This document has been prepared to assist operators and road asset managers in assessing the merits of utilising larger vehicle combinations in a transport task. The assessment process assumes that the vehicle is dedicated to a specific task, operating travel being 50% unladen and 50% laden. The task relativities are 1000 tonnes with a lead of 1000 kilometres. Equivalent Standard ESA’s are calculated by the average of the sum of ESA’s for zero load (empty) plus ESA’s Axles: for 100% load and multiplied by the number of trips as required for the transport task. Are predictions based on the averages for a range of equipment within each combination Vehicle tare weights: category. These estimates have been reviewed by a number of operators and confirmed as being representative of vehicles of the category. “real” Fuel consumption Are predictions based on accumulated averages where operation is nominally 50% estimates: unladen and 50% laden. Actual consumption will vary with operating conditions. Emissions: Reference is on total fuel consumption only. 20 metre 7 axle Truck & The maximum allowable mass limits for this combination at either CML or HML (for Dog: standard combination) is 55.5 tonnes. The maximum allowable mass limits for this combination at either CML or HML (for 19 metre 7 Axle standard combination) is 55.5 tonnes. Consists of a complying B-double with an additional complying leading trailer. B-triple: All combinations utilizing a converter dolly are configured with a tandem axle. The configured vertical imposed loading of a 6x4 prime mover is similar to the allowable Converter Dolly: imposed vertical loading of a tandem axle converter dolly. Consists of a complying B-double with an additional complying road train leading trailer AB-triple: and a complying converter dolly. Consists of a complying B-double with an additional complying converter dolly and BAB-Quad: additional complying set of B-double trailers.
