watch this, I hope this is the right one
Neat video. Lovin the starter....also the flywheel and clutch out there in the open.
Dad bought a quarry a mile from the sand pit in 1962. There was a D4 Cat(see video NCPOP posted above about the 60..the D4 is on the same trailer) with a D2 cable front 1/3 yard bucket on it for loading trucks. Smooth tracks, no grousers because of all the tight turns you make. There was also a TL20 Lorain shovel included with a 1/2 yard bucket. They were both purchased new by the previous owner in 1953. The Lorain was the same as the one parked in the trees in attached video.. The other video looks to be a little smaller machine. The shovel is the easiest of cable operated cranes to operate. I had already been operating clamshells(the hardest to operate) and draglines(easier to operate) so the shovel was a piece of cake. I was15 when I started operating the shovel. All these were mechanical, no air assist. I wonder why my back and shoulders hurt...........
Then in 1965 Dad bought a Hough, model HU rubber tired loader, no cab(see last video) with a 1 1/3 yard bucket. What a machine compared to loading trucks with the D4. When I sold out the biggest loaders I had were 8 yard machines.
