• Hoy Trailers and Robert B. Massey and Co Ltd, have extended their range of chassis-less refrigerated trailer vans with a single-axle drawbar trailer of 12 tons gtw.
The first two of these vehicles have been delivered to Eden Vale (North) Ltd, of Dewsbury, Yorkshire. They will be employed for the transport of dairy produce, including yoghurt.
Like the refrigerated semi-trailer vans recently introduced by Hoy and Massey, the drawbar vehicles combine maximum payload with minimum weight. The trailers were designed and constructed at the Dunstable premises of recently formed Hoy-Green Engineering, Ltd (CM March 3), and the refrigerated bodies are manufactured and fitted by Robert B. Massey at Market Weighton, Yorkshire.
The trailers are of all-welded construction, with the floor frame consisting of a lightweight rolled steel rave section, and pressed steel cross-members.
The front and rear axles are of the Rubery Owen TH. 1600 "S" series, with laminated slipper-ended road springs. The ball race turntable is bolted to the floor frame and fabricated under-frame.
The refrigerated bodies are designed to operate at medium temperatures, between 36deg F and 46deg F.
The trailers have an overall length of 22ft, and overall width is 8ft. Overall height is 1211 4in., and loading weight 4ft 4in.
The leading refrigerated vans of the Eden Vale units were also supplied by Robert B. Massey and are mounted on Ford D1314 134in. wheelbase chassis cabs, and powered
by Ford 360 Six turbo-charged dies engines.
The gross train weight is 22 tons, and ti overall train length 48ft.
