YORK'S most successfulrange is undoubtedly its Freightmaster integral van semi-trailers which are offered in capacities of from 8 to 25 tons and in lengths of from

22 to 40 ft. At last year's Commercial Motor Show, York introduced its Teamster range of platform semi-trailers which consists of single-axle units of 14-ton capacity and 17to 27-ton capacity tandem-axle models. For this range a rolled-steel frame is used, this being a parallel-flange labeam of a high yield point steel, castellated to obtain strength with low weight. The same type of 1-section beam but not castellated is used fora 12-ton single-axle and a 15-ton twin-oscillating-axle model also produced but platform models below these capacities have rolled-steel-joist frames. These lower capacities are 7and 11-tonners which arc offered with fifth-wheel or automatic coupling, the same choice applying to the 12tonners and Freightmasters up to 12-ton capacity. The Teamster range is offered with fifth-wheel coupling only.

All York semi-trailers have one of four slandard suspensions; single and tandem axle designs have slipper-mounted leaf springs with axle location by adjustable rubber-bushed radius rods and are built of interchangeable components. The rear ends of the springs on each side in the tandem-axle layout are joined by rocker beams to prevent "axle hop ". Air suspension is an alternative on the tandem axle models.

Other York "trailer products include steelcoil carriers, extendible semi-trailers--called Trombone—and models with bodies to meet

T.I.R. requirements are available. Two types of semi-trailer coupling are made; the Yorkmatie interchangeable coupler, which allows a tractive unit to be operated with both fifth-wheel and automatic-type semitrailers and the Big-D fifth-wheel coupling which has a capacity of 50 tons,
