THE claim that a cab framework based on the use of both steel and light-alloy sections has the advantage over other methods of construction is " made by Dayson and Co. (Coachbuilders), Ltd., Watt Street, Birming
ham, 40. It is considered that if the cab is correctly designed, its weight is appreciably less than one with an all-alloy frame having a comparable strength.
The latest cab of composite steel and alloy, framing produced by the concern. is mounted on an Albion 6i-ton chassis with a Dayson light-alloy platform body. It has an unladen•weight of well under 3 tons, despite coachbuilt doors being fitted to the cab (at the operator's request) and the use of a heavy plank platform for carrying rolls of printing
paper each weighing 51 cwt. Tilt length of the body is 17 ft..
Molybdenum alloy -'steel squaresection tube is employed for the real framing and cant rails pf .the.cab, and the corner pillars are of special Metal Sections' half-round steel to accommodate a flat panel on one side apd curved panel on the adjaCent surface. The frame is braced by steel angle members, and all the joints are gusseted.
Light-alloy top-hat section is used for the cfoor-binge pillars and the wheelarch angle members. The side, door and roof panels are of 18-g, aluminium and the rear panels are of 20-g. alloy. The steel sections are anodized to obviate corrosion.
Small • fittings that reduce weight include interior door handles of plastic, and light-alloy steel-bushed hinges.
The body was built for Albion Motors, Ltd., and was supplied to Messrs. G. Ward and Son, Clifton Campville, near Tamworth.
