0N Tuesday of this week it was Taskers' turn to demonstrate the effectiveness of load-proportioning brake valves in making lightly laden or unladen artics safer.
Demonstrations by Taskers were staged at the FVRDE test ground at Chobbam, Surrey, and—as at Hendon—brake tests were made in various load conditions and unladen with and without the Clayton Dewandre load-proportioning valves in operation.
Taskers used a new AEC and an old ERF coupled to two of their semi-trailers and the demonstration confirmed that stability of the outfits was considerably improved on maximumpressure brake stops when unladen or part laden, with the device in operation.
The outfits were equipped with light-laden valves at their driving axles and semi-trailer axles and similar runs were made with the devices connected up and disconnected.
On tests in the latter condition—all were made from around 25 m.p.h.—the outfits folded or at least started to go into a jack-knife position when braked on a turn.
But on one pair of runs, although the outfit ended up in an almost complete jack-knife when the light-laden valves were not in use it appeared to have stopped in a shorter distance than when the use of the valves had made for complete stability.
