS: the master for winter

At IFAT 2014, MAN at its booth will present a three-axle MAN TGS 28.400 BL 6x4-4 in the new Euro 6 version, which features a side plough. In winter, the road maintenance departments prefer this type as it excels due to its branch-related drive train design: MAN offers ex-factory a steered and lifting trailing axle. Because of this feature, it is less than a two-axle but provides the payload of a three-axle vehicle. The front axle and the first rear axle are driven. On the one hand, this ensures maximum traction when clearing snow due to the heavy front shield and offers a high payload for loading gritting materials such as road salt, wet salts, or liquid de-icing salts. On the other hand, raising the lifting axle optimizes the economic use if no heavy load has to be carried around.

Conversion of the MAN-made chassis to the exhaust emission standard Euro 6, which will be in force from December 31, 2013, onward, limits the usability of the side plough. Especially on highways, road maintenance vehicles with snow ploughs are deployed to clear several lanes of snow. MAN has applied the components of the Euro 6 exhaust-cleaning system that is usually mounted on the right-hand frame in such a way that the side plough will continue to have its space.

The MAN TGS offers a special technical feature. The innovative drive system MAN HydroDrive with its switchable hydrostatic front-axle drive offers additional traction.

For municipal use of two-, three-, and four-axle vehicles of the TGS series, MAN offers the necessary preparations ex-factory. In the field, the standardized panel of the device, which is within easy reach next to the hydraulic connections, and the additional light and flasher units, which have been positioned higher, will be noticed. In the cab, controls for the snow plough and spreader are within easy reach for the driver, fixed on the dashboard next to the steering wheel or on the armrest. Installation of winter road maintenance hydraulics rounds off the equipment package for winter service.

MAN TGM: the flexible all-wheel drive

MAN will also present a very compact version of the TGM with an all-wheel drive at its booth. With a wheelbase of 3050 mm, it meets the high requirements of flexibility when clearing snow in close streets overrun with parked cars, as well as on large squares and car park facilities. Here, vehicles are needed that are easy to use. Therefore, controls for the ergonomically optimized hydraulics for winter road maintenance have been arranged optimally near the driver's compartment.

A speciality of the TGM series with a gross vehicle weight of 13 to 15 tons and all-wheel drive is the standard air suspension of the rear axle. It ensures maximum protection of the load from bumps and keeps the driving level always the same. The advantage of the system proves itself in winter. Regardless of the load condition of the attached spreader, the loading area and spreading disc remain always at the same height level, and the set spreading level does not have to be readjusted during the tour. In year-round use, the driver changes the devices on the loading area several times a year on the yard. Supported by air suspension, this can be done quickly and easily. Bleeding the suspension bellows on the rear axle lowers the vehicle by 9 cm or lowers it by 13 cm, all on the touch of a button. With only a few clicks, devices can be attached or taken off.

For the TGL series with a gross vehicle weight from 7.49 tons upward and TGM series from 11.99 tons upward, MAN offers the most spacious double cabin for up to seven people in its program. As such, employees of road maintenance, maintenance of green areas, or horticulture will arrive comfortably at their workplace. The double cabins in a fully galvanized all-steel body, along with other cab models, are produced at the Steyr plant (Austria).

MAN’s swap-body vehicles score points when transporting waste and recyclable materials.

There are diversified transport orders when dealing with waste that have to be sorted by material and processed further. Roll and air-drop container systems optimise the flow of recyclable materials as flexible storage and transport containers. The containers are easy to load and unload, can also be used for interim storage and make transfer handling superfluous. As vehicles for carrying containers of 4–40 cubic metres, the entire product fleet of MAN is at your disposal. Swap systems of roll and air-drop containers can be put on the two-, three-, and four-axle chassis of the TGL, TGM, TGS, and TGX series.

The MAN chassis with air suspension offers a high payload capacity. For lifting and setting down containers, the air suspension may be lowered. This, in turn, increases stability and reduces the overall height during the changing process. Due to the high construction type and associated high centre of gravity, it is recommended to fit high-load roll stabilization combined with a continuous damping control (CDC). In the TGS series, these systems reduce body roll as well as pitching and rolling movements This leads to greater safety when cornering, when performing rapid lane changes, and with strong braking.

The construction access step helps the driver look at the load in the container. MAN offers this as a big platform on the front fenders and a long handrail on the cab roof.
