Why so many suspensions

Chalmers???

....and KW's own 'Big Six' ' six rod suspension.....?

From the HCVC Facebook page 

I remember the wire rope suspensions one year at the truck show .........Id think they lasted about as long as fibreglass trailer springs ,that I also saw at the truck show one year.

I'm guessing a lot would depend on wereothe sales yards are located

With farm machinery the makes the dominate areas are generally those that are sold locally 

Thinking trucks are gunna be similar 

I gotta say thats a lite trailer compared to a McGrath

Norde Suspension from the UK. Hendrickson now owns them. I am sure that in the 80's 90's Kenworth offered that suspension as an option. I am sure Gordon Martin from Singleton had that type of suspension on one of his Kenworth semi tipper trucks. Roughly it looked like a Hendrickson walking beam with 2 rubber blocks (4 in total) set at 90 degrees above the centre of the walking beam. 

no x perience here
but
wot eye have heard
Boomerang  cable suspension tends to wear the cable where it touches the pulleys
and also cornering the cable lifts off the pulleys when hookin into it

Commonly called "Rubber Block Suspension" here, it was also popular on concrete agitators. 

Similar rubber springs used on the suburban electric trains here ......I think in UK,mainly Fodens had odd rubber suspensions ,and Fodens were owned by Paccar.
