MAN will exhibit new models in the medium weight range at the 50th Frankfurt Motor Show next week.
A 12.170F was a surprise exhibit at the Brussels Show held earlier this year, reported by Tim Blakemore in CM January 22, but the range now covers two further 12-tonners, the 12.136F and 12.192F.
Updated versions of the basic 5.69-litre 00226 six-cylinder direct-injection diesel engine are also incorporated in the 14tonne range with similar ratings of 100kW (136bhp) at 3,000 rpm, 125kW (170bhp) and 141kW (192bhp) DIN at 2,800rpm and torque ratings of 353Nm (260 lbft) at 1,600rpm, 550Nm (405 lbft) at 1,200rpm and 620Nm (457 Ibft) at 1,600rpm.
Standard transmission with the two lower power options is a six-speed ZF S6-36 synchromesh gearbox driving through to a single reduction rear axle while a stronger ZF S6-65 is fitted to vehicles with the highest output drives through to a double reduction planetary hub axle. Specified with 9R 225 tyres the MAN 12 and 14-tonne ranges are geared for a maximum speed of 103Km/h (64mph).
Body payloads of 6.6, 6.58, 6.44, at 12 tonnes and 8.61, 8.57, and 8.44 tonnes at 14 tonnes are quoted for the different power alternatives.
In addition to rigid chassis with wheelbases 4.35m, 4.9m, 5.2m and tipper chassis of 3.2m (14ft 3in, 16ft, 17ft, and 10ft 6in) there are tractive units designated 12.170FS, 12.192FS, for operation at 26 and 32.5 tonnes. and 14.170FS and 14.192FS al& for operation at 26 and 32. tonnes respectively.
The high-tensile ladder typ frame contains an element of a loy which is said to soften th material sufficiently to alio% welding or drilling. Mounted lox on the chassis, both weight cat( gories can be specified with ful size day or sleeper cabs.
The new flagship of MAN range is the 19-361 although th 265kW (360 bhp) resonanc( charged and intercooled engir is used in trucks and bus chass from 16 tonnes gvw upwards.
Developed from the 11,4-liti unit, with capacity increased I 12 litres as the result of largi bore size and corresponding al justment in the turbochargi unit, maximum power is ava able from 1,900 to 2,200rpr while the maximum torque 1,500Nm (1,106 Ibft) extent from about 1,100 to 1,600rpm.
Combined charging and i tercooling makes use of ti vibration resonances of the intake system to improve bc torn end performance where ti turbocharger is least effectiv
