[Class 108 (i)] An ambulance trailer having a substantially rectangular body 17 provided with superposed tiers of stretcher runners or supports 18 on each side of a central corridor is fitted at both ends with coupling devices 12, 13 whereby a number of trailers may be connected to form a road train. As shown, the coupling elements 12, 13 consist of horizontal swivel plates carried by brackets 15, 16 and connected by a vertical pivot pin 14. The trailer body is preferably suspended from a cranked axle 20 by means of longitudinal leaf springs 23. The wheel hubs have their axes upwardly and inwardly inclined so as to intersect at a point above the ground level approximately three-quarters of the diameter of the wheels.
