Yep, MANY a small vehicle has been 'ex-TERMINATED' by various types of earthmoving and construction equipment when the operator could not see it. I remember a (long) past employer of mine cleaning up a freshly-excavated farm dam with a D8H fitted with hinged rippers. He backed up the open mouth of the dam at the same time as the farmer's wife drove up and parked there with the family's brand spanking new Ford station wagon. The D8 topped the bank and the back end dropped down flat. Two ripper shanks through the passenger side doors later, - - - - - - - - - - - ?????????????????
I also saw a fitter try to park a 65-ton Haulpak in the back of a Chrysler pick-up one day. Surprisingly, they replaced the left rear wheel, brake backing plate and brake shoes and it was a goer again - ran around the mine for about four months before they sold it for $400.00 to an operator who was leaving the job . He promptly drove it around 1,000 miles down to Perth in Western Australia and sold it for $1,200.00.
D'yer think we ought to tell all the 'cowboys' that the flags are NOT for target practice as well as just putting them on the vehicles? I suspect that the Polaris and the Blaap-Blaaaaap could probably outrun most of the machines on a good day anyway. How does the Argo 8-wheeler on tracks go for pace? Maybe the electric golf cart might need to stay on the fringes of the work area?
There'll be things to sort out, maybe as we go, but I don't think there is a lot to worry about. Most of the guys have been there, done that B4.
