Haire Bag Suspension

	Using Haire Suspension, spring suspension can be changed over to air without fitting heavier, more expensive axles.  This is achieved by maintaining even pressure in all bags at all times.  No axle is expected to carry more weight than the other.
	Tipping on uneven terrain; not a problem with Haire Bags. With even pressure in all bags at all times the rear axle gains full travel. No axle is expected to carry more weight than the other. We can gain up to 12” of axle travel, this means that diff and cross locks are used less.
	Due to even air pressure in all air bags at all times the truck displays a greatly reduced tendency to roll over; both in off road and highway use. “I am very confident this design improvement will make a long term enhancement to road safety.” Dr Arnold McLean, PhD, BE Hons, FIEAust MASME
	With the tipper unladen and trailer laden the vehicle still has adequate traction to negotiate steep terrain without the use of differential or cross locks. "It is amazing where the truck will go while the trailer is being towed.” Trevor Koschel
	Traction is improved tremendously. This vehicle pulls 400t without diff locks!
	High centre of gravity loads; not a problem with Haire Suspension.
	This is the 2" id hose and fitting that allows for high controlled air flow.
	This system does not call on air from air systems to oscillate axles, it transfers air from bag to bag. This is due to the neutral positioning of the height control.
	With Haire Suspension, trailer sway can be greatly reduced. Reversing procedures are easier on the driver and vehicle.
