THE accompanying illustrations show a trailer attachment which has recently been constructed by R. A. Dyson and Co., Ltd., 76-80 Grafton Street, Liverpool, for work in conjunction with a Scammell tractor, the outfit having been supplied to Mr. Isaac Barrie, 32, Midland Street, Glasgow. The vehicle is designed to carry a load of 50 tons.
There are four wheels in line at the rear, arranged in pairs, mounted on
oscillating axles. These are bolted by permanently fixed hinged bolts to the tapered rear end of the chassis. When it is required to remove the rear wheels, so as to assist in unloading, it is-simply necessary to place two small jacks under the platforms provided at the rear of the attachments, slacken off two bolts and run the wheels clear of the job. The end of the chassis is then lowered to ground level by means of the jacks, the whole operation occupying only a few minutes.
The wheels are equipped with 771 by 180 twin solid-rubber tyres, and a clear platform space of 18 ft. by 9 ft. is provided, whilst the upper platform at the front is approximately 7 ft. 6 ins. by 10 ft.
The chassis frame, which is of box section, is arranged to take cranes, locomotives and other steel-wheeled outfits of 5-ft. 6-in. gauge. An oak platform is provided for carrying general heavy pieces of machinery, boilers, etc., but this is readily removable when it is desired to carry loco
motives. Forecarriages are available for this model, so that it can be easily converted to a trailer.
