FORMING the basis of a mobile show stand which will be used by Joseph Lucas, Ltd., Birmingham, the trailer chassis shown in the accompanying illustration was built by the Low Loading Trailer Co., Ltd., Bedford. The frame is built up of four light-section iongitudinal channels, braced by tubular cross-members. Maximum frame width is 6 ft. 8 ins., but is reduced behind the rear-spring hangers to accommodate the independently sprung wheel assemblies
The front wheels, which are 10 ins. less in track than those at the rear, are also independently sprung. By employing independent suspension all round, rolling tendencies have been eliminated. The wheels carry 27 by 6 high-pressure Lyres, and provision has been made for fitting twins should the outfit be required to traverse soft around.
When in use as a show stand, the trailer chassis will be supperted on four jacks, and provision for this has been made in the frame design. In connection with the braking system, the vacuum pipe line passes through a hollow turntable pin to a separate cylinder operating the rear-wheel brakes.
The turntable provides for a 90degree lock. The overall length of the chassis, is 19 ft. 6 ins.
Increasing use is being made of mobileshow stands, particularly in connection with agricultural shows. Users have fetund them to be practicable and economical.
