SOME 2,000-gallon articulated tankers with Eaton two-speed axles have recently been delivered to Trinidad Leaseholds, Ltd., for service in Jamaica. The vehicles comprise Austin Series II chort-wheelbase chassis with Taskers 9-ton semi-trailers.
The semi-trailer chassis have channel-steel frames "built down" at the rear to carry the semi-elliptic springs. Ventilated disc wheels carry twin 82520/35 by 71 12-ply tyres, a spare wheel and tyre being carried on the right-hand side of the trailer frame. The Girling two-leading-shoe brakes which are 16 ins, in diameter by 31 ins, wide, are operated by vacuum-servo equipment from the tractor. When the tractive unit is uncoupled, the semi-trailer is supported at the front by steerable screw-down jockey wheels to assist in man-handling.
The axle is of 31-in. square steel; the springs, which are of manganese steel, are 3 ft. 6 ins, long with 3-in.-wide leaves bushed at their ends and carried on 1-in.-diameter pins.

It is mounted on the semi-trailer on four pairs of fabricated bearer feet, the bearers being bolted to the semitrailer frame.
