Dog domination
Before PBS: Same footprint, different mass
• General access:– 19m B-double 50.5 t– 19m truck and dog 50.5 t
(Less in some states)• B-double access:
– 19m 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
