MAN TGS – tried and trusted carrier of heavy loads
MAN TGS – tried and trusted carrier of heavy loads
Since their debut almost three years ago, the two-, three- and four-axle versions of the MAN TGS range have become a fixture amongst heavy-duty municipal and disposal vehicles. Three-way tippers, set-down or roll-off skip loaders, sweepers, gully emptiers, conduit-cleaning and waste-collection vehicles are some of its sector-specific versions. The TGS range offers a wide variety of axle configurations, with leading and trailing axles, suspension options and the choice between permanent and selectable all-wheel drive. Standard equipment for the 18- to 41-tonne range includes the M cab, optionally with three seats. The more spacious L and LX cabs are also available on request. Modern six-cylinder in-line engines with common-rail injection deliver outputs from 235 kW (320 hp) to 397 kW (540 hp). Depending on market requirements, the engines meet the Euro 4, Euro 5 or the even more stringent EEV exhaust-gas standard.
On all-wheel drive vehicles and optionally on vehicles with two driven axles - as used to maintain roads or for winter services, for example - the automated MAN TipMatic® transmission is equipped with the "Off-road" software. To optimise the propulsion on sand, in mud or on a gradient the gearbox has been programmed not to shift until the engine speed is higher and to keep the shifting process extremely short so that no interruption in the tractive force is noticeable.
High-load roll stabilisation in combination with continuous damping control (CDC) is advisable for vehicles with a high body or load centre of gravity. This reduces the lateral inclination and the development of pitching and rolling movements. This leads to greater safety when cornering, rapid lane changes or in sharp braking manoeuvres.
For deployment of the MAN TGS in winter service, MAN Nutzfahrzeuge offers the necessary preparation ex works. Vehicles are equipped with standardised equipment add-on plates, alongside easy-to-use hydraulic connections and the additional light and flasher units which have been positioned higher. Inside the cab the driver can find the controls for the front-mounted equipment such as the snow plough within easy reach in the dashboard beside the steering wheel or on the armrest. The winter service hydraulic system can also be installed ex works.
The MAN TGS as a waste-collection vehicle
Waste-collection trucks have special requirements for vehicle technology and in the design of the chassis. MAN Nutzfahrzeuge offers two-, three- and four-axle chassis in the TGS range which meet these requirements completely and hence provide an efficient solution for this transport task. In the course of the rear, front and side loaders' collection rounds, the weight of the vehicles and the distribution of the load in the body change constantly. The emptying system at the vehicle rear and the pressing of the laden waste lead to a heavy load on and behind the rear axle. Moreover, operators and drivers expect refuse trucks to be highly manoeuvrable since they often have to shunt around in confined conditions to reach the rubbish containers or have to move through narrow residential streets with parked cars on their collection rounds. The technical solution is a steered trailing axle with a high load-carrying capacity. This makes the three-axle truck more manoeuvrable than a two-axle vehicle of the same body length but offers a higher payload capacity and space for bodies with 17 to approx. 30 m³ containers. MAN is the only manufacturer in this market segment able to fit a steered trailing axle with a load-carrying capacity of nine tonnes ex works. This contributes to a better distribution of weight in these vehicles, which are very rear-squat on account of their body design.
The driving profile of a collection round is completely different from other areas of application for commercial vehicles. There are usually just a few metres between the loading points. The driver constantly has to move off, shift, brake and stop. At the same time the hydraulic system for emptying and pressing the refuse has to constantly be switched on and off. MAN provides a number of technical features for the chassis of waste-collection vehicles that make the driver’s work a lot easier. All the functions can be activated with ease in connection with the automated MAN TipMatic® transmission and a control panel fixed to the armrest of the driver's seat. By pressing the control button the driver can change between the drive and neutral positions on the gearbox. In the neutral position, the hydraulic system in the body is activated. A rocker switch on the control panel activates the automated halt brake, so that the driver doesn't need to keep his foot on the brake while loading. When the vehicle rolls towards a loading point, it automatically brakes at a speed of less than 2 km/h and gently comes to a halt while constantly retaining the brake pressure. When the driver activates the accelerator on completion of the loading cycle the brake is released again.
