OWDER tankers designed to carry a maximum payload of 19 tons on an outfit of 32 tons g.t.w. are now in regular operation by Pickfords' tank haulage service, of Traffofd Park, Manchester. They can handle a whole range of products but have been allocated to the specific work of transporting powdered starch for Brown and Poison Ltd. from Trafford Park to Paisley and Banbury. Three vehicles of this type are in use, two of them on the Paisley route where they have given six months' highly satisfactory service.
Each outfit consists of an Atkinson T3266 tractive unit with Cummins engine and a Crane Fruehauf semi-trailer. The new tanks and ancillary equipment were designed by Knutsen and Co. Ltd., of Malvern Link, Worcestershire. Given the powerful tractive unit, the initial problem was to produce an outfit that would handle the maximum payload within the legal weight limit.
Considerable ingenuity was necessary to attain the required result and at the same time —tipping being necessary in order to shoot the load to the back—to achieve it within the limitations imposed by the length of the vehicle and the probable headroom at customers' establishments. In the outcome a stepped-frame trailer was used and satisfactory weight distribution achieved by having two aluminium tanks, of 680 cu.ft. capacity in front and 820 cu.ft. capacity at the rear. When tipping they are raised separately by Edbro tipping gears.
In order to obtain two tanks large enough within the maximum permissible length they had to be placed close together on the chassis, an interlocking device being intro
so that only one tank can be tipped at 3. Overall length of the outfit is 42 ft. Lnd normal height is 12 ft. 6 in., rising to at full tip.
-ious items of pipe gear are contained 'blister" at the back of the rear tank. tanks are pressure-discharged at the t pipeline running from the front tank Lozzle immediately below the rear tank
• The discharge gear has a working ire of 10 p.s.i., the necessary air being provided by a land-based compressor. There are two hatches in each tank and a walkway on top with ladder at the rear.
Work on the Brown and Poison runs is in the form of' continuous operation, based on a 24-hour day, five-day week. The two vehicles engaged on the Trafford Park to Paisley run are operated by a link of four drivers who are located at a changeover point in Carlisle. From there, two run south to make the collections and two drive north to Loading is by gravity at the Brown and Poison weighbridge, the starch being fed through the hatches on top of the tanks. The time occupied by this work is clearly dependent upon the type of equipment in use on the customers' premises and here it takes approximately _ one hour, the discharge requiring a similar period.
