a. Axles are "closely spaced" if:
i. In the case of two axles they are spaced at distances apart of 2.5m or less.
ii. In the case of three axles the outermost axles are spaced at distances apart of 2.75m or less and no plated axle weight is more than 7 tons.
b. i. No closely spaced axle shall exceed 10 tons in weight.
ii. Where two axles are spaced at distances apart of not less than the measurement shown in Column 1 of Table 2 below the sum of the plated weight of those axles may amount to but shall not exceed the weight shown in Column 2 of that table save as provided in paragraph iii below.
iii. Where two axles are spaced at distances apart of not less than the measurement shown in Column 1 of Table 2 below the sum of the plated weights of those axles may amount to but shall not exceed the weight shown in Column 3 of that table provided that no axle is plated at more than half the weight shown in Column 3.
week and in his opinion the 22-ton-gvw six-wheeler at 15ft tin axle spread will suit a 6 cu.yd cement mixer perfectly. The 24-ton-gvw design would take a Foden bogie rated at 18.5 tons and spaced at 4ft 6in. As to eight-wheelers, he did not see much future for the 26-tonner but thought that the 28-tonner with 18-ton bogie and 19ft Sin outer axle spread would give a significant increase in payload and yet still be manoeuvrable.
A Scammell spokesman said this week that operators could probably take advantage of some of the proposals with certain current models for instance there would be no problem in replating some Routeman III trucks at 28 tons. In addition to current 26-ton models, 28-ton-gvw types have already been designed and 30-ton-gvw vehicles are well advanced in their development. Other new models which Scammell is developing include maximumcapacity six-wheelers based on the Routeman III design, sharing major and minor components with the 8 x 4 models.
As for attics, it should be possible under the proposals to build a 32-ton-gcw four-axle artic having an outer axle spread of 2711 compared with the minimum of 38ft for this configuration at present. One effect of the proposals may be that the three-axle tractive unit will virtually disappear, at least while 32 tons remains the top limit, since the two-axle unit under the new plan. can be plated at 16 tons provided it has a wheelbase of at least 7.9ft.
