Trimming off those extra pounds

That's the main aim of manufacturers at thi year's Show, and if you're a weightwatcher and who isn't these days, you shouldn't b( disappointed. Steve Gray is your guide Six and eight-wheel rigids

Bedford (Stand 44)

Bedford's turbocharged Blue Series engine gives the 6x4 TM 2600 tipper chassis extra performance and the company is showing an example of this vehicle on its stand.

Turbocharging this unit 'gives it 155kW (208bhp) of available power compared to 114kW (153bhp) of the naturally aspirated engine, at 2,500rpm.

Transmission for the sixwheeler is the Eaton 542, SMKO six-speed overdrive box, and the rear bogie is the Eaton DS380 Double drive spiral bevel. It has 3 ratio of 7.17 to 1.

The chassis kerb weight of 5.52 tonnes (6.4 tons) gives a Jo dy/ pay I oa d capability of 17.9 onnes (17.6 tons) at 24.4 tonnes 24 tans) gvw. The wheelbase of his tipper chassis is 4.45m 14ft 7in).

Another vehicle on show feauring the new power unit is 3edford's military spec 4x4 TM, he turbocharged engine of vhich was developed especially or this military application. Bedord says it has undergone strinlent durability tests.

)AF Trucks (Stand 34) An example of each of DAF's fferings in the 6x4 and 8x4 cateory is shown at the NEC this ear. The FAT2305 DHRE is a 6x4 pper/mixer chassis which has a .25m (14ft) wheelbase. trengthening has been added ) the chassis frame to suit the nigher operating conditions in le UK, and DAF says it is tailor

made for both legislation and bodybuilders' practices.

Powered by the DHRE version of the 8.25-litre six-cylinder engine it has a maximum power output of 155kW (209bhp) at 2,400rpm and 695Nm (512 lbft) of torque. ZF's six speed 56-80 synchromesh gearbox has a GV80 two-speed splitter in this application.

In addition to the chassis strengthening, the FAT2305 has heavy-duty rear springs.

Once the preserve of UK manufacturers, the eight-wheel market is being attacked by importers — and DAF is one of them. The FAD2305 DHU is shown with the standard 5.65m (18ft 6in) wheelbase and is powered by the 169kW (230bhp) version of the 8.25-litre engine. This gives 775Nm (572 lbft) of torque at 1,600rpm. The gearbox is the ZF 55-90 nine-speed all synchromesh box.

Dodge (Stand 47)

The C2464 6x4 rigid from the 300-Series is on the Dodge Stand fitted with the same day tilt-cab as the tractive units.

Dodge's BS16 six-cylinder turbocharged diesel fitted to this model gives 156kW (209bhp) at 2,200rpm. Maximum torque is 824Nm (608 (bft) at 1,400rpm. The engine is coupled to a Dodge 813 eight-speed rangechange gearbox. Also available is the C3084 8x4 chassis.

ERF (Stand 39)

A 6x4 M-Series and an 8x4 are the rigid exhibits on ERF's Stand.

The second rigid is powered by a Gardner 6LXC which gives 146kW (195bhp) at 1,920rpm and 784Nm (578 lbft) torque. This model is designed for 31 tonnes (30.5 tons)gvw and weighs in at 8.37 tonnes (8.2 tons).

Fodens (Stand 43)

With its future almost certainly secured by the intervention of Paccar, Fodens must be happier at the prospect of the NEC. Its 510 range of vehicles selling well and are representec at Birmingham by foul revamped models. Of these twc are Haulmaster rigids — one six and one eight-wheeler.

The biggest changes externally are to the front grille and the incorporation of an air scoop for driver ventilation.

New wrap-around flashers and a single-piece curved screen complete the outside appearance of the Haulmasters.

Mechanically, too, the Haulmasters have been improved, with revised clutch pedal position and a cable throttle.

Of the two rigids, the sixwheeler is a RC21/24 with 6x4 layout. It is fitted with the Cummins VT504 (which was introduced just before the Scottish' Show) and this develops 154kW (207bhp) at 2,800rpm. A Lipeil Ilway clutch and Fuller RT609 lrbox are also used.

'or the bogie, Fodens chose ! Rockwell SQK4D tandem :h a Foden FF20 rubber susnsion. The six-wheeler in this m is one of the lightest aund. Completing the speciltion is the 510 composite cab lich tilts to 65'.

3econcl of the Haulmasters is 8x4 with a Gardner 6LXC enle producing 150kW (201bhp) 1,920rpm. It too has a Lipeliway clutch but is matched to Fuller RT0950913 gearbox.
