TWO interesting tandem-axle semi' trailers, both with integrally-constructed, light-alloy hopper bodies by Durarnin Engineering Co. Ltd., have recently been delivered by R. A. Dyson and Co. Ltd. One was supplied to Scottish and Newcastle Breweries Ltd_, the other to R. Silcock and Sons Ltd.
The Scottish and Newcastle Breweries unit is 26 ft. long by 8ft. wide by 10 ft. high with a capacity of 1,030 Cu. ft. Filling is through three roof apertures, each provided with a detachable canvas cover, whilst for discharge there are three centrally-positioned chutes under the body with rack-and-pinion-operated sliding doors.
On the semi-trailer for R. Silcock. which also has a capacity of more than 1,000 Cu. ft. there are also three discharge apertures, but one of these is at the extreme rear and loading is through a single roof aperture_ There is a compartment on this trailer between the hopper and the outer skin which can be used for storage of sheets and so on. This is lined with 0.5 in. plywood and provided with an access door on the nearside. Two quite different suspensions are employed on the two units: air suspension on the Silcock semi-trailer and a rubber-mounted, inverted-spring bogie on the other, but in both cases, braking equipment is 15.5 in.. by 6 in. with airpressure actuation through direct-acting cylinders, and 9,00-20 tyres are fitted.
