Yep, if you were there,, post me a response.
There was an incident with an Aveling Barford Roller on the steep going back to Falevao when the operator lost his brakes. He was supposed to ditch the roller to stop it as soon as possible, a safety measure.This operator, being a distant relative of Michael Schumacher, decided to ride it down the mountain. His crew working down the road, hurriedly threw palm trunks across the road to try and slow down and stop this runaway roller. The roller's weight and increasing speed (mass X speed = momentum whereas mass X acceleration= force) just flattened these palm trunks like pancakes, but eventually at the flat down at Falevao, the operator having enjoyed the ride and very calm, got out with a big grin. I was sent down to retrieve the roller for a safety check and repairs, and overheard the crew getting a thorough safety and ditching lecture from their boss, for the umpteenth time.
I got to admire the technology used in these rollers considering their dates of manufacture, longetivity of service, and the hectic paces they are put through. They are still running around today, and a few with latter modifications like hydraulic power steering.
Aveling Barford Rollers have been if not still are manufactured in Great Britain by the:


hopefully the English.

My very first job was sorting out and repairing the power steering, on one of these Aveling Barford Rollers, which was mechanical and chain driven off the engine.
To drive straight, your steering hand had to constantly twitch right and left.
I also became a master at preloading the rear wheel bearings, with different shim plates and thicknesses before mounting the wheels on.
Brake system are by Girling, same as the Land Rover Cars.







Singhy(one of Ted's crew), operated a grader like this one, which I serviced a few times.

Singhy was an Indian gentleman on contract from Fiji.
This piece of machinery was very reliable and can do the same speeds forward as in reverse. Singhy used to be pulled out of the ditch more than a few times because he always would not pass up an opportunity to do 90 mph in reverse.
