HE IRTE exhibiton was omewhat over-shadowed by le conference, but there was till much to interest the opera)r at the exterior and interior isplays.
Pride of place at Mack was Iken by the new Cruise-Hauler, thich is a serious attempt by the ,merican company to go for the conventional" market rather an the heavy haulage side, /here most of Mack's UK sucess has been so far.
The Cruise-Hauler at Solihull /as fittted with a Mack inline ix-cylinder turbocharged diesel ngine developing 212 kW 285bhp). Two options of 177 nd 228kW (237 and 306bhp) will be available. The Mack enline is charge-cooled, but by a otally different system to that of nost engine manufacturers.
The charge-cooling radiator mounted on the engine itself, with the actual cooling air-flow ieing provided by a bleed-off rem the turbocharger.
With a maximum torque of 560Nm (1150 lbft) at 200rpm. Mack finds that a even-speed gearbox is perectly adequate for 38-tonne iperation. The box is a triple:ountershaft constant-mesh deign of Mack's own design in ive-speed basic form with a Otter on the upper two ratios. Vith the lower-powered engine, his basic five-speed box can be ipecified on its own. The cab as a steel shell with doors in irp. It tilts hydraulically to naximum of 60" for access. One of the most impressive eatures of the Cruise-Hauler is its weight — or rather, lack of it. It is unusual to find a 300-plus horsepower tractive Jnit designed for 38-tonne operation with a kerb weight al 5.7 tonnes (5 tons 12 cwt) which includes the fifth wheel and 270 litres (60gal) of fuel.
Renault Trucks and Buses UK Ltd used Solihull to launch the 7.5-tonne non-hgv Saviem
JK75 for this market, fohowin its debut at Brussels in Januan One of the Club of Four variant the JK75 has a 63kW (85bh engine and a five-spee gearbox. It was on show short-wheelbase form throuE Midland Continental Comme
cials Ltd, Great Bar Birmingham.
Another first-timer, so far ; Great Britain is concerned, w; the single-spine chassis fro DAF based on the 2100 serie This was shown in left-han, drive form as an rhd version K not yet been completed. Ti conversion adds arour
100kg (2cwt) to the kerb weight, bringing it up to 5.34 tonnes (5 tons 5 cwt) in the case of an FA 2105 DH for example. Although the Solihull example was shown bodied, DAF will market it in chassis-cab form only.
Lucas-Kienzle displayed its EEC automatic tachograph — "automatic' in that at automatically selects the driving mode. The instrument records driving time on the driver's chart, while duty time is recorded against the co-driver (if any). The only time the driver has to operate the switch is to record his rest periods.
Also on show from Luca% Keinzle was its chart electr,rai analysis machine, which is brand new for the UK although it was first shown at Frankfurt two years ago.
This machine — which is only compatible with the chart from the automatic tachograph produces a punch-card from the information recorded on the chart, which can then be fed ir the company's computer f improving cost / performan analysis.
Although the analyser is sale, Lucas Kienzle will also offering a chart analysis servi to operators who can thi merely send their own charts i Hope Technical Develo ments had on display the Hol Compensator. This device claimed to increase spring sti ness on a trailer as the out begins to turn a corner, till cutting down the roll.
It senses off the fifth wher where control valves then sign to the compensator ur mounted on the frame above ti springs. The compensator thr stiffens the suspension on tl appropriate side for the duratic of the turn. In essence the cor pensator uses a similar princip to the well-known Hope an jack-knife device.
