CHANCES AT LEEM
1VELY topics, 127 enthusiastic ( hibitors and several innovatic added up to an interesting two-d event, held at Leeds University a sponsored by the Institute of Re Transport Engineers' Yorkshire brand But despite the traditional northc holidays and ample publicity, ma IRTE members and transport people the area did riot take advantage of wl was on offer at the Forum and Displa According to the best estimate of t organiser — the university's conferem department — 450 people attended. I many were key industry people from far afield as Dorset and the North Ea and technical salesmen had plenty time to devote to their enquiries.
lE FIRST tri-axle tipping chassis m Neville Charrold built to the npany's new design (for Andrew ck of Drem, East Lothian), had a mm (15in) step and was istructed on three-piece fabricated s, see bottom left.
['he chassis weighs 3,900kg luding Edbro tipping gear, and is unted on RO-R Indair pension with front and rear axle . Both lift controls are mounted the outside of the chassis, along :h a park control and an chorlok device that allows Lilting without coupling up to the =dye unit.
weight sensing device is luded for an extra £100. This uses sors in each air bag to gauge the ight across the axles. Renault had its first production G260 twin-steer tractive unit on display at Leeds — a York-converted vehicle on its original 3.6m wheelbase, see top right. With sleeper cab, the G260 6 x 2 weighs 7,065 tonnes, allowing for a full tank and 75kg driver.
A 290hp version will be available later this year, in time for the Scottish Motor Show. This will have the GT cab which was seen at the Paris Show.
Engine abuse and over speeding can be eliminated, says Torque of Rochdale, by its latest speed discipline device for cars and commercial vehicles, see top left, this page. On the cv model (050 excluding vat) engine revs and road speed are controlled using sensors on the generator and tachograph head.
The microprocessor-controlled system uses a pneumatic cylinder attached to the accelerator linkage, fed by an armoured and tamperproof air supply. A traffic-light sequence on the dash-mounted warning indicator warns the driver visually and audibly when he is driving to excess.
Torque has secured a contract to supply 1,200 cv units to an overseas bus company.
Although best known for its electronic devices, Torque also exhibited its Tip-Tow tipping trailer and pick-up body conversion, see centre. The system uses a patented pvc air bag between the tipping body and chassis which is inflated from the exhaust tail pipe on tickover.
A valve in the inflator pipe nozzle controls the pressure up to around five psi to raise the body. When turned by hand the valve releases the pressure to lower it. Trailers on show included a one-tonne unit priced at £500 and a half-tonne box version at £450.
Torque is currently seeking a marketing company for the portable version for pick-ups which weighs around 75kg (1.5cwt).
