THE STILLER GROUP has revamped its Hazchem tankers to boost their capacity by 5 %, cutting 7(X)journeys a year or 19,()00 miles from one of its contracts.
The Stockton-on-Tees firm made the changes to meet the deliveryneeds of Terra Nitrogen. The chemicals company has a minimum stock requirement but maximum storage level for nitric acid, which means that large quantities must be delivered to its customers on a regular basis
lo shave unladen weight. Stiller replaced the standard fittings on its triax le trailers with aluminium wheels and air tanks, and attached smaller spill boxes. The tractor units, which were up for renewal, were changed from Daf CF75s (with a 7.5-tonne unladen weight) toScania P420s (at 7.4 tonnes).The tanks were tipped to reposition the high-level cut-off point. Altogether. these changes increased the payload from 27.5 tonnes to 29 tonnes A Stiller spokesman explains: It was much more cost-effective to alter the kit than to buy new. Besides, it's something of a badge of honour to alter things to suit customer needs"
