Engine variants
In-line six-cylinder Diesel engines (R6) of the D20/D26 Common Rail range are installed in the TGS and TGX (= 1st – 3rd digitsof the engine designation). The engines are available in Euro 4 with cooled EGR and PM-Kat plus Euro 5 with SCR technology.A newly developed V8 Common Rail engine from the D28 family supplements the TGX range. In accordance with European regulations the engines are fi tted with on board diagnosis, including a NOxanalyser (with engine torque limitation in the event of NOx analyser failure).

National and international regulations take priority over technically permissible dimensions and weights if they limit the technically permissible dimensions and weights. The following data can be obtained from the quotation documents and documents contained in MANTED at www.manted.de:

1. Dimensions
2. Weights
3. Centre of gravity position for payload and body (minimum and maximum position for body)

for the production standard chassis / tractor unit. The data contained in these documents may vary depending on what technical features the vehicle is actually fi tted with upon delivery. The critical factor is the vehicle’s actual confi guration and condition at the time delivery. To achieve optimum payload carrying capability the chassis must be weighed before work starts on the body.
Calculations can then be made to determine the best centre of gravity position for payload and body as well as the optimum body length. As a result of component tolerances the weight of the standard chassis is allowed to vary by ± 5%, in accordance withDIN 70020. Any deviations from the standard equipment level will have a greater or lesser effect on dimensions and weights. Changes in equipment may result in deviations in the dimensions and weights, particularly if different tyres are fi tted that then also lead to a change in the permissible loads.

Wheels, rolling circumference
Different tyre sizes on the front and rear axle(s) can only be fitted to all-wheel-drive vehicles if the difference in rolling circumference of the tyres used does not exceed 2% or 1.5% if the MAN HydroDrive®system is installed.The basis for calculation is always the circumference of the smaller tyre. Every change of tyre type requires approval from the manufacturer. Enquiries can be made by completing the form “Request forcertifi cation”, available to download from www.manted.de or via the online certifi cation form. Any associated parameterisationwillbe carried out at the same time as certifi cation.

Calculating the axle load and weighing procedure
It is essential that an axle load calculation be completed in order to ensure correct design of the body. The weights given in the sales documents only apply to production standard vehicles. Weight differences can be caused by optional equipment or manufacturing tolerances. Manufacturing inaccuracies (within tolerances) may occur. Achieving optimum compatibility between bodywork and truck is only possible if the vehicle is weighed before any work on the body is commenced. The weights thus obtained are then taken as a basis for an axle load calculation. The vehicle must be weighed subject to following conditions:

1. Without the driver
2. With a fully fi lled AdBlue®tank and fully fi lled fuel tank
3. With the handbrake released and the vehicle secured with chocks
4. If fi tted with air suspension, raise the vehicle to normal driving position
5. Liftable axle(s) must be raised to the normal driving position (as in loaded condition)
6. • Do not actuate any moving-off aid.
