NEW wheel-load classifying and recording equipment -developed for the Road Research Laboratory operates so quickly that the individual wheel loads of a -tandemi bogie on a typical sixvdieelcr can easily be registered at speeds of up to 60' m.p.h. The minimum permissible separation between successive loads is only 25 milliseconds.
The equipment, 'developed by the M.E.L. Equipment Co. Ltd. principally for dealing with heavy commercial vehicles, has resistancestrain-gauge load cells in the weighbridge as -on previous R.R.L. recording devices but differs in having electronic registration and sorting of loads.
