That must be the OH&S guy assessing the situation standing in the sun.Is skincancer worse than being squished under a backhoe? Neil

Yes, those Backhoes do have good Hydraulics , when the hoses are good , 

I was an B/H Operator many years ago, worked on the installation of the Coax Cable for the P.M.G. Dept in the N/W ,

I had a near new machine mounted on a Ford 5000 tractor, one day the Boom lifting hose blew with-out any warning, the whole arm assembly crashed to the ground, scared hell out of every-one near the workings, but luckily no-one was hit, just shows, ya never know when your time could be up,

This goes for those Idiot's  sitting under that Machine, one blown hose and they would all be history !!!
