Teaching old dogs

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
