Dog domination

Before PBS: Same footprint, different mass • General access: – 19 m B-double 50. 5 t – 19 m truck and dog 50. 5 t (Less in some states) • B-double access: – 19 m B-double 57. 5 t – Dogs went hungry – Safety reasons

After PBS • General access 50. 5 tonnes • B-double access 57. 5 tonnes • As long as certain requirements met – e. g. Bin height limit • Can these weights be introduced generally, without PBS approval?

Typical template - dimensions These dimensions are not critical!

Typical template – bin height • Bin height limits necessary – Level 1 – High Speed Transient Offtracking – Level 2 – Rearward Amplification • Suspensions and tyres – Broader range works for lower bin height – Narrower range works for higher bin height – Up to 2. 85 m typical for quarry work with a good range of suspensions

Managing risk • Many non-PBS vehicles do not meet PBS standards • A prescriptive approach should not require 100% certainty of meeting standards • We should be satisfied with vehicles ‘probably’ meeting the standards

Proposal - dimensions • Key longitudinal dimensions to be within broad specified ranges • 2. 85 m height limit • Bridge formulae • No need for further constraint

Proposal – suspensions, tyres • Suspensions – Certified RFS all positions except steer • Tyres – No conditions

Proposal – truck specs • 6. 5 tonne steer axle requirements – Emissions ADR 80/01 (Euro IV) or later – FUPD UN ECE Reg 93 – Cab strength UN ECE Reg 29 • ABS or EBS • Minimum 410 HP

Proposal – trailer specs • EBS with roll stability

National policy development • Should commence ASAP • Should involve: – PBS Assessors – PBS Certifiers – Truck and trailer manufacturers – End users – Not road authorities
