Why is it so??

big tyres!:o

As another person who has travels around qld a far bit. And you are right there is lots of road works at the moment. Last week went from Brisbane to Roma to longreach to Emerald to Rockhampton to Gladstone to Bunderburg and back to Brisbane. And on every road there was loads of road works.

But one question on road works

What do the big steam roller looking style trucks but with the spikes instead of flat actually do.

Over here we call them "sheeps' foot tampers." The spikes concentrates the weight of the roller, increasing the compression of the fill before the next layer of fill is put on top. Makes for a more stable build up of earth.

This kind of setup?

It seems Im qualified to answer both questions about roadworks as its what they chuck money at me to fill my day in.
Grader wheel lean,as somebody mentioned,it helps counter the force of the load the mulboard is mooving,we lean the wheels over opposite to the way they want to slip.Gary,leaning the wheels whilst turning only marginally helps the turning circle,on a "lever" operated machine you run out of hands;););););),can be used on a joystick operated machine like mine as its a thumb movement to do so.To reduce turning circle we articulale the machine.

Padfoot/Sheepfoot rollers.They are used when compacting materials with a high clay content.

Hope this helps.

Ah Andy the luxury of modern machines, the cat 12 Es I did my time on, no articulation, wrist breaking dog clutch levers, stinking hot smelly things, the good old days not...I used to be able to drive these things, but no way could I operate one, unless you wanted a bmx track " which of course weren't around then we had dragsters" I as a then mechanic I take my hat off to you operators, a real skill ...Gary
